MATLAB Figure Reference: indicator Traces

A indicator trace is a struct inside fig.data which has type equal to 'indicator'. This section lists all of the valid keys that a indicator struct can contain.

An indicator is used to visualize a single `value` along with some contextual information such as `steps` or a `threshold`, using a combination of three visual elements: a number, a delta, and/or a gauge. Deltas are taken with respect to a `reference`. Gauges can be either angular or bullet (aka linear) gauges.

  • type
    Parent: data[type=indicator]
    Type: 'indicator'
  • name
    Parent: data[type=indicator]
    Type: string

    Sets the trace name. The trace name appears as the legend item and on hover.

  • title
    Parent: data[type=indicator]
    Type: struct containing one or more of the keys listed below.
    • align
      Parent: data[type=indicator].title
      Type: enumerated , one of ( 'left' | 'center' | 'right' )

      Sets the horizontal alignment of the title. It defaults to `center` except for bullet charts for which it defaults to right.

    • font
      Parent: data[type=indicator].title
      Type: struct containing one or more of the keys listed below.

      Set the font used to display the title

        Type: string

        HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include 'Arial', 'Balto', 'Courier New', 'Droid Sans', 'Droid Serif', 'Droid Sans Mono', 'Gravitas One', 'Old Standard TT', 'Open Sans', 'Overpass', 'PT Sans Narrow', 'Raleway', 'Times New Roman'.

  • gauge
    Parent: data[type=indicator]
    Type: struct containing one or more of the keys listed below.

    The gauge of the Indicator plot.

    • axis
      Parent: data[type=indicator].gauge
      Type: struct containing one or more of the keys listed below.
      • dtick
        Parent: data[type=indicator].gauge.axis
        Type: number or categorical coordinate string

        Sets the step in-between ticks on this axis. Use with `tick0`. Must be a positive number, or special strings available to 'log' and 'date' axes. If the axis `type` is 'log', then ticks are set every 10^(n'dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. 'log' has several special values; 'L<f>', where `f` is a positive number, gives ticks linearly spaced in value (but not position). For example `tick0` = 0.1, `dtick` = 'L0.5' will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use 'D1' (all digits) or 'D2' (only 2 and 5). `tick0` is ignored for 'D1' and 'D2'. If the axis `type` is 'date', then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set `dtick` to 86400000.0. 'date' also has special values 'M<n>' gives ticks spaced by a number of months. `n` must be a positive integer. To set ticks on the 15th of every third month, set `tick0` to '2000-01-15' and `dtick` to 'M3'. To set ticks every 4 years, set `dtick` to 'M48'

      • exponentformat
        Parent: data[type=indicator].gauge.axis
        Type: enumerated , one of ( 'none' | 'e' | 'E' | 'power' | 'SI' | 'B' )
        Default: 'B'

        Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If 'none', it appears as 1,000,000,000. If 'e', 1e+9. If 'E', 1E+9. If 'power', 1x10^9 (with 9 in a super script). If 'SI', 1G. If 'B', 1B.

      • labelalias
        Parent: data[type=indicator].gauge.axis
        Type: number or categorical coordinate string

        Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

      • minexponent
        Parent: data[type=indicator].gauge.axis
        Type: number greater than or equal to 0
        Default: 3

If the axis `type` is 'date', it should be a date string, like date data. If the axis `type` is 'category', it should be a number, using the scale where each category is assigned a serial number from zero in the order it appears.

        Sets the tick label formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: '%h' for half of the year as a decimal number as well as '%{n}f' for fractional seconds with n digits. For example, '2016-10-13 09:15:23.456' with tickformat '%H~%M~%S.%2f' would display '09~15~23.46'

If 'array', the placement of the ticks is set via `tickvals` and the tick text is `ticktext`. ('array' is the default value if `tickvals` is provided).

  • uirevision
    Parent: data[type=indicator]
    Type: number or categorical coordinate string

    Controls persistence of some user-driven changes to the trace: `constraintrange` in `parcoords` traces, as well as some `editable: true` modifications such as `name` and `colorbar.title`. Defaults to `layout.uirevision`. Note that other user-driven trace attribute changes are controlled by `layout` attributes: `trace.visible` is controlled by `layout.legend.uirevision`, `selectedpoints` is controlled by `layout.selectionrevision`, and `colorbar.(x|y)` (accessible with `config: {editable: true}`) is controlled by `layout.editrevision`. Trace changes are tracked by `uid`, which only falls back on trace index if no `uid` is provided. So if your app can add/remove traces before the end of the `data` array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace a `uid` that stays with it as it moves.
