plotly.express package

plotly.express is a terse, consistent, high-level wrapper around plotly.graph_objects for rapid data exploration and figure generation. Learn more at https://plotly.com/python/plotly-express/

class plotly.express.Constant(value, label=None)

Bases: object

Objects of this class can be passed to Plotly Express functions that expect column identifiers or list-like objects to indicate that this attribute should take on a constant value. An optional label can be provided.

class plotly.express.IdentityMap

Bases: object

dict-like object which acts as if the value for any key is the key itself. Objects of this class can be passed in to arguments like color_discrete_map to use the provided data values as colors, rather than mapping them to colors cycled from color_discrete_sequence. This works for any _map argument to Plotly Express functions, such as line_dash_map and symbol_map.

class plotly.express.Range(label=None)

Bases: object

Objects of this class can be passed to Plotly Express functions that expect column identifiers or list-like objects to indicate that this attribute should be mapped onto integers starting at 0. An optional label can be provided.

In a stacked area plot, each row of data_frame is represented as vertex of a polyline mark in 2D space. The area between successive polylines is filled.

Parameters
  • data_frame (DataFrame or array-like or dict) – This argument needs to be passed for column names (and not keyword names) to be used. Array-like and dict are transformed internally to a pandas DataFrame. Optional: if missing, a DataFrame gets constructed under the hood using the other arguments.

  • x (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to position marks along the x axis in cartesian coordinates.

  • y (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to position marks along the y axis in cartesian coordinates.

  • hover_name (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like appear in bold in the hover tooltip.

  • hover_data (str, or list of str or int, or Series or array-like, or dict) – Either a name or list of names of columns in data_frame, or pandas Series, or array_like objects or a dict with column names as keys, with values True (for default formatting) False (in order to remove this column from hover information), or a formatting string, for example ‘:.3f’ or ‘|%a’ or list-like data to appear in the hover tooltip or tuples with a bool or formatting string as first element, and list-like data to appear in hover as second element Values from these columns appear as extra data in the hover tooltip.

  • custom_data (str, or list of str or int, or Series or array-like) – Either name or list of names of columns in data_frame, or pandas Series, or array_like objects Values from these columns are extra data, to be used in widgets or Dash callbacks for example. This data is not user-visible but is included in events emitted by the figure (lasso selection etc.)

When color is set and the values in the corresponding column are not numeric, values in that column are assigned colors by cycling through color_discrete_sequence in the order described in category_orders, unless the value of color is a key in color_discrete_map. Various useful color sequences are available in the plotly.express.colors submodules, specifically plotly.express.colors.qualitative.

  • color_discrete_map (dict with str keys and str values (default {})) – String values should define valid CSS-colors Used to override color_discrete_sequence to assign a specific colors to marks corresponding with specific values.

Alternatively, if the values of pattern_shape are valid patterns-shapes names, the string 'identity' may be passed to cause them to be used directly.

  • symbol_sequence (list of str) – Strings should define valid plotly.js symbols. When symbol is set, values in that column are assigned symbols by cycling through symbol_sequence in the order described in category_orders, unless the value of symbol is a key in symbol_map.

  • markers (boolean (default False)) – If True, markers are shown on lines.

  • orientation (str, one of 'h' for horizontal or 'v' for vertical.) – (default 'v' if x and y are provided and both continous or both categorical, otherwise 'v'`(‘h’) if `x`(`y) is categorical and y`(`x) is continuous, otherwise 'v'`(‘h’) if only `x`(`y) is provided)

  • groupnorm (str (default None)) – One of 'fraction' or 'percent'. If 'fraction', the value of each point is divided by the sum of all values at that location coordinate. 'percent' is the same but multiplied by 100 to show percentages. None will stack up all values at each location coordinate.

  • log_x (boolean (default False)) – If True, the x-axis is log-scaled in cartesian coordinates.

  • log_y (boolean (default False)) – If True, the y-axis is log-scaled in cartesian coordinates.

In a box plot, rows of data_frame are grouped together into a box-and-whisker mark to visualize their distribution.

Each box spans from quartile 1 (Q1) to quartile 3 (Q3). The second quartile (Q2) is marked by a line inside the box. By default, the whiskers correspond to the box’ edges +/- 1.5 times the interquartile range (IQR: Q3-Q1), see “points” for other options.

Parameters
  • data_frame (DataFrame or array-like or dict) – This argument needs to be passed for column names (and not keyword names) to be used.

