This is a macro for CorelDRAW 10/11 that allows you to enter parametric function formulae in the form of x=x(t) and y=y(t) and create the plot of the function right inside CorelDRAW document. Virtually every parameter of the plot is customizable - colors, fonts, outlines, axes, grid lines.
It supports over 30 standard functions such as sin, cos, exp, etc. as well as allows you to define your own with any number of arguments.
Live preview of the plot right in the dialog makes customizing the drawing a breeze.
