I need to plot multiple series on the same chart where there is one common y-axis, but each plot needs its own x-axis since they each have their own x scale (i.e. all have different min max values in the x-axis). The only way I've managed to accomplish this is to add an x-axis per series and associate the series with the correct axis. This is essentially working the way I want except that I have some pretty specific x-axis formatting requirements that I will probably implement in a separate UIView.
In order to do this I would like to hide all x-axes. Currently, no matter what I do there is a always vertical space allocated by the chart which has the undesired effect of shrinking the plot area. Here is what the chart currently looks like:
