Hi! 

I tried making a bar graph with categorical data. However, the labels of the categories are not coming below the bars. Can you please help?

This is the code I used:

P = -2,920,000 -2,936,000 -2,935,000 -2,937,000 -2,939,000 -2,938,000

bar(P)

set(gca,"xticklabel",{'1JFF','α1aβII', 'α1aβIII', 'α1bβII', 'α1bβIII', 'α8β8'});

PFA a screenshot of the output.

Thank you and regards,

This is what you want:

P = [-2920000 -2936000 -2935000 -2937000 -2939000 -2938000];
bar(P)
set(gca,"xticklabel",{'1JFF','\alpha 1a\beta II','\alpha 1a\betaIII','\alpha 1b\beta II','\alpha 1b\beta III','\alpha 8\beta 8'});
 

Commas separate elements in arrays, or function arguments, or things like that. They should never be used to mark thousands, millions, etc. in code. If you check the axes on your graph, you'll notice that the tall bars are positive, whereas the numbers you entered are positive. You can also see a small negative bar for each -2. The spaces are from the 000 entries, and the tall bars are form the 9xx entries.
