Hello,
1.Press [MODE], scroll to set Function graphing mode.
2.Press [STAT] [5:SetUpEditor], command is pasted in home screen. Press [ENTER]. Screen displays Done. This clears old values in lists

3. Press [STAT][1:Edit] to enter data.
Press [ENTER] after each number. Cursor moves to next row. After finishing the data of Listt L1, use arrow right and UP to the head of list L2. Enter the values in list L2. Press Enter after last element.

4. Press [Y=] to display Y= editor. Clear function Y1 and all functions or remove highlight from the = in Y2, Y3, etc.
5.Press [2nd][STATPLOT]1 to select 1:Plot1

The blinking cursor on ON means graph will be drawn. Type chosen is Scatter plot. Mark chosen is a dot.

Press [ZOOM][9:ZoomStat]

If you think that the curve look like a straight line you can try to do a linear regression.
Press [STAT] Arrow right to highlight [CALC]

LinReg(ax+b) echoes on run screen. Press [2nd] L1 Press comma, Press [2nd] L2 prHow do I use stat plot to graph a set of points? - 68a28f1.jpgress [VARS] Arrow right to select [Y:VAHow do I use stat plot to graph a set of points? - ff52832.jpgion] [ENTER][1:Y1]

ENTER

That is the equation for the linear regression. As you see eqaution has been saved in Y1. Press [GRAPH] to get the data and the regression curve drawn on same graph.

Hope it helps.

### I can't graph anything

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.

### So on my graphing calculator i put my equation x^3-x^2-10x-8. then i hit graph and it says err:invalid DIM.

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

### When i click graph it says "ERR: INVALID DIM" i noticed under "y equal" mode that plot 1 and plot 2 are highlighted. how do i fix this, i need to be able to graph. TI-84 plus calc.

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.

### I'm graphing a quadratic equation, I have all my info put into the stat area and nothing in the Y= area. When I graph it the points are small boxes, there is no graph line and it won't allow me to do any...

If you're doing a stat plot, you're plotting a discrete set of points. The calculator doesn't interpolate between the data points.

If you want to graph a quadratic equation, then do so. Enter it in as a Y= equation and plot it as such. This will not only connect the points (unless you tell it not to), but will also allow you to do things like trace.

### My calc doesn't graph. Once I click graph it says ERR: Invalid Dim, and my only option is Quit. What do I do??

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 this isn't the problem, try posting the function(s) you're trying to graph, as well as the window settings.

### Graphing problems

Hi,
From what I understand you want to draw statistical graphs (scatter plot, box plot, etc.) and you window is set up correctly. Usually, one must first see agraph and adjust the window, but no matter.
If you do not see anything it may be due to the fact thea the statistical plots are turned off.

Type in the data in lists L1 and L2, etc. Press [2nd][QUIT]

Press [2nd][Y=] (STAT PLOT] . Select [4:PlotsOff] [ENTER] .
Screen displays Done

Press [2nd][Y=] (STAT PLOT] . Select [1:Plot1 Off].
1. The configuration screen for Plot1 opens with the cursor blinking ON.
2. Press [ENTER] to turn Plot1 ON.
3. Use Down Arrow to move cursor to second line Type:
4. Select the type of statistical plot. Use the right arrow to move highlight on one of the 6 types.
5. Select the type:scatter, Xline, histogram, box plot, and press [ENTER] to validate the choisce.
6. Use down arrow to select the Xlist: use [2nd][1] to choose L1, etc. and press [ENTER]
7. Select the Y-List (L2) and validate by pressing [ENTER]
8. Select the data-point mark.
9. Press [GRAPH].
If you do not see the graph or if it is not well centered, press [ZOOM][9:ZoomStat] to restrict the screen to the data entered.

Hope it helps.
Thank you for rating the solution.

### Graphing

Press STAT, go to Edit, then enter x values in L1 and y values in L2 (other lists can be used too, but these are the default ones).

Next, go to STAT PLOT, pick a plot, turn it on, select the type, data lists (x and y should be L! and L2 already; if not, change them), and mark type.

Finally, hit graph. You may need to adjust window settings to see all of the points. If you get a DIM MISMATCH error, check to make sure that there are the same number of entries in each list, and that only the plots that you are using are turned on.

### INVALID DIM

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
