How to Create a Combo Chart with Stacked Bars and a Line in Looker Studio

[Vinny_Alba]

I am trying to create a combo chart in Looker Studio with the following setup:

• Columns in my dataset:

  • D (Date) – X-axis

  • V (Numerical value) – Y-axis

  • L (Category) – Breakdown dimension

I want to achieve the following:

1. The bars should be stacked by L and display the sum of V.

2. The line should plot the same V values so that at each date (D), the height of the line matches the total height of the stacked bars.

3. The X-axis should be based on D (Date).

How can I configure the chart so that the line correctly represents the sum of the stacked bars at each date?

Any help would be greatly appreciated!

This should be possible! One way to get at this is to create a calculated field that sums V for all L. Then you can make this new field a line while the rest are stacked bars.
