Trend/Line charts in Chart template

HI ​@Frederic Fery 

thanks for reaching out! If you’d like to keep using the dummy data pane, your best option is to:

• Add a manual line shape over the chart and group it with the chart.

There isn’t a built-in trend line toggle at the moment. If this is something you’d like to see in the future, I’d recommend adding it to the Wish List post so the product team can track the demand.

Hi, trend lines are not natively supported in most chart templates, so there isn’t a direct toggle for them. A common workaround is to add an additional data series that represents the trend line and style it differently so it appears as a smooth line over your main data. You can generate the trend values manually in your dummy data pane and use that as the second series.