  • y (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to position marks along the y axis in cartesian coordinates.

  • color (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to assign color to marks.

  • facet_row (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to assign marks to facetted subplots in the vertical direction.

  • facet_col (str or int or Series or array-like) – Either a name of a column in data_frame, or a pandas Series or array_like object. Values from this column or array_like are used to assign marks to facetted subplots in the horizontal direction.

Parameters
  • img (array-like image, or xarray) –

    The image data. Supported array shapes are

    • (M, N): an image with scalar data. The data is visualized using a colormap.

    • (M, N, 4): an image with RGBA values, i.e. including transparency.

  • zmin (scalar or iterable, optional) – zmin and zmax define the scalar range that the colormap covers. By default, zmin and zmax correspond to the min and max values of the datatype for integer datatypes (ie [0-255] for uint8 images, [0, 65535] for uint16 images, etc.). For a multichannel image of floats, the max of the image is computed and zmax is the smallest power of 256 (1, 255, 65535) greater than this max value, with a 5% tolerance. For a single-channel image, the max of the image is used. Overridden by range_color.

  • zmax (scalar or iterable, optional) – zmin and zmax define the scalar range that the colormap covers. By default, zmin and zmax correspond to the min and max values of the datatype for integer datatypes (ie [0-255] for uint8 images, [0, 65535] for uint16 images, etc.). For a multichannel image of floats, the max of the image is computed and zmax is the smallest power of 256 (1, 255, 65535) greater than this max value, with a 5% tolerance. For a single-channel image, the max of the image is used. Overridden by range_color.

  • origin (str, 'upper' or 'lower' (default 'upper')) – position of the [0, 0] pixel of the image array, in the upper left or lower left corner. The convention ‘upper’ is typically used for matrices and images.

  • labels (dict with str keys and str values (default {})) – Sets names used in the figure for axis titles (keys x and y), colorbar title and hoverlabel (key color). The values should correspond to the desired label to be displayed. If img is an xarray, dimension names are used for axis titles, and long name for the colorbar title (unless overridden in labels). Possible keys are: x, y, and color.

  • x (list-like, optional) – x and y are used to label the axes of single-channel heatmap visualizations and their lengths must match the lengths of the second and first dimensions of the img argument. They are auto-populated if the input is an xarray.

  • y (list-like, optional) – x and y are used to label the axes of single-channel heatmap visualizations and their lengths must match the lengths of the second and first dimensions of the img argument. They are auto-populated if the input is an xarray.

  • animation_frame (int or str, optional (default None)) – axis number along which the image array is sliced to create an animation plot. If img is an xarray, animation_frame can be the name of one the dimensions.

  • facet_col (int or str, optional (default None)) – axis number along which the image array is sliced to create a facetted plot. If img is an xarray, facet_col can be the name of one the dimensions.

  • facet_col_wrap (int) – Maximum number of facet columns. Wraps the column variable at this width, so that the column facets span multiple rows. Ignored if facet_col is None.

  • facet_col_spacing (float between 0 and 1) – Spacing between facet columns, in paper units. Default is 0.02.

  • facet_row_spacing (float between 0 and 1) – Spacing between facet rows created when facet_col_wrap is used, in paper units. Default is 0.0.7.

  • color_continuous_scale (str or list of str) – colormap used to map scalar data to colors (for a 2D image). This parameter is not used for RGB or RGBA images. If a string is provided, it should be the name of a known color scale, and if a list is provided, it should be a list of CSS- compatible colors.

  • color_continuous_midpoint (number) – If set, computes the bounds of the continuous color scale to have the desired midpoint. Overridden by range_color or zmin and zmax.

  • range_color (list of two numbers) – If provided, overrides auto-scaling on the continuous color scale, including overriding color_continuous_midpoint. Also overrides zmin and zmax. Used only for single-channel images.

  • title (str) – The figure title.

  • template (str or dict or plotly.graph_objects.layout.Template instance) – The figure template name or definition.

  • width (number) – The figure width in pixels.

  • height (number) – The figure height in pixels.

  • aspect ('equal', 'auto', or None) –

    • ‘equal’: Ensures an aspect ratio of 1 or pixels (square pixels)

    • ’auto’: The axes is kept fixed and the aspect ratio of pixels is adjusted so that the data fit in the axes. In general, this will result in non-square pixels.

