There are Dyn CRM classic bar chart diagramms with more than one value in the x-axes defined (maximum is 4). The are always in the same unit. See example attached. Microsoft is not be abled to visualize this correctly. The is always a 2nd vertical axes with a different measure unit. This confused all the users.

Expectation: Display in this case only one vertical axes with the right scale. And provide a flag to switch between your behavior.

Many Vertical Axes = yes: Display for every value on the the x-axe a vertical axes

Many Vertical Axes = no, Display only on scale on the vertical axes with the correct values (like Power BI and other tools)

We can attach further examples
