My TI-84 Plus will graph only one function at a time. Any suggestions?

• Kate1337 Mar 04, 2008

When I try to highlight another function under Y=, I cannot select the previous one. It will only allow me to graph one function at a time, same as everyone else ^

When you go to Y=, you should get a list that says:
Y1=
Y2=
Y3=
etc. You just enter the first equation into the Y1= space then hit ENTER and it will go to Y2=. Enter the second equation there. After you have entered all of your equations, push GRAPH and they should come up in order but they will all appear.

Also, make sure your window is set appropriately so that you are able to see all of the graphs.

Lastly, when you look at your Y= screen, are there funny looking arrows before the Y=? If so, do this:

• Press [APPS] key
• Select Transfrm from the menu
• Press 1:Uninstall

• Hope one of these are helpful!!

I've seen this many times before, when you are in the y editor, you should be able to change the graphing from line to dot, to shad, etc. instead it is set on setting which can't be changed to correct this, reset the calculator, if you have programs on it, transfer them to a different calculator, this should correct the problem, I have had it many times before, don't know why it sometimes happens but resetting the system will work, go to memory and you will find reset

### How to graph 2 lines at once

ok well go to the 'y=' button
type in the equation and make sure that the equals sign after y has like a black box around it, making the actual = white. so make sure both of those = signs of the 2 equations that you want to graph are like that, and thats about it.

### Getting more than 10 equations into y=

The TI 83, 84 seris can not store more than 10 equations. the TI 86 and above can have infinate, but not the 83, 84s. If you have catalog help in your apps, you can run that, and it will be able to tell you all the syntax of every function it has.

### Graphing

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.
• Press [APPS] key
• Select Transfrm from the menu
• Press 1:Uninstall
