I have created a confidence vs. competence chart using Report Builder 3.0. Currently the "cross section" of the chart is static and separated by a background image on the chart.
Like this:

However, as a requirement, the cross section needs to be dynamic. I can remove the background image (it isn't needed). I can pass the values for the both the x and y axis into the report when the lines need to cross. The problem is trying to actually implement this on the chart.

Can anyone provide a solution or point me in the right direction?
