I'm very new to LaTeX.
I have read Is plotting exponential graphs a known source of bugs in TikZ? and implemented the code Jake supplied and this fixed the current problem. Thanks Jake :).
On this same page and in other forums people have mentioned a CVS install, should I take this step? I don't really know what it is as I use MikTex 2.9 and it says TikZ is current, yet my exponential graphs are the only one's that break. I am a math teacher/tutor and trying to use LaTeX for all my documents now, it's a big learning curve but the results are worth it. So will a CVS install be of greater benefit? And if so, how do I install this with the MikTeX Manager, or else wise.
