Hello,

I want to convert my transition matrix (see data/code below) into a "transition bar chart" as mentioned in these slides: https://www.stata.com/meeting/boston...14_nichols.pdf

That is, I want to plot the output of my tabulate command. There would be one bar each for the three values of lag_x (value of x in 2018) as shown in the screenshot attached which I made in excel. The composition of each bar would be according to the rows in the tabulate output: i.e. the values of x in 2019.I want to make many such figures and am looking for a way to do this in Stata.

Any help would be greatly appreciated!

Thanks.
