environment axis undefined; compilation error

[GoogleCodeExporter]

What steps will reproduce the problem?
1.generate a random matlab plot
2.use matlab2tikz.m to generate a tikz file
3.open it with the tikzedt

What is the expected output? What do you see instead?

For compilation problems: What is the error pdflatex reports? You find the
latex output in the textbox at the bottom of the TikzEdt main window. (You
can switch between Status/Latex output/Error list.)

Editor Error: "Environment axis undefined. \begin{axis} (followed by: [%)"

What operating system and Latex distribution (Miktex/Texlive) are you
using?
Windows 7; TeXworks

Please provide any additional information below.
I tried several editors, like QTikZ eg. and had exactly the same problem.

axis needs the pgfplots package, which is not by default included in the 
tikzedt preamble. (Maybe I should change that for the next version.)

Any, you have to go to settings->Settings->Compiler
Then add
\usepackage{pgfplots}
Close the settings window and click
Compilation ->Regenerate precompiled headers.

Then press F5 to refresh the view.

if i do so it leads to another error and a warning

error: Undefined control sequence: \end{axis}
warning: running in backwards compatibility mode (unsuitable tick labels; 
missing features). Consider writing \pgfplotset{compat=1.7} into your preamble.

adding \pgfplotset{compat=1.7} removed the warning; but the error remains

Can you send the Tikz code? I tried with the following, and it worked fine:

now i see. i used some given codeexample for the matlab2tikz in the following 
form:
matlab2tikz('sigmoid_test', 'height', '\figureheight', 'width', '\figurewidth')

this lead to the attached tikz-code with the dimensions \figureheight and 
\figurewidth.
excuse me, thats a quite naive mistake. so its working now by setting these two 
to actual values.
thank you alot for you time. also for this great software:)
