How to show the first bar?

Hi there,

I have a problem I don't understand how to solve:

clear all
a = [ 0    0.0985         0         0         0         0;
    0.0985    0.0245         0         0         0         0;
    0.1229    0.0024         0         0         0         0;
    0.1253    0.0062         0         0         0         0;
    0.1315    0.0207         0         0         0         0;
    0.1522    0.4889         0         0         0         0;
    0.6411    0.6418         0         0         0         0;
    1.2829    0.2781         0         0         0         0;
    1.5610         0    4.5649         0         0         0;
    6.1258         0    6.3255         0         0         0;
   12.4513         0    6.7345         0         0         0;
   19.1858         0         0    7.1922         0         0;
   26.3780         0         0    4.1167         0         0;
   30.4947         0         0   10.8742         0         0;
   41.3689         0         0         0    6.3609         0;
   47.7298         0         0         0    7.0327         0;
   54.7624         0         0         0    3.2231         0;
   57.9855         0         0         0         0   42.0145];

Put this in a bar chart:

graph1 = bar(a,'stacked','FaceColor','flat');
ax = gca; ax.YScale = 'log';

When I run this I get the graph which doesn't show the bar for the first column. If I zoom in on the graph I can find the bar

ax.YTick = [0.001 0.01 0.1 1 10 100]; 

and the labels

ax.YTickLabel = [{'10^{-3}'}
                {'10^{-2}'}
		{'10^{-1}'}
		{'10^{0}' }
		{'10^{1}' }
		{'10^{2}' }];

Still doesn't help. I would be ever so grateful for input on how I could solve this as the very first observation XTick #1 is just as important as all the rest

Set the lower limit on y-axis too. For example

graph1 = bar(a,'stacked','FaceColor','flat');
ax = gca; ax.YScale = 'log';

ax.YTick = [0.001 0.01 0.1 1 10 100];
ax.YLim(1) = 1e-2;

thanks a lot, I set the YLim to [0 102] and it didn't work, when doing as you suggested it worked. Thank you. Must admit I don't understand why, but I guess there is some sanity to it :-)

[Ameer Hamza]

I am glad to be of help!

YLim of 0 does not work on log axes. If you set something like [0.01 102] it would have worked.

[William Ambrose]

yes of course, what a retarded thing to do. I set the YLim first then log it, good catch and thanks for your help :-)
