Currently there seems to be no way to change major and minor unit changes for ValueAxis (similar to HSSFCahrt.setValueRange(int axisIndex, java.lang.Double minimum, java.lang.Double maximum, java.lang.Double majorUnit, java.lang.Double minorUnit).
Any chance you could write up a small patch to add this in? Bonus marks if you can do a unit test for it too!

I would like to provide small patches or enhancement in future once i get time to go through open XML format and code base. (esp. i would look into the feasibility of adding column chart from the scratch).
