Re: Invalid Dimensions for Graphing and Equation
Hello, I suspect you are using the TINspire in TI84PLUS mode (with the TI84 keyboard). If that is the case, the simplest procedure is to turn off STATPLOTS. Press [2nd][STATPLOT] [4:PlotsOff][ENTER]. Calculator displays Done.

The Window parameters control the width and length of the graphing screen. The distance equation is a formula to use to calculate the distance between two points known by their coordinates. The window dimensions have nothing to do with calculations. Or maybe I don't understand the question.
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 then stat plot, and then select 4:PlotsOff. By the way it is easy to graphing function y=x^3-x^2-10x-8. See captured images: full graph and detail of the left side max
As you can see this function have zero values in the points -2, -1 and 4
This is problem with graphing differential equation. InvalidAxes error occurs if Axes=TIME or if t(time) is set as a CUSTOM axis. This is important to noticed: if Fields=DIRFLD you cannot plot a time axis. See captured image:
This graph represented differential system of equations y1'(x)=y2(x), y2'(x)=-y1(x) for initial conditions y1(0)=0, y2(0)=-1.Finally, x axes=y1(x) and y axes=y2(x)
Depending on the function you are drawing, it is possible that the graph is out of range of the windows dimensions. Try Zooming out to see a bigger portion of the plane. If you know where the function intercepts one of the axes, you might want to center the graph around that point.
1. To graph a function, Press [Y=] to enter the function editor. 2. Type in a legitimate function. 3. Press ENTER to validate the function. 4. Press the GRAPH key to draw the graph. 5. Play with the window dimensions or use the ZOOM feature to see more of the graph (or less).
Try your settings by drawing the function y= x If you have problem with Invalid Dimension or other errors, turn the Statistical Plots OFF. To do so, press [SHIFT] [Y=] to open the Stat Plots. Type in the number to the left of the Option PlotsOff. Then press ENTER.
You must deactivate the Statistical plots. Press [STAT]. In list that is displayed delect [4:PlotsOff] and press [ENTER] Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.
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.
It means that your Xmin or Xmax is messed up. it often shows up when you are plotting somethings (histogram for exanple) and you don't have enough X or Y range to fit all the points in it. it also happens when you are multiplying matricies without using the right dimensions. ERR:INVALID DIM just means your dimension is invalid.
