Problems with positioning of data labels in a stacked bar chart created by Matlab App

I created a Matlab app to draw bar chart. The plot works fine. But, I am experiencing 2 problems:

1) It seems that I can not freely put the data labels where I want in the graph

2) I do not know how to te show/create the legend

Could anyone please advise me?

1. You can use xticklabels to add labels to the bar plot at points defined in xticks.

bar([2 3 4])
xticklabels({'first','second','third'})

2. Similarly the legend function can be used to add descriptive label for the plotted series.

legend('data')
