Back to School: Graphing Simple Functions

I was recently asked if there was a way to use Xojo Canvas Graphics to draw using the math X-Y coordinate system. First a little background. In Xojo (along with Java, .NET and many other languages), graphics are drawn where (0,0) is at the top left, X increases to the right and Y increases down. Other languages or APIs (Cocoa, for example) use a system where (0,0) is at the bottom left, X increases to the right and Y increases up.

WebChart, Easy as Pie

Among the many new features introduced by the Web Framework 2.0, one of my favourites is the new WebChart class. Based on Chart.js, this class offers a total of eight chart types you can create and use really easily in your projects; including the Line, Bar, Pie or Doughnut chart types among others.
