Re: Stacked bar plot with positive and negative values

[Olivier Thomann]

Dear Tony,

Thank you for your answer. For what I know, usually stacked bar would look like this (same data in excel):

The negative value block would be in the negative side and the positive value on the positive side, without overlap.

Kind regards,

Olivier

Hello,

I am trying to plot a bar plot, stacked, containing positive and negative
value. Unfortunately, I don't manage to get a good result with the bar
function.

The stacked bar plot works well with positive values.

 z=[1 2 3
 4 3 1]
 h = bar (z, 'stacked');

And does not wok well with negative value. It seems the values are printed
on top of each other.

 figure
 z=[1 -2 3
 4 3 1]
 h = bar (z, 'stacked');

Do you know a way to work around this?

Kind regards,
Olivier

The output is what I would expect to see (bar of height 1, overlaid with a bar of height -2, overlaid with a bar of height 3) so you only see the last bar.  What are you expecting to see?
