My calculator won't graph anything and I've checked the windows and everything and it won't work. No matter what I type into y= i don't get graphs at all.

Turn calculator ON
If you see no icons, press Menu
Press 3 (Graph) draw your function. (more on that later).
If the first line of the display show Graph Func : Y= you should be able to draw your function.
If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.
After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.
Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

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.

You do not say if you get any error message.
Try to reset the calculator Press [2nd][+] to open memory management.
Press [7][RESET] followed by [1:All RAM] [2:Reset]
Then open the Y= editor and to the right of Y1= type in [X,T,theta,n] and press [ENTER]. You will see the straight line y=x.
Please report back what you get.

After entering the first function to graph press the down arrow and when the cursor blinks after Y2 type in the second function you wish to graph. After you finished entering multiple functions make sure the graph setting under the window button are set correctly so every function will be visible at the interval you set. After that you hit Graph and you should see your graphs being plotted.


I hope it helps.

Press the MENU key
Select 5:Graph and press EXE
In the Y= editor window, press F3:TYPE
Press F6 to access other graph types.
Select the inequality symbol you want and enter the right member of the inequality, then press EXE.
You are returned to the Y= screen.
When done entering your expressions to graph, press F6 Draw.

Press ZOOM 6 to reset the window range to their defaults. If that doesn't do it, please reply to this post specifying the exact function you're trying to graph and your window settings.

Having gone over a month without a response to my query, I assume it was a matter of the angular mode setting

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.

Press the 2nd key, the plus key and then 7, then 1, then 2. This will reset your calculator

This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.
