notes:
- my program doesn't run background threads cause this.
- fitting plots after pinching graph zoom causes crash around third of time while fitting plots when app has been idle time causes crash.
- it doesn't crash on simulator. device.
is known bug coreplot? appreciated.
edit: app sets global x , y range of plot space nil before calling scaletofitplots: (so can fit plots outside current global range). when remove this, app no longer crashes.
is bug coreplot? how work around this? (i still need limit user zooming pinch gestures)
upgrade core plot 0.4.
i no longer crash after upgraded 0.4. http://code.google.com/p/core-plot/downloads/list?can=2&q=&sort=-uploaded&colspec=filename%20summary%20uploaded%20releasedate%20size%20downloadcount
