Extension --> Render --> function plotter in tab Range and sampling.

If the Start X value is the same like End X value the program gets an zero divison error. Fortunately the program don't crash.

Reproduced with Inkscape 0.48.3.1 and 0.48+devel r11772 on OS X 10.7.4

attached is a modified version of funcplot.py. It can be tested by copying it into the folder \share\extensions\. It will raise a warning message if either the x- or y- intervals are zero.

since this contains new text and since we are in frost and translations are being committed, I won't do anything with this until receiving approval to go ahead.

the file is working, Thank you Alvin.

Could I translate the sentence to Germany or is the warning message coded in the py file?

@Alvin - Strings can be changed until we reach hard freeze (November 23, 2012). Feel free to commit now.

@Uwe - The error message is coded in the extension, and will be available for translation as soon as the python file is in the trunk and the inkscape.pot file is updated.
