I would like to add a reference line to a boxplot, but I cannot do it. This is not much difficult, but I cannot do it in GAUSS as I do not work with GAUSS regularly.
A simple example code:
// some data for box plot x = rndn(100,1); // Box plot plotBox(0, x);
And I want to add a horizontal reference line of
y=0.5. Thank you in advance for providing help!
You can use
plotAddXY to add a line to any type of plot. The location of the first box will be 1. If you add any other boxes, the next boxes will be at locations 2, 3, etc.
So we will start the line at 0, which will be to the left of your box and continue it to 2 which will be past your box.
// some data for box plot x = rndn(100,1); // Box plot plotBox(0, x); // Line coordinates x_l = 0 | 2; y_l = 0.5 | 0.5; // Add horizontal line plotAddXY(x_l, y_l);
If you need to control the width of the X-axis to make this like you want you can use