    • if None, ‘equal’ is used for numpy arrays and ‘auto’ for xarrays (which have typically heterogeneous coordinates)

  • contrast_rescaling ('minmax', 'infer', or None) – how to determine data values corresponding to the bounds of the color range, when zmin or zmax are not passed. If minmax, the min and max values of the image are used. If infer, a heuristic based on the image data type is used.

  • binary_string (bool, default None) – if True, the image data are first rescaled and encoded as uint8 and then passed to plotly.js as a b64 PNG string. If False, data are passed unchanged as a numerical array. Setting to True may lead to performance gains, at the cost of a loss of precision depending on the original data type. If None, use_binary_string is set to True for multichannel (eg) RGB arrays, and to False for single-channel (2D) arrays. 2D arrays are represented as grayscale and with no colorbar if use_binary_string is True.

  • binary_backend (str, 'auto' (default), 'pil' or 'pypng') – Third-party package for the transformation of numpy arrays to png b64 strings. If ‘auto’, Pillow is used if installed, otherwise pypng.

  • binary_compression_level (int, between 0 and 9 (default 4)) – png compression level to be passed to the backend when transforming an array to a png b64 string. Increasing binary_compression decreases the size of the png string, but the compression step takes more time. For most images it is not worth using levels greater than 5, but it’s possible to test len(fig.data[0].source) and to time the execution of imshow to tune the level of compression. 0 means no compression (not recommended).

  • binary_format (str, 'png' (default) or 'jpg') – compression format used to generate b64 string. ‘png’ is recommended since it uses lossless compression, but ‘jpg’ (lossy) compression can result if smaller binary strings for natural images.

  • text_auto (bool or str (default False)) – If True or a string, single-channel img values will be displayed as text. A string like '.2f' will be interpreted as a texttemplate numeric formatting directive.

This parameter is used to force a specific ordering of values per column. The keys of this dict should correspond to column names, and the values should be lists of strings corresponding to the specific display order desired.

  • labels (dict with str keys and str values (default {})) – By default, column names are used in the figure for axis titles, legend entries and hovers. This parameter allows this to be overridden.

  • line_shape (str (default 'linear')) – One of 'linear' or 'spline'.

  • render_mode (str) – One of 'auto', 'svg' or 'webgl', default 'auto' Controls the browser API used to draw marks. 'svg’ is appropriate for figures of less than 1000 data points, and will allow for fully-vectorized output. 'webgl' is likely necessary for acceptable performance above 1000 points but rasterizes part of the output. 'auto' uses heuristics to choose the mode.

  • title (str) – The figure title.

  • template (str or dict or plotly.graph_objects.layout.Template instance) – The figure template name (must be a key in plotly.io.templates) or definition.

  • labels (dict with str keys and str values (default {})) – By default, column names are used in the figure for axis titles, legend entries and hovers. This parameter allows this to be overridden. The keys of this dict should correspond to column names, and the values should correspond to the desired label to be displayed.

  • color_discrete_sequence (list of str) – Strings should define valid CSS-colors. When color is set and the values in the corresponding column are not numeric, values in that column are assigned colors by cycling through color_discrete_sequence in the order described in category_orders, unless the value of color is a key in color_discrete_map. Various useful color sequences are available in the plotly.express.colors submodules, specifically plotly.express.colors.qualitative.

  • color_discrete_map (dict with str keys and str values (default {})) – String values should define valid CSS-colors Used to override color_discrete_sequence to assign a specific colors to marks corresponding with specific values. Keys in color_discrete_map should be values in the column denoted by color. Alternatively, if the values of color are valid colors, the string 'identity' may be passed to cause them to be used directly.

  • color_continuous_scale (list of str) – Strings should define valid CSS-colors This list is used to build a continuous color scale when the column denoted by color contains numeric data. Various useful color scales are available in the plotly.express.colors submodules, specifically plotly.express.colors.sequential, plotly.express.colors.diverging and plotly.express.colors.cyclical.

  • range_color (list of two numbers) – If provided, overrides auto-scaling on the continuous color scale.

  • render_mode (str) – One of 'auto', 'svg' or 'webgl', default 'auto' Controls the browser API used to draw marks. 'svg’ is appropriate for figures of less than 1000 data points, and will allow for fully-vectorized output. 'webgl' is likely necessary for acceptable performance above 1000 points but rasterizes part of the output. 'auto' uses heuristics to choose the mode.

  • title (str) – The figure title.

  • template (str or dict or plotly.graph_objects.layout.Template instance) – The figure template name (must be a key in plotly.io.templates) or definition.

