Your suggestion showed up to be the best solution for me. My problem was that I had two different axes with the same rectangle. I had to draw two different rectangles in the two axes to make it work.

Re: [Scilab-users] Transparent rectangle?
Hi Antoine, yes it is planned to handle transparency... but it is not easy since it will probably break the compatibility (every function which directly use the colormap is expecting three color components... not four). As said previously, it is possible to workaround in using Matplot1 or Matplot which now (since 5.5 beta 1) is able to handle RGBA colors directly (without using the colormap).

Re: [Scilab-users] Transparent rectangle?
Hi Stefan, Yes it is possible: plot([1:2],[3:4;5:6;7:8;9:10]); Matplot1(uint32(65408), [1 3 2 10]) 65408=255*256+128, in hex notation 65408 is xFF80 (so it's a semi-transparent blue) When Matplot first argument is uint32, data are considered to be in format RGBA, there are more information at image_type entry: http://help.scilab.org/docs/5.5.0-beta-1/en_US/Matplot_properties.html Best regards Calixte On 19/01/2014 20:12, Stefan Du Rietz wrote: Hi all, is it possible to draw a filled coloured rectangle after lines so that those lines can still be seen trough it?

Hi Antoine, I understand that I could draw the lines after the coloured rectangle to get them visible, but I cannot do that. So, I need the rectangle to be transparent.

Hi Antoine, I understand that I could draw the lines after the coloured rectangle to get them visible, but I cannot do that. So, I need the rectangle to be transparent. What do you mean by "rearrange the order"? Pardon, but today you you print the line first. Later you print the rectangle (box). Since colors are solid, box color covers the line. If you somehow can find a way to rearrange your source-code so that you print the box first, then later print the line, then line will be visible. Alternatively if you print line, then print box, then print the line again - second line print will be visible through the box area. /Claus Stefan Antoine Regards Stefan ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users --- This email is free from viruses and malware because avast!
