Well it seems that you are graphing stat points and forgot to turn them off. This can be easily fixed by going to 2nd and Stat Plot then make sure all the stat plots are turned off. This should solve your issue.

My TI-83 Plus calculator won't graph anything whatsoever. Did I need new software. Please help me.


First - Are you graphing within the proper window? Hit the zoom button and change it to zoom Standard within the graphing window.

Second - Are you inputting the equation correctly? Make sure you are inputting your equations in a y= format. If possible, please reply with a screenshot of your graph screen.

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

My TI-84 Plus Silver Edition Graphing Calculator continues to read "ERR: INVALID DIM" whenever I attempt to graph equations.


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 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.

No Y's in Table


The tables will not say Y specifically, they only say L1, L2, L3, etc. UNLESS you type in an equation in the "Y=" button menu. When you type an equation in on that page, and then hit "2nd" "GRAPH", you will get X and Y values for that equation.

Graph feature not working on my TI-83 Plus


Simple:

Hit this sequence:

"ZOOM" "0"

That is for the "Zoom Fit" option. The calculator does not like the window you have for the equation you've given it. With this option, it will automatically give you the best fit in the window for the equation!

Graph feature is not working on TI-83


you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck
