how to adjust bar width (absolute value)?

Hello,

I am trying to plot using two different bar graphs in Matlab

figure(1)
bar(horizon1,data_2001(1:4,2),1,'b','FaceAlpha',0.6)

figure(2)
bar(horizon2,data_2002(1:5,2),1,'b','FaceAlpha',0.6)

I want to keep the width of each bar constant. However, I got something like below

The latter one has wider bar than the former one.

Is there any way I can keep the width consistent?

Thanks in advance.

I would point out that in one sense, your bars are the same width -- they both extend one unit (e.g. from 1.5 to 2.5). The reason their plotted width is different is that your x-axis extents are different.

So, one way to fix this would be to set the x-axis limits and xtick labels manually to be the same for both plots:

x1 = 1:5;
y1 = [100 800 1800 1700 200];
x2 = 1:4;
y2 = [200 1500 1400 400];

figure
bar(x1,y1,1,'b','FaceAlpha',0.6)
set(gca,'XLim',[0 6],'XTick',0:6)

figure
bar(x2,y2,1,'b','FaceAlpha',0.6)
set(gca,'XLim',[0 6],'XTick',0:6)
