[Tex/LaTex] pgfplot/tikz stacked bar chart, with compat=1.9 or later

bar chartnodes-near-coordspgfplots

Inspired by this question, pgfplot/tikz stacked bar chart, I've been trying to create a stacked bar chart with numbers at the end of the stacked bars. However, the location of nodes near coords was changed in pgfplot v1.9 to be over the centre of the bar segment. I've tried several things including setting nodes near coords style={text depth=2cm} but this obviously doesn't move with the data values. I've also tried making a 'topper' series, but this isn't the greatest solution IMO, and messes with reverse legend=true (though, this could be fixed with a more manually specified legend).

Would work pre 1.9:

Best Answer

The simplest solution would be to set the compat/bar nodes level back to 1.8. By doing that you can use all new features set by compat level except for the explicitly single set compat/... features.

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

[Tex/LaTex] pgfplots stacked bar chart with markers

I would really not recommend this plot because basically it's not readable and all data is dominated by Step 3 and predicted ones. First the question,

The plot goes up because you enlarge both limits, you need enlarge x limits=0.15,
I didn't get that error with your code.
You can do that via both declaring a width and a height dimension.

I cleaned up a bit, the code and the result is

As you can see, most of your data vanished and you have strange entries in your legend because those datasets are invisible.

Instead I can think of two options,

clean up the legend and mention only step3, step 5+6, and predicted columns with a disclaimer that the remaining step contribution is negligible and comparable
Combine your negligible entries into a sum and plot that but I can't judge whether it would be a good idea here for your application.
