changing the shapes in the legend

[Denise Vella]

Hello I produced this graph from this code

qnorm nobaby, xline(1.2, lc(black) lw(medthick)) xline(0.74, lc(black) lw(medthick)) xline(0.59, lc(black) lp(dash) lw(medthick)) legend (order(1 " study Population" 2 "oLD Ratio") col(1) pos(5) on)

However I would like to change the green line to a solid black line.
I would like to change the dot to a dashed black line

The aim is to label the reference lines.

I don't want labels on the graph as it looks cluttered.

Creating a reproducible example here seems easy enough, right? Have you looked at

help qnorm

?

sysuse auto, clear
qnorm weight, rlopts(lc(black) lw(medthick)) ms(none) mc(black) connect(l) lp(dash) lc(black)

Dear Andrew, thank you for this.
So just to confirm, can I leave the plot as a scatter with line of best fit as it is (post 1)

But instead have a legend at 5 o'clock position - as it is, but instead within the legend i.e legend contents have:

---- = New ratio (which is the key to the broken reference line)
_______ = Old ratio (which is the key to the reference line)

Or is the only solution to label the reference lines ?

You can use the -addplot()- option to add the reference lines and they will be in the legend.

sysuse auto,clear

qnorm weight, rlopts(lc(black) lw(medthick)) ms(none) mc(black) connect(l)  lp(dash) lc(black)  /// 
    addplot(scatteri 5000 2000 1000 2000, recast(line) lc(green) /// 
    || scatteri 5000 4000 1000 4000, recast(line) lc(blue) )  /// 
     legend(order(3 "New Ratio" 4 "Old Ratio") pos(5) row(1))
