[Scilab-users] color under a curve

[Dang, Christophe]

Hello,

If the curve is on one side of the x-axis
(i.e. always positive or negative),
then you can use something simpler,
but far less general.

// **********

// set of data for the example

x = linspace(-%pi/2,%pi/2,50);
y = cos(x);

// completion to have a closed area

xmin = min(x); xmax = max(x);
ymin = min(y); ymax = max(y);

x($+1) = x($); x($+1) = xmin;
y($+1) = 0; y($+1) = 0;

// filled area only

xfpoly(x,y);

h = gce();
h.line_mode = "off";
h.background = 4; // adjust to your colour

// curve alone (auto adjust of the axes)
plot(x(1:$-2), y(1:$-2));
