Drawing a bar graph with groups of X variables

[Aziz Essouaied]

Hello Stata Community;

I'm writing on this forum hoping I could get some help, because what I wanna do seemed a bit complicated, and perhaps not faisable aswell, but I'll try my best to explian my goal in the following.

I have this data:

It is basically 70 countries with their Economic Freedom score and their Gini index.
My goal is the following: Dividing the 70 countries into 2 groups:
-The first group is the more Economically Free countries according to the "Economic Freedom" variable
-The second group is the less Economically Free countries, again according to the "Economic Freedom" variable
The idea here is to get the 4 or 6 or 8 median countries of the whole 70 (it has to be a pair number so we could take an equal number of countries as medians from each sub-group) and to divide the 70 countries into less and more economically free, according to these 4 or 6 median countries.

Then, what I wanna draw is a bar graph with the Gini index for each country as the Y vertical axis, and for the X horizontal axis, I wanna have the bars of the sub-groups of countries (the less and the more economically free countries), so it's going to be a 2 graphs drawing into one graph, if you wanna say so. I don't need to show the names of the countries since they are going to be groped into two groups, but I wanna have the more economically free countries group (with their Gini index bars), and the same thing for the less economically free countries, both groups divided by these 4 or 6 median countries according to the economic freedom index.

As a start, I've tried these commands:
-graph bar (iqr) EconomicFreedom, over( Gini2017 , gap(10) sort(EconomicFreedom))
-graph bar (p10) EconomicFreedom, over( Gini2017 )
I guess this type of command is the right answer, but it just needs more options or something.

I hope I could get some help to draw the final graph that I wanna draw, either using the philosophy of those 2 commands, or other more sofisticated commands.

Thanks very much, community.

Needs a cross-reference to the previous version of this question: https://www.statalist.org/forums/for...iable-s-median

Ohhhh, sorry M.Nick Cox, I just totally forgot about that previous question. But, my idea is to use the "Economic Freedom" variable as a "division" variable, if you wanna describe it like so, my goal is not to have the countries's names individually, but more like divided into two groups: the less free countries than the 4 or 6 median countries according to that variable, and the more free countries than those same 4 or 6 median countries, and then for each country (of the 66 or 64 countries which are left (70-4 or 70-6)), within each group of the 2, I wanna represent its Gini index as a bar, all in a bar chart. And I guess that would be useful intra-group and inter-group comparaison.

I hope I explained my goal as clear as possible, Thanks very much.

The first post in this thread came 37 minutes after your last post in that thread, so you totally forgot about that earlier thread in between?

it’s fine to start a new thread when an existing thread seems to have stalled, but it’s good practice to give a cross-reference. That’s a standard point about Statalist.

On the more important point of the graph you now want, sorry, but I have stopped trying to follow. Each version of the question seems different and I don’t understand any. Nor it seems does anyone else, but I hope to be wrong on that.
