Setting axes in bar function

Exemple

x=0:1:20

y=1;.9999999;.9999998;.9999997;.9999996;.9999996;.9999995;.9999994;.9999993;.9999992;.9999991;.9999991;.9999991;.9999991;.9999991;.9999991;.9999991;.9999991;.9999991;.9999990;.9999990]

bar(x,y)

-----------------------------------------------

The variation of my function is very small, and the values are very precise (1e-10)

I want to customize the way in which tick labels appear in Matlab plot axes

• 1/ modify the x and y axes limits (from min value to max value)
• 2/ display 10 decimal digits in y and x axes

This works:

figure(1)
bar(x,y)
axis([-0.5 20.5   min(y)-2E-8  max(y)])
xt = {get(gca, 'YTick')}
for k1 = 1:10
    xts{k1} = (num2str(xt{1}(k1),'%.10f'));
end
set(gca, 'YTick', cell2mat(xt), 'YTickLabel', xts, 'FontSize',7)

producing:

‘Star Strider: y0=1 not 0.999999’

Overlooked that.

Fixed now:

figure(1)
bar(x,y)
axis([-0.5 20.5   min(y)-5E-8  max(y)])
yt = {get(gca, 'YTick')}
for k1 = 1:size(yt{1},2)
    xts{k1} = (num2str(yt{1}(k1),'%.10f'));
end
set(gca, 'YTick', cell2mat(yt), 'YTickLabel', xts, 'FontSize',7)

use xlim, ylim options... you can simply give

 xlim=([xmin xmax]);
 ylim=([ymin ymax]);

or

 set(gca,'XLim',[xmin xmax]);
 set(gca,'XTick',[xmin:interval:xmax]);

 set(gca,'YLim',[ymin ymax]);
 set(gca,'YTick',[ymin:interval:ymax]);

for decimal places

 xn=get(gca,'xtick');
 set(gca,'xticklabel',sprintf('%.10f |',xn));

 yn=get(gca,'ytick');
 set(gca,'yticklabel',sprintf('%.10f |',yn));
