Error in graph

Hi

I must have done something wrong in the graph function, because now I can´t draw any graphs. I only get the message 'ERROR: window variables domain' when I try.

Help?

I have the same error. Helping my 16 year old graph a log function. I went to the Texas Instruments web site, typed in "windows variables domain" in the support area and they will walk you through correcting the issue. Eric

How can i draw graph.


This should help you setup your calculator to do graphing.

1. Prepare calculator for graphing
Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

8e1f66f.jpg
2. Setup Graph type
  • Press [MODE] key.
  • In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
  • Use the arrows to move cursor to 3rd line to highlight degree or radian and press [ENTER]. The important thing is that you be aware of the unit so that you do not get unexpected results.
  • On same screen, verify that Func is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list
  • If it is not, use arrow to highlight Func and press [ENTER] to validate.
  • Do not worry if you do not have exactly the same screen as in the screen picture (We may have different OS Versions)
142a378.jpg

3. Entering the functions to draw (assuming you want to draw y= functions)
  • Press [Y=] to enter function editor.
  • Type in a function
  • Press [ENTER] at the end of each function.
  • Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
  • In the screen capture 4 functions are slated to be drawn.
3301a18.jpg

4. Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)
  • Select the graph style: The small piece of line to the left of a Y that defines a function is the style.
  • Move cursor on it and press [ENTER] .
  • Each [ENTER] (on same line) selects another style.
  • On the next screen you have all the styles available on the calculator.
  • Do not select the bubble on line 6: It is for animations. It will not leave a trace at the end of the plot.

5. Drawing the Graphs
  • Press [GRAPH] to see the graphs.
  • If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
  • Here are the dimensions of the standard window

When I try to graph, I get ERR:INVALID DIM I tried going to PlotsOff and I still can not graph


What happened when you tried going to PlotsOff. Did you actually execute the command?

If you executed that command and cannot graph then for some reason you are feeding lists or matrices as arguments to the functions you want to draw.
By the way are you drawing STATISTICAL GRAPHS or FUNCTION GRAPHS?

If you are drawing statistical graphs and you executed the PlotsOff command, it is normal you will not be able to graph because PlotsOff turns OFF the statistical graphs.

Here are a few things you can do:

If you got the message while trying to draw a graph
  1. Press [2nd][Y=] (STAT PLOT)
  2. Choose option [4:PlotsOff][ENTER]. Screen displays Done
If message popped up while doing something else that involves lists or matrices, the length of lists may be different, or the dimensions of matrices may not be compatible.

To Clear the lists:
  1. Press [2nd][0] (CATALOG)
  2. Press [PGRM] (C) to jump to first command that starts with c.
  3. Use arrow to scroll down to ClrAllLists, select it [ENTER]
  4. Calculator displays Done
  5. Start the new problem.
To reset the Ram press [2nd][+] (MEM) [7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the Ram Cleared message.

I tried to draw a graph manually but I kept getting an error message even thoug I did it step by step like the users guide instructions said


Error messages are important to help solve the problem.
Try the following instructions to draw the function Y=5X+2
but first Reset the calculator by pressing the RESET button on back of calculator. I do not want you to run into problems created by old settings.
  1. Turn calculator ON. If you do not see several icons press [MENU].
  2. Use arrow to select the [GRAPH] application and press [EXE].
  3. In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
  4. Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
  5. At the position of the cursor type 5 then press the [X, theta,T] key, under the [ALPHA]. On the screen appears 5X, complete your equation by typing [+] 2
  6. Press [EXE] to store function.
  7. If you want to draw other functions, it is time to do so on that screen.
  8. When done, press [F6:Draw].
  9. If the screen does not show a lot of the function, you can use the arrow keys to pan (move the center of the graph. You can pan Up, Down, Left, or Right.
  10. You can also press [SHIFT][V-Window] to set the window limits.

Won't graph two functions


A) IF YOU GET AN ERROR MESSAGE,

it might be worthwhile to let us know its contents. If you do get a message ( INVALID DIM) you should turn the statistical plots OFF.
To turn statistical plots off
  1. Press [2nd][Y=] to open the (STAT PLOT) menu.
  2. Select [4:PlotsOff] and
  3. Press [ENTER].
  4. Calculator displays Done
  5. Restart your graphs.
  6. Adjust the window dimensions if necessary or use the ZOOM function to have all graphs displayed.

B) IF YOU DO NOT GET AN ERROR MESSAGE

Usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.
The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must Uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

  1. Press the [Apps] key.
  2. Scroll down or up to reach the Transfmapplication.
  3. Select it and press [ENTER].
  4. If that application was running you will see a new screen that tells you some thing like
    • Transfrm App
    • 1:Uninstall
    • 2:Continue

    Press1:Uninstall.
    Graphing functionalities will revert to the native OS

Another potential culprit is the Inequalz App. To Uninstall it, do as for the Transfm and select the option that will unload it from memory.

How do I graph on the T1 83 plus when an invalid


Hello,
You must have done some statistical calculations. This type of calculations activates the statistical plots. The resulting configuration conflicts with the normal graph configuration.
Before drawing function graphs, you must turn off the statplots:
Press [2nd][Y=] to access (STATPLOT)
Press [4:PlotsOff][ENTER][ENTER] Calculator displays Done.

Then you press [2nd][0] to access the (CATALOG) of commands. Then [PGRM] to enter the letter [C]. Cursor jumps to the first command that starts with the letter c (omitting the Greek symbols). From there, scroll a bit to highlight [ClrAllLists] and press [ENTER][ENTER]. After clearing the lists the calculator displays Done.

You should be able to draw your graphs.
If that does not work, just reset the Ram as described below.
Press [2nd][+] to access (MEM)
Press [7:Reset][1:All Ram][2:Reset].
Press [CLEAR] to erase the Ram Cleared message.

Press [Y=] and enter your functions. Press [ENTER] at the end of each function. Make sure each [=] after Y1, Y2, remains highlighted after the cursor moves to some other location.

Hope it helps.

My graphing calculator only allows me to graph one line at a time


Hello,
Once you enter an equation the corresponding equal sign is highlighted by default. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted. If one is not highlighted, move the cursor on it and press ENTER.

Once all the = signs for all the functions ypu want to draw are highlighted permanently, press the [GRAPH] key.
Depending on the functions ane the window dimensions certain graphs may not show up and one can Zoom out or adjust the window.

If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER]
Command PlotsOff echoes on main screen. Press [ENTER], screen displays Done.

If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You shouild make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.
