set stat

set stat on | off

If on, GrADS will print statistical output to the terminal every time the display command is executed. The statistical information is the same as that which is output with set gxout stat.

Usage Notes

1. If you "set stat on", GrADS will continue to display the output statistics with every display until you "set stat off".

2. Use this command if you are overlaying plots and want to guarantee that the 2nd plot will be drawn with the same range of values. See example #2.

Examples

1. Here is an example of the statistical output from a horizontal temperature plot:

   Data Type = grid
   Dimensions = 0 1
   I Dimension = 1 to 73 Linear 0 5
   J Dimension = 1 to 46 Linear -90 4
   Sizes = 73 46 3358
   Undef value = -2.56e+33
   Undef count = 1763  Valid count = 1595
   Min, Max = 243.008 302.818
   Cmin, cmax, cint = 245 300 5
   Stats[sum,sumsqr,root(sumsqr),n]:     452778 1.29046e+08 11359.8 1595
   Stats[(sum,sumsqr,root(sumsqr))/n]:     283.874 80906.7 284.441
   Stats[(sum,sumsqr,root(sumsqr))/(n-1)]: 284.052 80957.4 284.53
   Stats[(sigma,var)(n)]:     17.9565 322.437
   Stats[(sigma,var)(n-1)]:   17.9622 322.64
   Contouring: 245 to 300 interval 5 
   

2. Here is an example showing how to overlay plots with the same axis range:

   * display a time series
   'set stat on'
   'd t(lon=180)'
   
   * get the yaxis range
   range = sublin(result,9)
   cmin = subwrd(range,5)
   cmax = subwrd(range,6)
   cint = subwrd(range,7)
   
   * draw an overlay
   'set vrange 'cmin' 'cmax
   'd t(lon=0)'
   'set stat off'
