DISCLAIMER

This is an unofficial Plotly Perl module. Currently I'm not affiliated in any way with Plotly. But I think plotly.js is a great library and I want to use it with perl.

METHODS

TO_JSON

Serialize the trace to JSON. This method should be called only by JSON serializer.

ATTRIBUTES

• bgcolor

  Sets the color of padded area.

• bordercolor

  Sets the axis line color.

• borderwidth

  Sets the width (in px) or the border enclosing this color bar.

• dtick

  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; *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 *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

  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.

• len

  Sets the length of the color bar This measure excludes the padding of both ends. That is, the color bar length is this length minus the padding on both ends.

• lenmode

  Determines whether this color bar's length (i.e. the measure in the color variation direction) is set in units of plot *fraction* or in *pixels. Use `len` to set the value.

• minexponent

  Hide SI prefix for 10^n if |n| is below this number. This only has an effect when `tickformat` is *SI* or *B*.

• nticks

  Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to `nticks`. Has an effect only if `tickmode` is set to *auto*.

• orientation

  Sets the orientation of the colorbar.

• outlinecolor

  Sets the axis line color.

• outlinewidth

  Sets the width (in px) of the axis line.

• separatethousands

  If "true", even 4-digit integers are separated

• showexponent

  If *all*, all exponents are shown besides their significands. If *first*, only the exponent of the first tick is shown. If *last*, only the exponent of the last tick is shown. If *none*, no exponents appear.

• showticklabels

  Determines whether or not the tick labels are drawn.

• showtickprefix

  If *all*, all tick labels are displayed with a prefix. If *first*, only the first tick is displayed with a prefix. If *last*, only the last tick is displayed with a suffix. If *none*, tick prefixes are hidden.

• showticksuffix

  Same as `showtickprefix` but for tick suffixes.

• thickness

  Sets the thickness of the color bar This measure excludes the size of the padding, ticks and labels.

• thicknessmode

  Determines whether this color bar's thickness (i.e. the measure in the constant color direction) is set in units of plot *fraction* or in *pixels*. Use `thickness` to set the value.

• tick0

  Sets the placement of the first tick on this axis. Use with `dtick`. If the axis `type` is *log*, then you must take the log of your starting tick (e.g. to set the starting tick to 100, set the `tick0` to 2) except when `dtick`=*f* (see `dtick` for more info). 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.

• tickangle

  Sets the angle of the tick labels with respect to the horizontal. For example, a `tickangle` of -90 draws the tick labels vertically.

• tickcolor

  Sets the tick color.

• tickfont

• tickformat

  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*

• tickformatstops

• ticklabeloverflow

  Determines how we handle tick labels that would overflow either the graph div or the domain of the axis. The default value for inside tick labels is *hide past domain*. In other cases the default is *hide past div*.

• ticklabelposition

  Determines where tick labels are drawn relative to the ticks. Left and right options are used when `orientation` is *h*, top and bottom when `orientation` is *v*.

• ticklabelstep

  Sets the spacing between tick labels as compared to the spacing between ticks. A value of 1 (default) means each tick gets a label. A value of 2 means shows every 2nd label. A larger value n means only every nth tick is labeled. `tick0` determines which labels are shown. Not implemented for axes with `type` *log* or *multicategory*, or when `tickmode` is *array*.

• ticklen

  Sets the tick length (in px).

• tickmode

  Sets the tick mode for this axis. If *auto*, the number of ticks is set via `nticks`. If *linear*, the placement of the ticks is determined by a starting position `tick0` and a tick step `dtick` (*linear* is the default value if `tick0` and `dtick` are provided). 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).

• tickprefix

  Sets a tick label prefix.

• ticks

  Determines whether ticks are drawn or not. If **, this axis' ticks are not drawn. If *outside* (*inside*), this axis' are drawn outside (inside) the axis lines.

• ticksuffix

  Sets a tick label suffix.

• ticktext

  Sets the text displayed at the ticks position via `tickvals`. Only has an effect if `tickmode` is set to *array*. Used with `tickvals`.

• ticktextsrc

  Sets the source reference on Chart Studio Cloud for `ticktext`.

• tickvals

  Sets the values at which ticks on this axis appear. Only has an effect if `tickmode` is set to *array*. Used with `ticktext`.

• tickvalssrc

  Sets the source reference on Chart Studio Cloud for `tickvals`.

• tickwidth

  Sets the tick width (in px).

• title

• x

  Sets the x position of the color bar (in plot fraction). Defaults to 1.02 when `orientation` is *v* and 0.5 when `orientation` is *h*.

• xanchor

  Sets this color bar's horizontal position anchor. This anchor binds the `x` position to the *left*, *center* or *right* of the color bar. Defaults to *left* when `orientation` is *v* and *center* when `orientation` is *h*.

• xpad

  Sets the amount of padding (in px) along the x direction.

• y

  Sets the y position of the color bar (in plot fraction). Defaults to 0.5 when `orientation` is *v* and 1.02 when `orientation` is *h*.

• yanchor

  Sets this color bar's vertical position anchor This anchor binds the `y` position to the *top*, *middle* or *bottom* of the color bar. Defaults to *middle* when `orientation` is *v* and *bottom* when `orientation` is *h*.

• ypad

  Sets the amount of padding (in px) along the y direction.
