Just passing by, make sure you aren't zoomed in or panned away from the axis when you look. Check to see if there is some way you could be referencing a matrix. I can pull up a similar error by trying to pull a value out of a non-existant slot. I got my first TI 2 days ago, so I probably don't know as much as you.

INVALID DIM â€¢ 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. â€¢ You specified a list dimension as something other than an integer between 1 and 999. â€¢ You specified a matrix dimension as something other than an integer between 1 and 99. â€¢ You attempted to invert a matrix that is not square.

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

You have to turn all statistical plots OFF before you draw function graphs. Press [2nd][Y=] to open the statistical plot configuration screen. Press [4:PlotsOFF] and then [ENTER]. When calculator answers DONE you are ready to draw function plots.

You have two lists that don't agree in length.

Solution 1 (easy)

Press [y=] and look at the top line - one of your Plots is highlighted.

Move the arrow to the highlighted one, press enter to get it un-highlighted.

Solution 2 (permanent)

Press [STAT] - EDIT: [1] to edit your lists. Go to the bottom of the lists and see which one is the longest. Delete (DELETE, not clear) the "extra" entries in the longest list until all lists are the same length.

This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.

If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.

Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.

I think you are saying that when you graph, you get the message "invalid dim"

If you are trying to graph from the y= screen it may me that you have one of the plots on. If this is the case, look at the top of the y= screen. If plot 1, plot 2 or plot 3 has darkened box around it, the plot is on and you need to turn it off. Move your cursor on top of the one that is highlighted and press enter. You should now have the plot turned off and should be able to graph from the y= screen.

Another way to do this is to press 2nd key, plus key and then 7, and then 1 and then 2. This will reset your ram.

This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.

on a calc that's work properly, in the 'y=' screen, none of the 'Plot#' things are highlighted. try pressing 'y=', and if you have a 'Plot#" in a black box, go up to it and press enter to un-highlight it.

either it will work as soon as you press 'graph',or you have another problem
