New in 2.20
A contour_line_colour_rainbow parameter has been introduced, allowing the user to specify a different colour for each isoline.There are 2 ways to specify the list of colours to use, the setting being very similar of the colour settings for shading:define the list, or let Magics computes the list given a max and min colour.
contour_line_colour_rainbow mcont(contour_level_selection_type = "interval", contour_line_colour_rainbow_max_level_colour = "red", contour_line_colour_rainbow = "on", contour_highlight = "off", contour_line_colour_rainbow_direction = "clockwise", contour_line_colour_rainbow_min_level_colour = "blue", contour_line_colour_rainbow_method = "calculate", contour_interval = 1.00)

A contour_automatic_setting parameter has also been introduced, if set to ecchart, Magics will try to match the parameter with one of the predefined ecChart style.
contour_automatic_setting mcont(contour_automatic_setting = "ecchart")

mcont ( macro/python ) pcont ( fortran )
Contouring is achieved by calling the action routine pcont, i.e. call pcont . The call may be preceded by one or more calls to Magics parameter setting routines. pcont will only take into account those parameters set before the routine is called. Any calls to Magics parameter setting routines after pcont is called are only relevant to future action routines.
When the action routine pcont is called, it will plot contours based on the input data supplied and according to the user's instructions. The input data may have different organizations: GRIB code data, regular latitude/longitude grid, gaussian grid. Before pcont is called, the user must define how he wants the data to be contoured, i.e. location of the data, dimensions of the array, input field organization etc. This is done by calling Magics parameter setting routines. Data may be passed in an array, in GRIB or NetCDF format
