When I graph a function on my TI-89, the ticks on the X line, and the Y line have vanished. I have my xscl and yscl values both set at 1 and it still does this. I don't want the grid on the screen, I know how to display that. I just want the X and Y lines with the ticks back...... Help! Please e-mail me.... Thanks! Joe capasso@cyberenet.net
