Re: fill_bw_xy error

Hi Mary, Thank you, and it's very helpful to know that gsn_csm_xy3 is not overlayable. basically I want to: 1. plot three curves with different colors, and we call it plot1; 2. overlay each curve's 1sigma uncertainty with filling color A but no xylineColors to plot1, which generates the plot2; 3. overlay each curve's 2 sigma uncertainty with filling color B but no xylineColors to plot2, which generates the final plot, plot3. I tried to use the way you proposed by creating three matrices, each composed of five single vectors,  representing its mean value, 1sigma upper-lower bound, 2sigma upper-lower boud, and use  gsn_csm_xy3 to plot, but in this case, I could only use one filling color. Do you have any suggestions?  Thanks Jinqiang -------------------- Jinqiang Chen Environmental Science and Engineering California Institute of Technology 1200 E.

As far as I can tell from the modified script you sent me, you are using the same color for all the filled curves. Do you mean that you want a different fill color for the area above and below each curve, instead of one fill color for each region? Or do you mean for each set of three curves, you want a different fill color? Also, trying to overlay gsn_csm_xy3 on another gsn_csm_xy3 plot is not going to work, because gsn_csm_xy3 returns an object that already has overlaid plots on it, and you can't overlay plots that already have other plots overlaid on them. That's why you are getting the error: warning:TransformPreDraw: tfPolyDrawList element 0 is invalid When you see this kind of error, you should pay attention to it because it might mean you are losing some graphical information. If you can tell me what you are trying to accomplish by the "overlay" call (which in this case seems like you are overlay three line curves on two filled curves), then I might be able to suggest another way of doing it. --Mary On Aug 2, 2013, at 10:41 PM, Jinqiang Chen wrote: > Dear Mary, > > I tried your code and it works even though I got the same warning. However, if I want to use two different filling colors for two upper-lower boundaries (e.g., 1 sigma and 2 sigma interval), the code will become more complicated and I don't know how to code in your way. >  > Anyway, I changed your code in the way I did for my code.
