 Image Removed mcont  Image Added minput ( 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.
minput is used 2 define matrices as input for contouring or list of values as input of curve or symbol plotting. If the field is passed in array form, the user needs to describe how the array is to be mapped onto the subplot or geographical area which the array covers. | Info |

| With Magics, the concept of a 'FITTED' matrix no longer exists. The correct approach is to plot in a CARTESIAN projection and set input_field_initial_x, input_field_final_x, input_field_initial_y, input_field_final_y. |
When using the Magics Fortran interface, there is no need to call the action routine pinput. The input description has to be placed before the first call to pcont. (This is for backward compatibility with Magics6)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 |
