There is no one good window range for all graphs, since graphs can have different areas of interest.

Press the ZOOM key, then select ZStandard. This will restore the window settings to the default range, which will at least allow the graph to be displayed. You can then change the window range and/or zoom as desired.

If this doesn't do it, please reply to this post, giving the function(s) you're trying to graph and your current window settings.

I have the TI-84 Plus calculator and when i try to graph anything, it says ERR: WINDOW RANGE. What do i do?

Press WINDOW (the second key on the row of function keys at the top of the keyboard) and check your settings. Alternatively, if you're plotting a function press ZOOM 6 to set the standard window range and if you're plotting data press ZOOM 9 to set the range to go with the data.

Calculator all of a sudden stop graphing. When i hit graph it says err:window range

Press the WINDOW button (2nd from the left, very top row) and check the window limits. In particular, make sure that Xmin and Ymin are less than Xmax and Ymax respectively.

If that's not the problem, append a comment to this post listing the window variables and the function you're trying to plot.

I can't graph on my ti-84 plus silv. edition

More than likely, you've put in a number in the xmin or xmax that is not correct. put in an xmin of 10 and an xmax of -10 which would be backwards. This could also happen in the ymin or y max.

The easiest way to fix this is to press zoom 6 which wil get you back to the default graph of xmin of -10, xmax of 10 and ymin of -10 and y max of 10.

If you can't see your graph on this screen and need to change the window, just be sure the number in the min for both x & y is smaller than the number in the max. You change your window size by pressing the window button.

My Graphing calculator has no x or y axis. Its all Blank.

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

"Err: Data Type" - Not Allowing Me to Graph

First, turn it on. Once the calculator is on, press the "2ND" key (I believe it is a blue key in the ti-84 plus silver edition). Now press the plus key (+). A little above that key, you should see the word "mem." When you see the screen titled MEMORY, move the cursor all the way down to the option that says "Reset." From here, you can choose to reset either the RAM memory, or the factory settings. The factory settings are the "Defaults" option. I hope this helps.
