Bar Graphs

[Osama Farroukh]

Hello,

I need a bar graph, Horizontal bar. Using Categories function, tax 0 is 1^st group, taxp5 2^nd and tax 1 is 3^rd. each group should have 2 bars, 1^st is 1A & 2A. 2^nd bar has 1B & 2B. Could someone please help how to do it?

It should be something like this. Two bars not four

I am grateful for any help!

Osama,

How about something like this:

graph bar tax0 tax5 tax1, over(condition)

Best,
Alan

Thank you Alan. It is not what I need. I would like to have 3 groups, horizontal, not vertical, and conditions (5A, 5B, 5C, 5D) should not be taken into consideration. I need just two conditions, the mean of 1A+2A and the mean of 1B + 2B

Please read and act on https://www.statalist.org/forums/help#stata We need

* a data example using dataex

* the graph syntax you tried

* the resulting graph so far

* above all, unambiguous specification of what you want

The example graph is hard, indeed for me impossible, to decode. No labels or titles! Is it supposed to be a graph of means -- which are central to the summarize results you show -- or a graph of counts or frequencies?

Dear Nick,

thanks a lot for your answer.

This is a data example using

dataex

I hope I do it in the correct way

I tried this syntax

graph hbar (mean) condition_1A condition_2A (mean) condition_1B condition_2B, over(ta > x0) over(taxp5)

and got the attached graph.

As I am a student and in the learning process, I am trying to replicate the graph done by a researcher (who provides me with the data). The provided graph is also attached. (In grey)

In the Original graph, we have on the y-axis three groups. One is the for people voted for no taxes (tax0), the second group is for people voted for 0.5$ tax (taxp5), and the last group people voted for 1$ tax (tax1). Also, we have 4 bars. But I need just two, which should be the mean of (condition1A + condition 2A) & the 2nd bar should be the mean of (condition1B + condition2B)

Thanks a lot for your help!

"Not sure if I post the graphs as described in the FAQ, If not please advice me"

This may help:

gen A = condition_1A +  condition_2A
gen B = condition_1B +  condition_2B  
graph hbar (mean) A B, over(tax0) over(taxp5)
