Plotting a line graph of mean of variables with conditions

[Adriaan Arends]

Hi all I am pretty new to stata and Im wondering how I can display a two line grapgh of the same variable but with different conditions over time

So Ideally, I would have the values of mean on the y axis, and the years on the x axis and then two different color lines displaying the means

I have variables year, liquidity and treatment. So I would need to display the mean of liquidity over the years if treatment == 0 and he mean of liquidity over the years if treatment == 1

Could someone help me with this please?

Perhaps

egen mean = mean(liquidity), by(year treatment) 

line mean year if treatment == 1, sort || line mean year if treatment == 0, sort legend(order(1 "treatment" 2 "no treatment"))
