# How do I get the last group out, in this bar chart?

The last group that contains the year 2014 does not appear

• Hi, welcome. You're using ybar interval, you should be using ybar. See e.g. tex.stackexchange.com/q/355862 and tex.stackexchange.com/q/163590. Note also that it's always appreciated if you make complete minimal working examples, i.e. starting with \documentclass, containing the necessary packages/definitions (but not more), ending with \end{document}. In some cases an MWE is needed to figure out what's wrong, and otherwise it saves time for those who want to test your code to help. – Torbjørn T. Jan 7 '18 at 8:27

You made only one small mistake. Have a look at the comments in the code.
