I am using kendo-charts for the graphs in my project and, I understood it has default colors each streams .Issue is when i set a color to those streams still it shows the default color

html

<kendo-chart [categoryAxis]="{ categories: categories }" #primeChart [transitions]="transitions">

                    <kendo-chart-series>

                    </kendo-chart-series>
                </kendo-chart>

Answer 1

Found it my self add a view child to the chart element.( as already appears in html)

@ViewChild('primeChart') primeChart: any;

in the data setting method catch the primeChart element using this.primeChart

this.primeChart.theme.seriesColors=["green","red","green","red"]

this overrides the default series colors successfully
