I have tried the usual tricks and feel I must be missing something obvious.....
Update: Discovered that AreLabelsVisible="False" AreMinorTicksVisible="False" AreMajorTicksVisible="false" works for XYDoubleAxis, but not for XYDecimalAxis....
Still would like a means to swap in my own axis if possible, otherwise I can hide the XYDoubleAxis as per above and put my axis in below, but will need to inspect visual tree to size/position properly.
Update #2: Successfully injected my own axes, so no help needed :)
