Plotting

AXIS - Draws an axis of the specified type and scale. (Direct Graphics)

BARPLOT - Plots data as a series of rectangular bars.

BAR_PLOT Procedure - Creates a bar graph. (Direct Graphics)

ERRORPLOT - Draws a line plot, with error bars surrounding each vertex.

ERRPLOT Procedure - Plots error bars over a previously drawn plot. (Direct Graphics)

IDLgrAxis - Displays a plot axis object that may include tick marks, text and a title.

IDLgrContour - Draws a contour plot from data stored in a rectangular array or from a set of unstructured points.
