OK.
Please find attached a sample that might help you.
Note:
It is possible to draw only an axis without showing the corresponding data.
Hence: One can create some "fake" or "foo" data not displaying them, but
showing the corresponding axis.
so using this principle, you can draw as many axes as you like..and place
them where you like.
clc();clear('all');
// all datashare same x axis// example: there are 1000 datapointsx1 =
linspace(1,1000,1000);
// each graph has it's own y-axisy1 = x1;y2 = 200*sin(1/20 * x1);y3
= sqrt(x1);
// create fake x-values for y-axisfake_x = zeros(1,length(x1));y1_min
= 0; // min-value for y1-axisy1_max = 100;
// max value for y1 axis
y2_min = -2; // min-value for y2-axisy2_max
= 2; // max value for y2 axis
y3_min = 10; // min-value for y3-axisy3_max
= 20; // max value for y3 axis
// create 2nd x-axis// example: the 1000 datapoints has been taken in
60 secondsx2_min = 0;x2_max = 60;dx2 = x2_max - x2_min + 1x2 =
linspace(x2_min,x2_max,dx2);
// create fake data for x2 axisfake_y = zeros(1,length(x2));
f = figure();f.background = 8;
drawlater()
plot2d(x1, y1,1);plot2d(x1, y2,2);plot2d(x1, y3,5);a =
gca()a.axes_visible(2)="off"; a.margins = [0.2 0.2 0.2 0.2];
// create y1 axisa1 = newaxes();plot2d(fake_x, y1);
// for fake_x = 0 creates a line on the y1-axis

In Kanada is' ka' na' da. Sonst wär' Kanada Jemanda.
There we have the salad.
