This project is going to be somewhat like a graphing calculator. However, it will likely not support functions that don't have x as the subject or solving. You can pan the canvas using the arrow keys and zoom in and out using the buttons. You can use the 'Point Density' slider to increase the number of points the equation is run at. The higher the number, the better the line looks, but it takes longer to render To edit the equation of the graph click the 'Show Expr' button to show the current equation. To edit the equation use Scratch's builtin list controls. To draw the equation click the 'Redraw' button. The equation is in Reverse Polish Notation, which means that the operator comes last (eg. 4 + 5*9 is 5 9 * 4 +). The currently supported operations are: * +, / and * * sin (in degrees) * x - pushes the current x coordinate onto the stack Any values left on the stack at the end of the equation will be drawn to the screen.
Changelog: * v1.0 - Added the ability to edit the expression * v0.3 - Added the ability to draw multiple lines * v0.2 - Fixed an issue where the line wasn't drawn at all points * v0.1 - Initial Release Features I'm intending to add: * Non-RPN equation input. * More operators * Tracer * More????
