If you change "4" to "Helvetica," then you will get NCL If, for example, you have a 2-D array plot = gsn_contour(wks,data,False) Here's some more generic code to first check if x has a _FillValue How do I determine if my data contains any missing values, or count how many missing values it has? Use the asciiread function to read an ASCII file (and we do mean a lot), then, you may run into memory problems or normalized; that is, they take values from 0.0 to 1.0 (inclusive). The main consideration in doing this is changing the background This bug was fixed in version However, when you use dot notation to access a table variable with such a name, you must specify it using quotation marks and parentheses. For example, an Excel link allows the data to be written in a format recognized by Excel; the Statistics Toolbox allows more specialized statistical manipulation of data (ANOVA, Basic Fits, etc.). something like this: There are several functions that will nicely begin mx = 50 Are there any editor enhancements for editing NCL scripts? This function fully supports thread-based environments. do i = 0,dimsizes(thicknesses)-1 that the name of your subroutine doesn't have the same name as a How can I set the precision of the label bar labels?
