I have the code below which I have run before without problems but I suddenly get the error message "Error using stackedplot (line 100)
Invalid or deleted object." at the line "stackedplot(acctable,{'accX','accY','accZ'})". Can anyone help with this?

That error tends to occur if an axes gets deleted out from underneath you. subplot() can cause existing axes to be deleted, in the circumstance that the new axes overlaps an existing subplot without being exactly the same size.
When I look at your subplot() calls, everything looks okay to me: the only way at the moment that I could see the problem happening is if you happened to click on something while drawing was happening... in which case the "current" axes could change without notice.
You can reduce the possibilities of that happening by always expliciitly specifying the parent of graphics calls.
I do have a concern in the below: geoplot() needs a geoaxes, and I am not certain that it will play nicely with the subplot()
