Selecting X-labels from Matrix
in [Matlab]

Prev: colour map from image
Next: suppose I have an equation x^2+x+y^2+3*y=5*y^2+3*y+3*x*y+5 andI want to find the set of (x,y) that satisfy the equation.
From: Kirsten on 12 Aug 2010 10:38 Hello all - I'm trying to limit the number of x-axis labels that appear. I am changing the labels from numbers to date text, but I only want 5 or 6 labels from the 5000+ string to appear at any given time. I can modify the script to allow only 5 or 6 to appear, but the wrong labels are used. I'm currently using set(gca,'XTick',0:1000:5000,'XTickLabel',x_des) If the original x-axis labels read 0, 1000, 2000, 3000, 4000, 5000, then when replaced will read 1/1/1900 0:00, 1/1/1900 0:01, 1/1/1900 0:02, etc. instead of the correct labels of 1/1/1900 0:00, 1/3/1900 0:30, etc. How can I tell MATLAB to look for the corresponding row in the x_des matrix? Thanks!

Hi You need to tell us the contents of the x_des matrix How big is it? Is it a cell array or a matrix? At a wild guess you want something like set(gca,'XTick',0:1000:5000,'XTickLabel',x_des(1:1000:5001,:)) but who knows? you do ... Ross |
