TI-Nspire customer service can't me help on this matter so if you know of how to fix my problem please respond.

Whenever I graph equations and measure coordinates using the TI-Nspire software my graph is plotted with the equations and coordinates shown overly large. It doesn't take me long before viewing a whole load of oversized values smothering the graph/s I am trying to see. I know they are too large because I have seen them at some smaller unobtrusive value.

I have no means of changing fonts size in graphs. My question is this. How is it that I have worked in graphs with equations and coordinates shown with adequate size only to find that some event changes the status quo to the one I've described below. What is going on?

Any help would be, well, helpful.
