Hi Wolfgang, Please check the code below using Matplot1() function. It was not easy to write proper code, as the help file is relatively poor for the Matplot1 function.
// START OF CODE // plot a matrix with Matplot1 clf() Nc= 128; // number of colors dxp=0:5:10; dyp=0:5:10; x1=min(dxp); y1=min(dyp); M= [64 30 2; 4 5 6; 7 8 33] // M can have any real numbers z1 = min(M); z2 = max(M); Mcol = 1+(Nc-1)*(M-z1)/(z2-z1); // scale data to colors indexes ax = gca();//get current axes handle ax.data_bounds = [min(dxp),min(dyp); max(dxp),max(dyp)]; //set the data_bounds Matplot1(Mcol,[min(dxp),min(dyp), max(dxp),max(dyp)]) drawaxis(x=dxp,y=y1,dir='d',tics='v') drawaxis(x=x1,y=dyp,dir='l',tics='v') f = gcf(); f.color_map = jetcolormap(Nc); colorbar(z1,z2,[1 Nc]); // END OF CODE Regards, Rafael -----Original Message----- From: users [mailto:users-boun...@lists.scilab.org] On Behalf Of SCHULZ Wolfgang Sent: Wednesday, November 23, 2016 4:05 PM To: Users mailing list for Scilab <users@lists.scilab.org> Subject: [Scilab-users] grayplot - colorbar Hello, I'm using Scilab 6 beta 2 under Win 10 and I have a problem with grayplot and a colorbar. With the following script I would expect to have at least 1 square colored in red because I scale the colorbar to the maximum of the matrix but with grayplot it doesn't work: map = jetcolormap(64); f=get("current_figure"); f.color_map = map; dxp=0:5:10; dyp=0:5:10; nb_xy=[64 30 2; 4 5 6; 7 8 33] colorbar(1,max(nb_xy),[1 64]); grayplot(dxp,dyp,nb_xy) Using Sgrayplot shows 1 corner in red but in this case I cannot see the individual grid cells what is absolutely necessary for me. What can I do? What is my mistake? Thanks for your help.
