# Axis label is not displayed and adding labels to stacked bar chart

I have made this stacked bar chart but I can't get my x-axis label to be shown even though I have added them in the codes. Also, can anyone tell me how can I add labels to my stacked bar chart like in the picture ? Thanks!

• Thanks for providing a MWE. But, please edit your code so that it produces the erroneous result that you describe. As it is, it is not compilable. For instance you have \[ where it should just be a [ for optional parameters. – Peter Grill Nov 20 '18 at 20:51
• Thanks for the reply. I hope it's correct now. – thesilencer Nov 20 '18 at 21:49
• Did you try compiling it? – Peter Grill Nov 20 '18 at 22:21
• I'm not quite sure what's the mistake here because I extracted the table from my thesis and it's not exactly the whole thing. Did i miss any package that you can kindly enlighten me on? – thesilencer Nov 20 '18 at 23:26
• I get errors when I compile this.Please put this in a separate document and make sure it compiles. For instance, the Construction style is not defined, neither is the Construction color. – Peter Grill Nov 20 '18 at 23:34

It is somewhat hard to write an answer because this requires some fair amount of avoidable extra work. I ended up defining the missing colors somehow, and inventing a command \ac. Now to your questions:

1. You cannot see the xlabel since you put the legend on top. I moved the legend down.
2. You can add numbers with percentages using nodes near coords. I made a guess which numbers you might be after, and of course this guess is most likely wrong, but perhaps will allow you to modify things in such a way that you get what you want.
