2.4 Data plotting

Let me now show how to plot the data. MathGL generally has 2 types of plotting functions. Simple variant requires a single data array for plotting, other data (coordinates) are considered uniformly distributed in interval Min*Max. Second variant requires data arrays for all coordinates. It allows one to plot rather complex multivalent curves and surfaces (in case of parametric dependencies). Argument setting to default values allows one to plot data in standard form. Manual arguments setting gives possibility for fine tuning of colors, positions and view of graphics. Note, that the call of drawing function adds something to picture but does not clear the previous plots (as it does in Matlab). Another difference from Matlab is that all setup (like transparency, lightning, axis borders and so on) must be specified before plotting functions.
