Waterfall
Waterfall charts are categorical charts which display the cumulative effect of sequentially introduced positive or negative values.
Basic Usage
The following example demonstrates the Waterfall chart in action.
@Component({

<kendo-chart-series-item type="waterfall"
[data]="cashFlowData" [color]="pointColor"

</kendo-chart-series-item-labels>
</kendo-chart-series-item>
</kendo-chart-series>
<kendo-chart-value-axis>
<kendo-chart-value-axis-item [labels]="{ format: 'C0' }">

export class AppComponent {
