Is this a bug in bar plot

Question

0 个投票

Something is not right with bar plot when some values are very very high and it is required to limit y values so that other values can be seen.

highValue=10E15;
y = [2 2 3*highValue; 2 5 6*highValue; 2 8 9*highValue; 2 11 12*highValue];
bar(y)

Now I want to limit yvalue so that I can see other values

ylim([0 10])

Now the results is:

No issue when highValue=10E14. Is this a bug in bar plot?

R2014b doesn't go outside the box boundaries but generates the same diagonal slash on the second group...

I suggest you to use two additional lines of code

highValue=10E15;
y = [2 2 3*highValue; 2 5 6*highValue; 2 8 9*highValue; 2 11 12*highValue];
bar(y)
set(gca,'YScale','log');
grid on;

I found this type of issue with plot function as well.

Is there really some mandatory reason to have such a large highvalue value, anyway, in reality?

Doesn't seem realistic use case, somehow...
