ERR: INVALID DIM (That's the error message I receive every time I try to graph an equation)

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 2nd, STAT PLOT , and
then select 4:PlotsOff.

As you can see this function have zero values in the points -2, -1 and 4

Go to http://education.ti.com/downloads/guidebooks/graphing/84p/TI84Plus_guidebook_EN.pdf to download the manual. On page 401, you will find the following:
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 the message appears when you try to graph functions deactivate the statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)
Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.If the message appears in another context, it sure would help knowing the context of the error.

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.

Hello,
The easiest and quickest way to start graphing is to reset the RAM. Press [2nd][MEM][7:Reset][1:All Ram][2:Reset], then [CLEAR] to clear the RAM Cleared Message and go to the main screen.
Hope it helps.

Hello,
Here is what the manual says
INVALID DIM : The dimension of the argument is incompatible with th current operation. (As dimension of a matrix, a list).

You can tell us more about what your were trying to do, we may able to help. Reset memory to default, the error may disappear.
[2nd][MEM][7][2][2] Defaults set.

Hope it helps.

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.
