Multilevel Labels

Any number of levels of labels can be added to an axis using the multiLevelLabels property. This property can be configured using the following properties:

• Categories • Overflow • Alignment • Text style • Border

Note: To use multilevel label feature, we need to inject MultiLevelLabel into the @NgModule.providers.

Categories

Using the categories property, you can configure the start, end, text, and maximumTextWidth of multilevel labels.

Edge Label Placement

Labels with long text at the edges of an axis may appear partially in the chart. To avoid this, use edgeLabelPlacement property in axis, which moves the label inside the chart area for better appearance or hides it.

Line break support

Line break feature used to customize the long axis label text into multiple lines by using tag. Refer the below example in that dataSource x value contains long text, it breaks into two lines by using <br> tag.

Maximum Labels

MaximumLabels property is set, then the labels will be rendered based on the count in the property per 100 pixel. If you have set range (minimum, maximum, interval) and maximumLabels, then the priority goes to range only. If you haven’t set the range, then we have considered priority to maximumLabels property.
