Calculator Problem-Please help.

[kido_1]

I am using the Ti-84 calculator for spec maths and for some wicked reason when I try to graph more than one graph simultaneously, one of them automatically turns off(that is the line left of Y1/2/3/4... becomes unshaded).  

To the left of Y1/2/3/4 I don't seem to have the line, but some wierd dark thing...  :tickedoff:  :tickedoff:  :tickedoff:  :tickedoff:  :tickedoff:  :tickedoff:  :tickedoff:

I would appreciate any graphic techo's advice.

I use the TI-89 for spec and TI-84 for methods, works for me (maybe 'cause I love tech lol).

My best advice is to turn the black line to the left of Y1...0 to a normal line. It should solve some problems. If you have Inequalz or the inequality application installed, uninstall it for the time being. Also, what are your settings?

it should be:

CONNECTED
SEQUENTIAL.

Oh right, it seems to be working now, thanks.

No worries. The application usually causes these problems
