</script>Usage and data
#Compare market totals alongside product shares.
Both width and vertical proportions vary. Supplement precise values with tooltips or a table.
Data contract
| Property | Input format |
|---|---|
series | An array of { name, values }. Columns in values correspond to categories. |
categories | Names of the groups whose widths are compared. |
Updating data
Assign a new array or object to the property instead of mutating values inside an array. Chart events provide selection results through event.detail. When disposing of the view, clean up ResizeObserver and event listeners registered by your app.

Key properties
| Attribute / Property | Type / Default | Description |
|---|---|---|
ReadonlyArray<MarimekkoSeries>Default: [] | An array of { name, values }. Columns in values correspond to categories. | |
ReadonlyArray<string>Default: undefined | Names of the groups whose widths are compared. | |
numberDefault: 680 | Chart width in pixels. Update with ResizeObserver when the container changes. | |
numberDefault: 380 | Chart height in pixels. | |
| brandLogo | stringDefault: undefined | The default is the Syidax logo. With the Pro chart.branding entitlement, use none or a PNG, JPEG, or WebP data URL. |
| brandPosition | 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right'Default: 'bottom-right' | The corner where the logo is anchored. Applies equally to Community and Pro, on screen and in image exports. |
| columnGap | numberDefault: 0.01 | Horizontal gap between columns as a fraction of each slot (0..0.3). |
| showColumnShare | booleanDefault: true | Show the per-column total percentage above each column. |
| xLabelMode | 'auto' | 'all' | 'thin' | 'rotate' | 'none'Default: undefined | How crowded category-axis (column) labels are decluttered. Default 'auto' thins labels horizontally. |
| xLabelRotation | numberDefault: undefined | Explicit category-label rotation in degrees (respected as a floor). |
| valueAxisLabel | stringDefault: undefined | Set as an HTML attribute or JavaScript property. type: string. |
| gridLines | CartesianGridLinesInputDefault: undefined | Allowed values: auto, off. Default: undefined. |
CartesianCrosshairInputDefault: undefined | Crosshair that follows the cursor across the plot. `true`/`'auto'` enables a snapping line; pass an object to set mode/snap/color/dash. | |
| chartTitle | stringDefault: undefined | The title inside the chart. Explain the data's unit and meaning alongside it. |
| chartSubtitle | stringDefault: undefined | The subtitle inside the chart. |
booleanDefault: true | Whether to show a legend for series or items. | |
| legendPosition | MarimekkoChartLegendPositionDefault: 'top' | Where the legend is positioned. |
| tooltipEnabled | booleanDefault: true | Set as an HTML attribute or JavaScript property. type: boolean. |
CartesianTooltipInputDefault: undefined | Tooltip settings for pointer-driven values, position, and content. | |
| animated | booleanDefault: false | Whether to animate initial display and data changes. |
| animationDuration | numberDefault: 600 | Animation duration in milliseconds. |
| animationEasing | MarimekkoChartEasingDefault: 'ease-out' | Allowed values: linear, ease-out, ease-in, ease-in-out. Default: 'ease-out'. |
| animationType | MarimekkoChartAnimationTypeDefault: undefined | Allowed values: initial, update. Default: undefined. |
Other properties 10
| Attribute / Property | Type / Default | Description |
|---|---|---|
| xLabelMaxCount | numberDefault: undefined | Hard cap on the number of category labels shown. |
string | ReadonlyArray<string>Default: '#2563eb' | Segment colours. Overrides the built-in per-series palette: a single CSS colour, an array, or a comma-separated string. Colour `i` applies to segment `i`; where the list is shorter than the segment count the built-in palette fills the remaining indices. A segment's own `color` (in `series`) always wins over this attribute. | |
| tooltipFormat | (detail: MarimekkoChartPointerEventDetail) => stringDefault: undefined | Pass as a JavaScript property. type: (detail: MarimekkoChartPointerEventDetail) => string. |
| enableMouseTracking | booleanDefault: true | Set as an HTML attribute or JavaScript property. type: boolean. |
| streamSource | MarimekkoChartStreamSourceDefault: undefined | A stream source for live data. Check the contract for the specific type. |
| streamWindow | numberDefault: undefined | The streaming data range to keep visible. |
| streamMax | numberDefault: undefined | The maximum number of streaming data points to retain. |
MarimekkoChartEngineModeDefault: 'auto' | Renderer selection: auto, standard, or pro. Engine selection is separate from permission to use a Pro chart type. | |
| proThreshold | numberDefault: 50_000 | Set as an HTML attribute or JavaScript property. type: number. |
MarimekkoChartUnavailableBehaviourDefault: 'fallback' | Allowed values: fallback, error, throw. Default: 'fallback'. |
