Polar
Polar charts are scatter charts, which display two-dimensional data series in polar coordinates.
Basic Usage
The following example demonstrates the Polar chart in action.
@Component({
selector: 'my-app',
template: `
<kendo-chart [title]="{ text: 'Sun position at equinox' }">
<kendo-chart-series>
<kendo-chart-series-item type="polarLine" style="smooth"
[data]="sunPosData"
xField="azimuth" yField="altitude">
<kendo-chart-series-item-labels position="below"
[content]="labelContent">
</kendo-chart-series-item-labels>
</kendo-chart-series-item>
</kendo-chart-series>
<kendo-chart-x-axis>
<kendo-chart-x-axis-item [startAngle]="-90" [majorUnit]="30">
</kendo-chart-x-axis-item>
</kendo-chart-x-axis>
<kendo-chart-y-axis>
<kendo-chart-y-axis-item [labels]="{ visible: false }">
</kendo-chart-y-axis-item>
</kendo-chart-y-axis>
</kendo-chart>
`
})
