JavaScript Figure Reference: ohlc Traces

A ohlc trace is an object with the key "type" equal to "ohlc" (i.e. {"type": "ohlc"}) and any of the keys listed below.

The ohlc (short for Open-High-Low-Close) is a style of financial chart describing open, high, low and close for a given `x` coordinate (most likely time). The tip of the lines represent the `low` and `high` values and the horizontal segments represent the `open` and `close` values. Sample points where the close value is higher (lower) then the open value are called increasing (decreasing). By default, increasing items are drawn in green whereas decreasing are drawn in red.

  • type
    Parent: data[type=ohlc]
    Type: "ohlc"
  • name
    Parent: data[type=ohlc]
    Type: string

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

  • visible
    Parent: data[type=ohlc]
    Type: enumerated , one of ( true | false | "legendonly" )
    Default: true

    Determines whether or not this trace is visible. If "legendonly", the trace is not drawn, but can appear as a legend item (provided that the legend itself is visible).

  • showlegend
    Parent: data[type=ohlc]
    Type: boolean
    Default: true

    Determines whether or not an item corresponding to this trace is shown in the legend.

  • legendgroup
    Parent: data[type=ohlc]
    Type: string
    Default: ""

    Sets the legend group for this trace. Traces part of the same legend group hide/show at the same time when toggling legend items.

  • opacity
    Parent: data[type=ohlc]
    Type: number between or equal to 0 and 1
    Default: 1

    Sets the opacity of the trace.

  • ids
    Parent: data[type=ohlc]
    Type: data array

    Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.

  • x
    Parent: data[type=ohlc]
    Type: data array

    Sets the x coordinates. If absent, linear coordinate will be generated.

  • close
    Parent: data[type=ohlc]
    Type: data array

    Sets the close values.

  • open
    Parent: data[type=ohlc]
    Type: data array

    Sets the open values.

  • high
    Parent: data[type=ohlc]
    Type: data array

    Sets the high values.

  • low
    Parent: data[type=ohlc]
    Type: data array

    Sets the low values.

  • text
    Parent: data[type=ohlc]
    Type: string or array of strings
    Default: ""

    Sets hover text elements associated with each sample point. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to this trace's sample points.

  • hovertext
    Parent: data[type=ohlc]
    Type: string or array of strings
    Default: ""

    Same as `text`.

  • hoverinfo
    Parent: data[type=ohlc]
    Type: flaglist string. Any combination of "x", "y", "z", "text", "name" joined with a "+" OR "all" or "none" or "skip".
    Examples: "x", "y", "x+y", "x+y+z", "all"
    Default: "all"

    Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

  • meta
    Parent: data[type=ohlc]
    Type: number or categorical coordinate string

    Assigns extra meta information associated with this trace that can be used in various text attributes. Attributes such as trace `name`, graph, axis and colorbar `title.text`, annotation `text` `rangeselector`, `updatemenues` and `sliders` `label` text all support `meta`. To access the trace `meta` values in an attribute in the same trace, simply use `%{meta[i]}` where `i` is the index or key of the `meta` item in question. To access trace `meta` in layout attributes, use `%{data[n[.meta[i]}` where `i` is the index or key of the `meta` and `n` is the trace index.

  • customdata
    Parent: data[type=ohlc]
    Type: data array

    Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, "scatter" traces also appends customdata items in the markers DOM elements

  • xaxis
    Parent: data[type=ohlc]
    Type: subplotid
    Default: x

    Sets a reference between this trace's x coordinates and a 2D cartesian x axis. If "x" (the default value), the x coordinates refer to `layout.xaxis`. If "x2", the x coordinates refer to `layout.xaxis2`, and so on.

  • yaxis
    Parent: data[type=ohlc]
    Type: subplotid
    Default: y

    Sets a reference between this trace's y coordinates and a 2D cartesian y axis. If "y" (the default value), the y coordinates refer to `layout.yaxis`. If "y2", the y coordinates refer to `layout.yaxis2`, and so on.

  • selectedpoints
    Parent: data[type=ohlc]
    Type: number or categorical coordinate string

    Array containing integer indices of selected points. Has an effect only for traces that support selections. Note that an empty array means an empty selection where the `unselected` are turned on for all points, whereas, any other non-array values means no selection all where the `selected` and `unselected` styles have no effect.

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".

    • namelength
      Parent: data[type=ohlc].hoverlabel
      Type: integer or array of integers greater than or equal to -1
      Default: 15

      Sets the default length (in number of characters) of the trace name in the hover labels for all traces. -1 shows the whole name regardless of length. 0-3 shows the first 0-3 characters, and an integer >3 will show the whole name if it is less than that many characters, but if it is longer, will truncate to `namelength - 3` characters and add an ellipsis.

    • split
      Parent: data[type=ohlc].hoverlabel
      Type: boolean

      Show hover information (open, close, high, low) in separate labels.

  • tickwidth

  • xcalendar
    Parent: data[type=ohlc]

    Default: "gregorian"

    Sets the calendar system to use with `x` date data.

  • uirevision
    Parent: data[type=ohlc]
    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.
