Template string used for rendering the information that appear on hover box. Note that this will override `hoverinfo`. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%_xother}, {%_xother_}, {%xother_}. When showing info for several points, *xother* will be added to those with different x positions from the first point. An underscore before or after *(x|y)other* will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available in `hovertemplate` are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available. variables `count`, `probability`, `category`, `categorycount`, `colorcount` and `bandcolorcount`. Anything contained in tag `<extra>` is displayed in the secondary box, for example "<extra>{fullData.name}</extra>". To hide the secondary box completely, use an empty tag `<extra></extra>`.

Sets the font for the `dimension` labels.

Determines whether the colorscale is a default palette (`autocolorscale: true`) or the palette determined by `line.colorscale`. Has an effect only if in `line.color`is set to a numerical array. In case `colorscale` is unspecified or `autocolorscale` is true, the default  palette will be chosen according to whether numbers in the `color` array are all positive, all negative or mixed.

Determines whether or not the color domain is computed with respect to the input data (here in `line.color`) or the bounds set in `line.cmin` and `line.cmax`  Has an effect only if in `line.color`is set to a numerical array. Defaults to `false` when `line.cmin` and `line.cmax` are set by the user.
