Is there a way to plot an implicit function ?


Im new to Cinderalla and Cindyscript, but I couldn't find an example of plotting an implicitly defined function.

Thanks,
Dennis

Dennis,

while there is no direct command to do implicit plots, you can use the colorplot function for this.

For example: if you have points A and B as upper right and lower left corner of the area where you want to see the plot, you can use the following script in the draw section to see an implicit plot of x^2 = y. See also the attached file.

colorplot( (1,0,0),alpha->(.5-abs(#.x^2 - #.y)), A, B, startres->8)


If this does help, I can create a CindyScript function that you can use to plot other equations.
