## Multiline data labels

Some components will display labels on mutliple lines when the provided text contains a line break. (example: "I contain\na line break").
Below is a table of the places where such line breaks can be used:

| Component | Label displayed | Where to use line breaks |
| --------------------------- | -------------------- | ------------------------------------------------------ |
| VueUiXy | Time labels (x axis) | config.chart.grid.labels.xAxisLabels.values |
| VueUiDonutEvolution | Time labels (x axis) | config.style.chart.layout.grid.xAxis.dataLabels.values |
| VueUiHistoryPlot | Plot labels | dataset names |
| VueUiParallelCoordinatePlot | Axis labels | config.style.chart.yAxis.labels.axisNames |
| VueUiQuadrant | Plot labels | dataset names |
| VueUiQuickChart | Time labels (x axis) | config.xyPeriods |
| VueUiRidgeline | Time labels (x axis) | config.style.chart.xAxis.labels.values |
| VueUiStackbar | Time labels (x axis) | config.style.chart.grid.x.timeLabels.values |
| VueUiStripPlot | x axis labels | dataset names |
