So at the start of your script put something like:</span></div><div id="yui_3_16_0_1_1442088941204_5242" dir="ltr"><br></div><div id="yui_3_16_0_1_1442088941204_5241" dir="ltr"><b id="yui_3_16_0_1_1442088941204_6743">type = "png"<br><span id="yui_3_16_0_1_1442088941204_4326"></span></b></div><div id="yui_3_16_0_1_1442088941204_4574" dir="ltr"><b id="yui_3_16_0_1_1442088941204_6740"><span id="yui_3_16_0_1_1442088941204_4326">type@wkWidth = 2888 ; set these to whatever values you want<br></span></b></div><div id="yui_3_16_0_1_1442088941204_5240" dir="ltr"><b id="yui_3_16_0_1_1442088941204_6742"><span id="yui_3_16_0_1_1442088941204_4326">type@wkHeight = 2048 ;<br></span></b></div><div id="yui_3_16_0_1_1442088941204_5238" dir="ltr"><b id="yui_3_16_0_1_1442088941204_6741"><span id="yui_3_16_0_1_1442088941204_4326">wks = gsn_open_wks(type,out_file_name)</span></b></div><b> </b><br><div id="yui_3_16_0_1_1442088941204_3202" class="qtdSeparateBR"><div dir="ltr" id="yui_3_16_0_1_1442088941204_5394">Then at the very end of my script, I use the NCL "system" command to call ImageMagick to trim all of the white space at the edges of the plot.

I've tried a lot (e.g. gsnMaximize) but it doesn't work. The<br>height of the plot ist nearly perfect but the width is to small<br>(vpHeightF = 0.2, vpWidthF=0.6). When I change it in my .ncl file (e.g.<br>vpHeightF = 0.2, vpWidthF=1.5) I get the wrong result (see png1.2).<br>Therefore I ask you: How can I use all the space without any margin.<br><br>Beste regards,<br>Sebastian Giersch<br><br></div> </div> </div> </div></div></body></html>
