I have a chart where I like the default tooltips for the most part. The exception is the tooltip for the X Axis, which is just "X Axis". I have titled the Y Axis, and I noticed the default tooltip for that axis is its title, but I would prefer not to title the X Axis, which has custom self-explanatory labels. (That is, unless there's a way to title the axis but make the title invisible so the user doesn't see it, which would be OK.)
Most of the things I've seen that alter tooltips are intended just for the data points, or for the entire chart. Is there a way to change the tooltip only for the X Axis, without messing up all of the default tooltips everywhere else?
I am using an "Image" RenderFormat.
Thanks!
