<div dir="ltr"><div><div><div>Hi Tabish,<br></div>By default panelling is done using the size of the first plot. Since your first plot has legend on top of the plot (I checked with dummy data) while others do not, and therefore the size of your first plot is larger than the rest. So in your case you can do several things, 2 methods:<br><br></div>1) Move the legend inside the first plot by playing with the resource "res@pmLegendOrthogonalPosF = -0.4", you may need several iterations to adjust. <br><br></div>OR<br><br><div>2) In panel resource list add this "resP@gsnPanelScalePlotIndex = 1" ; 1 means second plot since it counts from 0. This would force panel according to the size of second plot.<br><br><br></div><div>In general, I would also turn off or remove the res@gsnMaximize.<br><br></div><div>Other possible solutions include using viewport resources.<br></div><div>Cheers,<br></div><div>Rashed<br></div><div><br><br></div><div><div><br><br><br><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Apr 30, 2018 at 12:25 PM, Tabish Ansari <span dir="ltr"><<a href="mailto:tabishumaransari@gmail.com" target="_blank">tabishumaransari@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Hi Rashed<br><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Thanks very much for your email.
