How can I produce a contour plot from two-dimensional non-gridded data?
First you need to get your data in gridded format. You can do this using one of your own interpolation routines, or you can use one of the gridding routines in the Ngmath package. Once you have gridded data, you can create your contour plot using Conpack. • How can I get three-dimensional non-gridded data into gridded format? You use one of the gridding routines in the Dsgrid section of the Ngmath package. See the URL: http://www.ncarg.ucar.edu/ngmath/dsgrid/dshome.html To see some examples using Dsgrid, type: ncargex nnex03 c_nnex03 NCAR Graphics programs • I want to write an NCAR Graphics program, but would prefer not to start from scratch. Are there any examples available? Yes, you can use the application ncargex. Appendix D of the NCAR Graphics Fundamentals contains a pictorial guide to most of the examples that you can then access with ncargex. • How can I get a list of all the examples available for a particular utility? Type: ncargex -xxxx -list where xxxx is the name of a parti
