Combining and overlapping graphs using values within variables

[Adhikari Shubham]

Hi everyone,

I have four variables, Country, AgeCategory, EducationLevel, and Wages. I am trying to create a line graph of wages for Agecategory by educationlevel. I used following command:
twoway line Wages AgeCategory if Country=="Nepal", by(Educationlevel)

With this command I get two graphs for two values I have within education level. However, I want to have both lines for education level categories overlapped in the same graph so that I can repeat the command for other countries and combine the graphs. Wages and Agecategory are numeric variable while others are string. I had to make destring agecategory because linegraph was showing typemismatch error. Any help would be appreciated. Thanks.

Hi Adhikari,

Please try the following code and see if it achieves what you were hoping:

twoway line Wages AgeCategory if Country=="Nepal" & Educationlevel==1 || ///
line Wages AgeCountry if Country=="Nepal" & Educationlevel==2

Where '1' and '2' for Educationlevel are replaced by the actual values contained within that variable in your data. These could be strings, and so you would need to replace 1 and 2 with the labels in double quotes (e.g. "College")
