Configuring Chart Axes
The vdl-chart-axis element has several possible attributes:
- axis: This string value can be set to x or y
- min: The minimum bound for the axis – it must be specified if you are using the max attribute
- max: The maximum bound for the axis – it must be specified if you are using the min attribute
- step: The step increment for the axis
- unit: The unit for the axis, e.g. cm
- type: A string that can be set to linear, log, date or category (default unless all series are of type scatter/line, when it defaults to linear)
- title: A string used as a title for an axis, which can be a dynamic expression
- show-grid: A boolean, defaulting to true, which controls whether or not a background grid is rendered – this can also be the result of a dynamic expression
The above attributes can give rise to VDL charts defined, for example, as:
<vdl-chart> <vdl-chart-axis axis=”x” min=”0” max=”100” step=”20” units=”cm” type=”category”/> <vdl-chart-axis axis=”y” min=”0” max=”100” step=”20” units=”cm” type=”category”/> </vdl-chart>
