YAxis

Unique identifier of the axis.

A single toggle to hide the axis while preserving interaction like dragging.

Default is true when a cheater plot is present on the axis, otherwise false

Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors.

Grid color is lightened by blending this with the plot background Individual pieces can override this.

Sets the axis type.

By default, plotly attempts to determined the axis type by looking into the data of the traces that referenced the axis in question.

Sets the axis type.

By default, plotly attempts to determined the axis type by looking into the data of the traces that referenced the axis in question.

Using strict a numeric string in trace data is not converted to a number.

Using convert types a numeric string in trace data may be treated as a number during automatic axis type detection. Defaults to layout.autotypenumbers.

Determines whether or not the range of this axis is computed in relation to the input data.

See rangemode for more info. If range is provided, then autorange is set to false.

If normal, the range is computed in relation to the extrema of the input data.

If tozero`, the range extends to 0, regardless of the input data If nonnegative, the range is non-negative, regardless of the input data. Applies only to linear axes.

Sets the range of this axis.

If the axis type is log, then you must take the log of your desired range (e.g. to set the range from 1 to 100, set the range from 0 to 2). If the axis type is date, it should be date strings, like date data, though Date objects and unix milliseconds will be accepted and converted to strings. If the axis type is category, it should be numbers, using the scale where each category is assigned a serial number from zero in the order it appears.

Determines whether or not this axis is zoom-able.

If true, then zoom is disabled.

If set to another axis id (e.g.

x2, y), the range of this axis changes together with the range of the corresponding axis such that the scale of pixels per unit is in a constant ratio. Both axes are still zoomable, but when you zoom one, the other will zoom the same amount, keeping a fixed midpoint. constrain and constraintoward determine how we enforce the constraint. You can chain these, ie yaxis: {scaleanchor: *x*}, xaxis2: {scaleanchor: *y*} but you can only link axes of the same type. The linked axis can have the opposite letter (to constrain the aspect ratio) or the same letter (to match scales across subplots). Loops (yaxis: {scaleanchor: *x*}, xaxis: {scaleanchor: *y*} or longer) are redundant and the last constraint encountered will be ignored to avoid possible inconsistent constraints via scaleratio. Note that setting axes simultaneously in both a scaleanchor and a matches constraint is currently forbidden.

If this axis is linked to another by scaleanchor, this determines the pixel to unit scale ratio.

For example, if this value is 10, then every unit on this axis spans 10 times the number of pixels as a unit on the linked axis. Use this for example to create an elevation profile where the vertical scale is exaggerated a fixed amount with respect to the horizontal.

If this axis needs to be compressed (either due to its own scaleanchor and scaleratio or those of the other axis), determines how that happens: by increasing the range, or by decreasing the domain.

Default is domain for axes containing image traces, range otherwise.

If this axis needs to be compressed (either due to its own scaleanchor and scaleratio or those of the other axis), determines which direction we push the originally specified plot area.

Options are left, center (default), and right for x axes, and top, middle (default), and bottom for y axes.

If set to another axis id (e.g.

x2, y), the range of this axis will match the range of the corresponding axis in data-coordinates space. Moreover, matching axes share auto-range values, category lists and histogram auto-bins. Note that setting axes simultaneously in both a scaleanchor and a matches constraint is currently forbidden. Moreover, note that matching axes must have the same type.

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).

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.

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=L (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.

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, 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 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

Sets the position of this axis in the plotting space (in normalized coordinates).

Specifies the ordering logic for the case of categorical variables.

By default, plotly uses trace, which specifies the order that is present in the data supplied. Set categoryorder to category ascending or category descending if order should be determined by the alphanumerical order of the category names. Set categoryorder to array to derive the ordering from the attribute categoryarray. If a category is not found in the categoryarray array, the sorting behavior for that attribute will be identical to the trace mode. The unspecified categories will follow the categories in categoryarray. Set categoryorder to total ascending or total descending if order should be determined by the numerical order of the values. Similarly, the order can be determined by the min, max, sum, mean or median of all the values.

Sets the order in which categories on this axis appear.

Only has an effect if categoryorder is set to array. Used with categoryorder.
