My sister urgently needs this problem fixed.

When she enters data into the Y= menu, first of all there is a new symbol, kind of like a play button (a triangle) with a thick line right next to the point. When she presses enter to try and select the second line of data, the highlighted = sign is unhighlighted and the other line is highlighted. This means that her caluclator won't let her plot to lines on a graph.

Any ideas for assistance?

Re: Graphing Problem -URGENT-

The problem is causedby an application called "Inequalz".

To solve the problem, go to the Apps menu and select Inequalz,

then select "quit Inequalz".

This should solve the problem.

There is an application you executed previously. Its name Transfrm. Once executed it remains in memory and takes over the graphing duties. You must unload it from memory.

Press the Apps button; Scroll to find Transfrm; Higlight it and press Enter. In the new screen select the option that Uninstalls it. Do not worry it will not remove from the calculator.

The Transfrm application has been executed previously. It remains in RAM and takes over the graphing duties of the native OS. You must Uninstall Transfrm (that does not mean delete it, just unload it from memory).

To do so,

To do so,

- press the [APPS] button.
- Use arrow Up or Down (Up is faster) to reach Transfm.
- Select it and press [ENTER].
- In the new screen, select the number to the left of the Uninstall option.
- Go to draw your graphs. You will be able to draw up to 10 graphs.

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.

You can skip the next paragraph if you want

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.

Press the [Apps] key. Scroll down or up to reach the Transfm application. Select it and press [ENTER]. If that application was running you will see a new screen that tells you

Transfrm App

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.

To return your calculator's graphing equation to "Y=", press "MODE" from the home screen, then ensure that the option on the fourth row is set to "Func". Next, to show a hidden graph, access the Y= list, then press the left arrow key until the cursor is over the "=". Press "ENTER" to toggle visibility of that line.

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.

Hello,

Use the stat menu. Enter 1st member of a pair in List1, Enter 2nd member of pair in List2. Graph the data as a scatter plot in stats plots.

Hope it helps.

I am not quite sure what you are asking...

(1) if asking for graphing y= -2/3x+2, then press [diamond] [F1: Y=] type in .2/3x +2, see graph by [diamond][graph]

(2) if asking for graphing y= -2/3x+a, where a=3x, then first archive a=3x in Home screen by [home], type 3x [sto] a, then go back to y= menu, and type -2/3x+a in Y1

(3) if asking for graphing an equation that is dependent on 2 variables at the same time, use x-y-z axis (aka, change mode to graphing 3-D by [mode]graph [5:3D]) then enter desired equation in y= menu using Z function in terms of x and y aka z(x,y)= ...)

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:

In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.
