My calc doesn't graph. Once I click graph it says ERR: Invalid Dim, and my only option is Quit. What do I do??

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If this doesn't do it, please reply to this post and give an example of something you're trying to graph.

If this doesn't do it, could you post the exact function you're trying to graph?

INVALID DIM • The ERR:INVALID DIM error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots. To turn the stat plots off, press y , and then select 4:PlotsOff. • You specified a list dimension as something other than an integer between 1 and 999. • You specified a matrix dimension as something other than an integer between 1 and 99. • You attempted to invert a matrix that is not square.

If you are in the stat mode and entering points in list 1 and list 2, it could be that one list is longer than the other.

If you are just trying to graph from the y= screen, one of your plots is probably turned on. The easiest way to fix this is to press the 2nd button the the plus button, then 7 and then 1 and then 2. This will reset to factory settings.

Go to your stat plot screen, and select option 4 (PlotsOff), Press Enter, and try to plot a normal graph again
