But, if `none` is set, click and hover events are still fired. </li> <li> <a class="attribute-name" id="parcats-hovertemplate" href="#parcats-hovertemplate"> hovertemplate </a> Parent: <code>data[type=parcats]</code> Type: string Default: <code>""</code> 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. This value here applies when hovering over dimensions. Note that `"categorycount`, "colorcount" and "bandcolorcount" are only available when `hoveron` contains the "color" flagFinally, the template string has access to 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>`. </li> <li> <a class="attribute-name" id="parcats-meta" href="#parcats-meta"> meta </a> Parent: <code>data[type=parcats]</code> Type: number or categorical coordinate string Assigns extra meta information associated with this trace that can be used in various text attributes.

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. </li> <li> <a class="attribute-name" id="parcats-domain" href="#parcats-domain"> domain </a> Parent: <code>data[type=parcats]</code> Type: named list containing one or more of the keys listed below. <ul> <li> <a class="attribute-name" id="parcats-domain-column" href="#parcats-domain-column"> column </a> Parent: <code>data[type=parcats].domain</code> Type: integer greater than or equal to 0 Default: <code>0</code> If there is a layout grid, use the domain for this column in the grid for this parcats trace . </li> <li> <a class="attribute-name" id="parcats-domain-row" href="#parcats-domain-row"> row </a> Parent: <code>data[type=parcats].domain</code> Type: integer greater than or equal to 0 Default: <code>0</code> If there is a layout grid, use the domain for this row in the grid for this parcats trace . </li> <li> <a class="attribute-name" id="parcats-domain-x" href="#parcats-domain-x"> x </a> Parent: <code>data[type=parcats].domain</code> Type: list Default: <code>[0, 1]</code> Sets the horizontal domain of this parcats trace (in plot fraction). </li> <li> <a class="attribute-name" id="parcats-domain-y" href="#parcats-domain-y"> y </a> Parent: <code>data[type=parcats].domain</code> Type: list Default: <code>[0, 1]</code> Sets the vertical domain of this parcats trace (in plot fraction). </li> </ul> </li> <li> <a class="attribute-name" id="parcats-line" href="#parcats-line"> line </a> Parent: <code>data[type=parcats]</code> Type: named list containing one or more of the keys listed below. <ul> <li> <a class="attribute-name" id="parcats-line-autocolorscale" href="#parcats-line-autocolorscale"> autocolorscale </a> Parent: <code>data[type=parcats].line</code> Type: boolean Default: <code>TRUE</code> Determines whether the colorscale is a default palette (`autocolorscale: TRUE`) or the palette determined by `line.colorscale`.

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".

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.

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. </li> </ul> </div> </div>  </section> </div> </main> <footer class="--footer-main"> <section class="--footer-top"> <div class="--wrap"> <ul class="--footer-body"> <li class="--footer-column"> <h6 style="color:#119dff" class="--footer-heading">JOIN OUR MAILING LIST</h6>			 <ul> 				 <li> Sign up to stay in the loop with all things Plotly — from Dash Club to product updates, webinars, and more! <a href="https://go.plot.ly/subscription" class="subscribe-button" target="_blank"> Subscribe </a> </li> </ul> </li> 		 <li class="--footer-column"> <h6 style="color:#e763fa" class="--footer-heading">Products</h6>			 <ul> <li><a href="https://plotly.com/dash/" target="_self">Dash</a></li> 				 				 <li><a href="https://plotly.com/consulting-and-oem/" target="_self">Consulting and Training</a></li> </ul> </li> 		 <li class="--footer-column"> <h6 style="color:#636efa" class="--footer-heading">Pricing</h6>			 <ul> <li><a href="https://plotly.com/get-pricing/" target="_self">Enterprise Pricing</a></li> 				 </ul> </li> 		 <li class="--footer-column"> <h6 style="color:#00cc96" class="--footer-heading">About Us</h6>			 <ul> <li><a href="https://plotly.com/careers" target="_self">Careers</a></li> 				 <li><a href="https://plotly.com/resources/" target="_self">Resources</a></li> 				 <li><a href="https://medium.com/@plotlygraphs" target="_self">Blog</a></li> 				 </ul> </li> 		 <li class="--footer-column"> <h6 style="color:#EF553B" class="--footer-heading">Support</h6>			 <ul> <li><a href="https://community.plot.ly/" target="_self">Community Support</a></li> 				 <li><a href="https://plotly.com/graphing-libraries" target="_self">Documentation</a></li> 				 </ul> </li> </ul> </div> </section> <section class="--footer-meta"> <div class="--wrap"> <div class="left"> <article class="--copyright">Copyright © 2025 Plotly.
