Hi Kwan, re: > Thank you for your reply. Yes, I referred to the surface wind barbs. OK. re: > But what I am trying to do is to change the proportional between the length of > the stem and the size of the head of the wind barbs. So changing the LSIZE > alone cannot let me lengthen the stem while keeping the size of the head > the same. That's correct. The LSIZE setting in the SFCPLOT.(CORE|SITE|USER) and RAOBPLOT.(CORE|SITE|USER) files, and the LSIZE= keyword for the corresponding McIDAS applications scale all parts of a plotted wind barb. re: > If this involve too much modifications of the code, then I will > just abandon this attempt. Since I have never looked for where one would do the kind of modification that (I now understand) you want, I can't say how easy/hard this would be. However, I can say that the problem in actually modifying "core" code in McIDAS would then require the same modification be applied each time a new release was installed. Since you are the only McIDAS-X user that has ever asked about this, it would not be something that I would consider to be important enough to adopt/implement in the Unidata McIDAS-X distribution, so you would be on your own. re: > Thanks again, No worries.
