a chart with a `size` sets it to its `ratio` | | `--tt-chart-max-height` | `480px`; not applied to a chart with a `size` | | `--tt-chart-width` | Set on a chart with a `size`: its share of the column, such as `50%` | | `--tt-chart-handle-color` | `#6a00f5`, the fill of a resize handle | | `--tt-chart-handle-border` | `#ffffff` | | `--tt-chart-handle-radius` | `4px` | | `--tt-chart-selected-outline` | `2px solid #6a00f5` | | `--tt-chart-loading-opacity` | `0.5` | | `--tt-chart-error-color` | `#e5484d` | | `--tt-chart-unavailable-color` | `#71717a` | | `--tt-chart-maximized-inset` | `0`: the distance of a maximized chart from the edges of the window, as for `inset` | | `--tt-chart-maximized-z-index` | `50` | | `--tt-chart-maximized-background` | `--tt-chart-background`, or `Canvas` when that is unset | - **A maximized chart** is `position: fixed`. - **If an ancestor of the editor sets `transform`, `filter` or `contain`**, a maximized chart is placed relative to that ancestor instead of the window. ### Drawing Read by every Renderer when a chart is drawn. | Property | Default | | --------------------------------------------- | -------------------------------------------------------------------------------------- | | `--tt-chart-series-1` … `--tt-chart-series-8` | `#6a00f5`, `#00a3a3`, `#f59e0b`, `#e5484d`, `#3b82f6`, `#16a34a`, `#d946ef`, `#64748b` | | `--tt-chart-axis-color` | `#9ca3af` | | `--tt-chart-grid-color` | `#e5e7eb` | | `--tt-chart-label-color` | `#4b5563` | | `--tt-chart-title-color` | `#111827` | | `--tt-chart-font-family` | `Arial, Helvetica, "Liberation Sans", sans-serif` | | `--tt-chart-font-size` | `12px` | | `--tt-chart-title-size` | `16px` | | `--tt-chart-title-weight` | `600` | | `--tt-chart-legend-gap` | `16px` | | `--tt-chart-legend-marker-size` | `10px` | - **Sizes** are pixels, written with or without `px`. Other units are not converted. - **A `palette` in the Chart Spec** overrides the series colors for that chart. #### Fonts in exports and Word - **An exported image** can only use fonts installed on the machine that exports it. - **A web font the page loaded** is not available to an exported image. - **A native Word chart** names a single typeface: the first family of `--tt-chart-font-family` that Word ships with (`WORD_FONTS`), a generic family as its Word counterpart, or `fallbackFont` (`'Arial'`). - **`wordFontFor(fontFamily)`** tells whether Word will draw a different face than the page. ### Quick Input | Property | Default | | -------------------------------------- | ------------------------------------------------------------- | | `--tt-diagram-input-radius` | `8px` | | `--tt-diagram-input-background` | `#f4f4f5` | | `--tt-diagram-input-color` | `inherit` | | `--tt-diagram-input-font-family` | `ui-monospace, monospace` | | `--tt-diagram-input-delimiter-color` | `#6a00f5` | | `--tt-diagram-input-placeholder-color` | `#a1a1aa` | | `--tt-diagram-input-placeholder-lines` | Set on an empty box to the number of lines of its placeholder | | `--tt-diagram-input-cell-background` | `#f4f4f5` | ### Highlighted source In the Quick Input, in a Mermaid diagram's code view, and in any element with the class `tiptap-diagram-source`, such as a source editor of your own.
