I'm making an app for a university project, and I can't understand the manipulation of curves in xojo. I need a form where there are 4 sliders and each one handles the height in a gaussian bell independent of each other (it can also be a quadratic function).
The background must have the spectrum of visible light. and the 4 levels must be a single curve on the image that indicates the approximate value set with the sliders.
If you think you can do the form, talk to me and I'll explain better, with images, etc.
