Re: [Scilab-users] color under a curve
Thank you Adrien and Christophe. The code provided by Christophe is specially simple and elegant, but assumes the function to be strictly positive. Filled areas are different when I change x to x = linspace(-2*%pi,2*%pi,100). For my purposes, it seems best to use xfpoly() for each region where the function has a constant sign. The drawback is that color choices are not as versatile as with plot(). JP Grivet ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
[Scilab-users] strange behavior of function xstring
Hello, I have noticed the following strange behavior of function xstring. This piece of code works fine: clear; clf(); s = A; plot2d(0,0,-1,010, ,[-2,-2,2,2]); xstring(0.5,0.5,s); This one does not (simplified exemple, no useful purpose): clear; clf(); function etiq(x,y) s = A; xstring(x,y,s}; endfunction plot2d(0,0,-1,010, ,[-2,-2,2,2]); etiq(0.5,0.5); Scilab stops with error message xstring(x,y,s}; !--error 2 Facteur invalide. at line 3 of function etiq called by : What do I do wrong?

Hello, De la part de grivet Envoyé : vendredi 15 mars 2013 10:58 For my purposes, it seems best to use xfpoly() for each region where the function has a constant sign. You can also perform several plot(), one for each region. The drawback is that color choices are not as versatile as with plot(). It is. All the colours of a colourmap are available.
