Add horizontal line to graph

[Alexander Wuttke]

I use eclplot (ssc, Newson) to plot several coefficients.
I want to draw several horizontal lines. I am aware that this is possible with -xline()-.

However, these lines should not span the whole graph. These horizontal lines should start and end at specified points.
This means I am looking for a way to add a line to a plot, given four coordinates (x and y values for starting and end points).

This sounds like an easy question but I have not found anything on this.

I will be grateful for responses.

In the plot() option you can add twoway plot that are to be plotted on top of your eclplot. You can use a twoway pci plot to draw the kind of lines you want.

Perfect!
