Line graph only plotting at integer numbers

[Rinze Geuzinge]

Hello,

I have a question regarding the plotting of multiple lines in one graph.

The dependent variable is ROA, the independent variable is International Diversification and the moderating variable is Financial Openness.

I want to make a graph with international diversification on the x-axis, ROA on the y-axis, and three lines which represent different levels of financial openness. The range of financial openness is from 0.0025479 till 0.7704125, and I made three groups which equal ranges. The commands I use for this are the following:

quietly reg ROA IntDiv_lag c.IntDiv_lag#c.FinancialOpenness c.IntDiv_lag#c.IntDiv_lag##c.FinancialOpenness if FinancialOpenness >= 0.0025479 & FinancialOpenness <= 0.258502766 & ROA !=. & TobinsQ !=. & IntDiv_lag !=. & FinancialOpenness !=. & ln_Size_lag !=. & Leverage_lag !=. & RandD_lag !=. & Cash_lag !=. & PPE_lag !=. & CAPEX_lag !=. & ln_GDPpercapita !=. & FinancialDevelopment !=. , robust cluster (gvkey)

qui margins, at(IntDiv_lag=(-0.9932386/1.328827)) post

estimates store FirstThird

When I plot this graph it looks like the following:

At this point, Stata only plots points of the lines at the integer numbers of -1, 0 and 1. However, what I'm trying to achieve is to get the lines continuous, or when that is not possible, to get extra points at every decimal instead of just at every integer.

Hoping someone has some tips on how I can achieve this.

Kind regards,
Rinze

coefplot plots the coefficients, not the margins.
