Hello, I was wondering if it was possible to "lock" one of your dimensions on a chart when using alternative dimensions? For example, let's say that I want a linechart with my X-Axis being Year to show trended data and a secondary dimension to show multiple lines. I want to be able to change my second dimension by adding alternative dimensions (e.g. Ethnicity, Gender, Title, etc.), but if I add alternative dimensions, then it gives the user the option to change the dimension being used for the X-Axis, which I do not want.
Basically, I want to have alternative dimensions, but lock one of my dimensions so that it can't be changed.
This is actually the solution that I am currently implementing, and it is a good solution, just not as ideal as being able to set the dimension individually for each chart. I really like how the alternative dimensions behave and I see that as the best method to handle changing dimensions, but if it isn't possible to affect only a single dimension then I will keep implementing the method we are currently using.
