<br>
since having no one answering the original question.<br>

Is there a chance that i can get the matrix-values which are send to the (png-)workstation?<br>

Betreff: [ncl-talk] mean value of all displayed grid points / pixel in a map<br>
<div class="HOEnZb"><div class="h5"><br>
Hello,<br>
<br>
i have searched the function list but i have not found a solution for the following problem.<br>
<br>
I want to calculate the mean value of all displayed grid points in a map.<br>
<br>
This means:<br>
- i have gridded data for the entire world (gcm-results)<br>
- i plot a map (stereographic projection) for Europe<br>
<br>
NCL draws a rectangle map based on the given resource parameters. I am looking for a function which counts all displayed values (pixel?) and calculates an average value.<br>
<br>
Thanks in advance<br>
Frank<br>
