I try to modify your function by start t-value = 0 and end t-value =6.28, but do not success. Very very beautiful butterfly.

My mistake was to assume that there were no spaces in the formula(?). is there a rule for putting spaces in so I can check before setting things in motion? beautiful! thanks!

As I mentioned above, the first time I tried it I had a problem because I'd not selected a rectangle first, but that didn't cause a syntax error. Maybe you have a typo. Try copying and pasting the following: <code>sin(t)*(exp(cos(t)) - 2*cos(4*t) - pow(sin(t/12), 5))</code> <code>cos(t)*(exp(cos(t)) - 2*cos(4*t) - pow(sin(t/12), 5))</code> Kevin: I just repeated the example in the screen shot and it worked for me.

I'm following the image of the dialogue but I'm getting a syntax error. Any idea what could be happening (apart from a typo)? Hi John

Then I open that file with inkscape and edit it to make it visually pleasing. For data plots I tend to produce a basic plot with gnumeric or similar, and export the plot as an svg file.

The function plotting extension is essentially a Python interpreter. There may be a way to have it call Python code that gives it your data.
