Hi @Preeti Mahajan ,

Here's a forum thread that might help you https://www.outsystems.com/forums/discussion/74096/tooltip-headerformat-and-pointformat-not-working-in-advancedformat-highchartsjs/

Cheers

Hi Preeti,

Since OutSystems uses Highcharts as its chart component, almost always you can check the Highcharts documentation to see if there's a way to do what you want (there's also plenty of examples).

You can put your formatting json in HighChartsJson which you can see after expanding the AdvancedFormat property.

 Hi @Preeti Mahajan 

You Can  Change the CSS of Tooltip in your Screen or Theme(module) .

Hi @Preeti Mahajan ,

You can try to input the color code manually like my example below

On the chart, use the AdvancedFormat_Init function of the OutsystemsCharts

Hope this help.

Thanks and best regards
