Sparkline Error with Combined Data in Looker Studio

Hi!

When utilizing the scorecard chart and enabling the "sparkline" feature as a comparative progress bar, it functions as expected with a standard dataset. However, attempting to create the same chart using a join through Looker Studio's combined data functionality results in an error. Could anyone clarify why this occurs? Is the sparkline feature incompatible with combined data sources?

Thanks!

You are right. This is a known bug when it comes to activating the sparkline line of a scorecard with blended data. The easier workaround would be to create a sparkline independent chart, below your scorecard. And so, do the same for all your scorecards to keep a design consistency across them.

I hope it helps.
