Why the dots in my combo chart are shown as a line chart???

But when I chose one filter this chart can show correct.

Please check this.

In your chart data point (dots) are connecting to each other due to axis range when you take single  expression you will see the difference.

Hi P M,

Do you know how to solve this problem???  Cause I cannot change the raw data, but I have to show this chart correctly.

Thanks in advance!
