Can you attach workbook?
I doubt if this is available the way you expect it.
The quick thought from my end is,
1. create calculated field = Field1+Field 2
Apply this field on color mark and manually select Hues for Each Field1 with Gradients on Field2
For such approach, you may have to create custom color palette.
2. Hue and gradient is somewhat available in dual axis charts.
1. First Axis to set hues based on discrete data
2. Second axis to set gradient based on measures
play with the opacity to get desired effect.
Yes - similar to that Rahul. How did you achieve it?
You can select two dimesion by holding the Ctrl keys and then place them together in the Colours mark. You can then move the colour dimensions up or down with respect to each other to get the view that you want.
Attached is the gif image for reference .
Do let me know if this helps.
