Hi prof

i want to make the applet always show equal size for x and y axes for the reason that circle will look like circle instead of an eclipse.

any tips how to do it??

i try changing the PlottingFrame Size to a variable name "size",

i try making a checkbox to action a function say called showsum()  {actually i instead to equalaxes} ;D

and i added a custom function

but it didn't work.

chance to tip me on the easiest way to mqke a checkbox that when checked will make the PlottingFrame Size equal ?
