How can I show a single trendline for multiple chart series?

[Tim Gorgs]

Hello Syncfusion team,

I'd like to be able to show a single trendline for multiple series in a chart. My use case is to display financial amounts of different categories per month in a stacked bar chart (this works fine). Now I'd like to have a trendline for the combined monthly amount instead of one trendline for each category of the stacked bar chart being shown. To illustrate my issue please have a look at the supplied image below:

Is there any way to achive what I want? Thank you &

Kind regards

Tim

Hi Tim, 

  

Thanks for contacting Syncfusion Support. 

  

Currently, we don’t have direct support for displaying single trend line for multiple series. However, your requirement can be achieved by using another series with trendline. 

  

We have prepared a demo sample for your requirement and it can be downloaded from below link, 

  

Sample: Trendline
