How to design a correct twoway scatter graph?

[Lucas Bordure]

Good morning to the community.

I would like to design a graph like this:

But I would like firm_performance as yaxis and intangible_assets as xaxis.

I runned this command but I have an error code: "industry: may not use time-series operators on string variables" r(109).

scatter firm_performance intangible_assets, ylabel(minmax) xlabel(minmax), mlabel(industry), lfit fir
> m_performance intangible_assets, clstyle(p2)

Stata can't understand your syntax. If you get too far from correct syntax Stata just gets confused. This isn't enormously different from ordinary language.

Although there can be exceptions, the rule to follow is one and only one comma separating options from the rest of the command. Also you need different syntax for superimposing scatter and lfit.

 
 scatter firm_performance intangible_assets, ylabel(minmax) xlabel(minmax)  mlabel(industry) || lfit firm_performance intangible_assets, clstyle(p2)

Here the marker labels might as well be put where the marker symbols are.

 
 scatter firm_performance intangible_assets, ms(none) ylabel(minmax) xlabel(minmax)  mlabel(industry) mlabpos(0) || lfit firm_performance intangible_assets, clstyle(p2)

Thank you for your explanation concerning the syntax of options which is separated from the rest of the command.
Thank you also for your explanation concerning the syntax to establish to superpose scatter and lfit.
