Making graphs of variables

[Thomas Kiekebosch]

Hello,

I want to make two graphs in Stata but I don't know how to do that.
I have the following dataset.

end

I want to make 1 graph with on the y-axis average patenting output (pat_yr variable) and on the x-axis variable maactive (dummy variable with 0 and 1 in it). So on the left side of the graph I want average patenting output when maactive = 0 and on the right side when maactive = 1.

The second graph I want to make is with on the y-axis average patenting output (pat_yr variable) and on the x-axis totalma (variable that counts the total number of M&A a firm has made, maximum value is 17). So I want to have graph that shows the average number of patents per number of M&A.

Is there anyone who could help me with this?

Thanks in advance
