Setting Dual Y-Axis on Line Chart with Multi-Select Parameter

Hi Experts,

I'm currently working on a line chart that utilizes a parameter with multiple measures:

• Total Sales
• Total QTY
• Total Profit
• Total Discount

When selecting multiple parameters, such as Total Sales and Total Discount, I encounter an issue where the Total Discount values, being significantly lower, are not distinctly visible and are displayed as "0K" on the data labels.

To address this, I attempted to implement a dual Y-axis specifically for Total Discount.
However, this led to the line charts being duplicated instead of just adding a second Y-axis for the Total Discount.

Could anyone provide guidance on how to correctly set up a dual Y-axis for Total Discount in this scenario without duplicating the line charts?

Thank you!