Alternatively, if the values of pattern_shape are valid patterns-shapes names, the string 'identity' may be passed to cause them to be used directly.

  • color_continuous_scale (list of str) – Strings should define valid CSS-colors This list is used to build a continuous color scale when the column denoted by color contains numeric data.

plotly.express.imshow_utils module

Vendored code from scikit-image in order to limit the number of dependencies Extracted from scikit-image/skimage/exposure/exposure.py

plotly.express.imshow_utils.intensity_range(image, range_values='image', clip_negative=False)

Return image intensity range (min, max) based on desired value type.

Parameters
  • image (array) – Input image.

  • range_values (str or 2-tuple, optional) –

    The image intensity range is configured by this parameter. The possible values for this parameter are enumerated below.

    ’image’

    Return image min/max as the range.

    ’dtype’

    Return min/max of the image’s dtype as the range.

    dtype-name

    Return intensity range based on desired dtype. Must be valid key in DTYPE_RANGE. Note: image is ignored for this range type.

    2-tuple

    Return range_values as min/max intensities. Note that there’s no reason to use this function if you just want to specify the intensity range explicitly. This option is included for functions that use intensity_range to support all desired range types.

  • clip_negative (bool, optional) – If True, clip the negative range (i.e. return 0 for min intensity) even if the image dtype allows negative values.

plotly.express.imshow_utils.rescale_intensity(image, in_range='image', out_range='dtype')

Return image after stretching or shrinking its intensity levels.

The desired intensity range of the input and output, in_range and out_range respectively, are used to stretch or shrink the intensity range of the input image. See examples below.

Parameters
  • image (array) – Image array.

  • in_range (str or 2-tuple, optional) –

    Min and max intensity values of input and output image. The possible values for this parameter are enumerated below.

    ’image’

    Use image min/max as the intensity range.

    ’dtype’

    Use min/max of the image’s dtype as the intensity range.

    dtype-name

    Use intensity range based on desired dtype. Must be valid key in DTYPE_RANGE.

    2-tuple

    Use range_values as explicit min/max intensities.

  • out_range (str or 2-tuple, optional) –

    Min and max intensity values of input and output image. The possible values for this parameter are enumerated below.

    ’image’

    Use image min/max as the intensity range.

    ’dtype’

    Use min/max of the image’s dtype as the intensity range.

    dtype-name

    Use intensity range based on desired dtype. Must be valid key in DTYPE_RANGE.

    2-tuple

    Use range_values as explicit min/max intensities.

Returns

out – Image array after rescaling its intensity. This image is the same dtype as the input image.

Return type

array

Notes

Changed in version 0.17: The dtype of the output array has changed to match the output dtype, or float if the output range is specified by a pair of floats.

equalize_hist

Examples

By default, the min/max intensities of the input image are stretched to the limits allowed by the image’s dtype, since in_range defaults to ‘image’ and out_range defaults to ‘dtype’:

>>> image = np.array([51, 102, 153], dtype=np.uint8)
>>> rescale_intensity(image)
array([  0, 127, 255], dtype=uint8)

It’s easy to accidentally convert an image dtype from uint8 to float:

>>> 1.0 * image
array([ 51., 102., 153.])

Use rescale_intensity to rescale to the proper range for float dtypes:

>>> image_float = 1.0 * image
>>> rescale_intensity(image_float)
array([0. , 0.5, 1. ])

To maintain the low contrast of the original, use the in_range parameter:

>>> rescale_intensity(image_float, in_range=(0, 255))
array([0.2, 0.4, 0.6])

If the min/max value of in_range is more/less than the min/max image intensity, then the intensity levels are clipped:

>>> rescale_intensity(image_float, in_range=(0, 102))
array([0.5, 1. , 1. ])

If you have an image with signed integers but want to rescale the image to just the positive range, use the out_range parameter. In that case, the output dtype will be float:

>>> image = np.array([-10, 0, 10], dtype=np.int8)
>>> rescale_intensity(image, out_range=(0, 127))
array([  0. ,  63.5, 127. ])

To get the desired range with a specific dtype, use .astype():

>>> rescale_intensity(image, out_range=(0, 127)).astype(np.int8)
array([  0,  63, 127], dtype=int8)

If the input image is constant, the output will be clipped directly to the output range: >>> image = np.array([130, 130, 130], dtype=np.int32) >>> rescale_intensity(image, out_range=(0, 127)).astype(np.int32) array([127, 127, 127], dtype=int32)
