Re: [Scilab-users] Filled polygons from polylines

Hi Samuel, Sorted out the code and it works.Had to manually set the filled areas upper time limit (t=97) (plot(-[97 t], [0 y1]) ). Set two graphic handles for upper and lower plot. Just random colours to test! Is there a way to do a loop over the curves to save multiple plots Thanks Lester

Re: [Scilab-users] Filled polygons from polylines

Hi Samuel, Thanks for the suggestion. I have not managed to get it working with the existing code as it generates an invalid index error; not sure what is going on. I tidied up the file for clarity. Following your example, plot(x, [0 y3 0]) would be plot(-t, [0 -xu(1,1:n) 0] ) in this code, but

Re: [Scilab-users] Filled polygons from polylines

Or better, to avoid artfefacts on boundaries: y = rand(1,20); y2 = rand(1,20)+1; y3 = rand(1,20)+2; x = [1 1:20 20]; clf, plot(x, [0 y3 0]) plot(x, [0 y2 0]) plot(x, [0 y 0]) gca().children.children.fill_mode= "on" gca().children.children.background= [color("grey30");

Think I spotted it... figure(1), clf f=gcf(); f.figure_size=[1024,800]; f.figure_name = "Subsidence of the Kufrah Basin Well A1-NC198"; f.background=8 // white background title ('Subsidence of the Kufrah Basin Well A1-NC198') // Figure title subplot (2,1,1) a=gca(); a.font_size=3

Re: [Scilab-users] Filled polygons from polylines

Hello Antoine, Your code does seem to work since the x locations are constant for each curve. However, I cannot see where exactly to apply the code for each layer within my existing code and how to apply different fill colours. This works to fill between the 2nd and 3rd polylines (see image):

Re: [Scilab-users] Filled polygons from polylines

Hello, The filled area is defined by 2 curves apparently; one is the top border and one is the lower border. Is it possible to construct a closed polygon using the points of both curves (something like C=[C1;C2] ) ? HTH Denis -Message d'origine- De : users De la part de arctica1963
