axis()species to which axis theyline(), xline(), or tline()is to be applied. Suboptions axis()is for use only when multipley, x, ortaxes are being used (seeG-3axis choice options).

*A second, minor question is that I do not understand why the x-axis gets an elipsis (.) when I add the scatteri plot. Options yline(linearg), xline(linearg), and tline(time linearg)specify the y, x, and t(time) valueswhere lines should be added to the plot. I have tried adding axis(2) to the text box as an additional argument, but this option is apparently not allowed. It seems better to be able to attach the text to the line using the second y-axis gridpoints. Of course, I could manually determine this value for the histogram (as I did in this example), but I plan to create a set of these graphs via a loop, such that there are a dozen or so panels. The corresponding lines would instead be: text(1 `median' `'median = $`=string(`median','%6.2f')''', /// Instead of '0.08' which gets my text into the correct location, I would like to use '1', as this is the maximum value of the second y-axis.

This is the reason I used the second y-axis in the first place. This produces the desired graph (for the most part*):Īt issue is that I do not know the height of the histogram beforehand. Scatteri 0 `median' 1 `median', recast(line) yaxis(2) /// Twoway hist mpg, start(10) width(5) || /// Here is an example of my issue: sysuse auto However, I cannot seem to add text to this line using the second y-axis coordinates (it instead uses the first y-axis coordinates, even though the object it is labeling is on the second y-axis). To fix this, I am using scatteri with coordinates.īecause I do not know the height of the histogram beforehand, I set the scatteri plot to use a separate y-axis, which I have hidden. I cannot use xline() because the line falls behind the histogram, rather than on top of it. coefplot offers various options to label coefficients, equations, and subgraphs, include labels for groups of estimates, or to insert subheadings to structure. I have a plot of a histogram, to which I would like to add the median.
