Hello,

The background color of the plot area can be configured as of the 2.30.0 release:

https://www.telerik.com/support/whats-new/blazor-ui/release-history/ui-for-blazor-2-30-0-blazor-2-30-0

The following code demonstrates the customization:

<TelerikChart>
    <ChartPlotArea Background="yellow" ></ChartPlotArea>
    ...
</TelerikChart>

As previously explained, configuring the color for other parts of the plot area will be handled in separate feature requests.

Hello Nikolas,

I think you are looking for a feature we call Plot Bands: https://feedback.telerik.com/blazor/1520686-is-it-possible-to-change-the-plot-area-background-color-in-an-alternating-way-plot-bands. If so, click the Vote and Follow buttons there. This is not something that can be achieved with a plain background color setting.

Hello,

As a workaround, you can use some CSS rules to target the plot area and change it's color. If there are multiple Charts on the same view their plot areas will all be colored the same way.

CSS:

<style>
    .k-chart svg > g > path:nth-child(2) { 
        fill: green !important;
        fill-opacity: 1 !important;
    }
</style>
