Box Plots are a great way to understand data distribution. Replacing broken pins/legs on a DIP IC package. To label markers though, `standoff` is preferred over `xclick` and `yclick`.

If set to a x axis ID followed by "domain" (separated by a space), the position behaves like for "paper", but refers to the distance in fractions of the domain length from the left of the domain of that axis: e.g., "x2 domain" refers to the domain of the second x axis and a x position of 0.5 refers to the point between the left and the right of the domain of the second x axis. How to Read and Write With CSV Files in Python:.. Barplots are used to provide a straightforward comparison of data.

For relative positioning, "ayref" can be set to "pixel", in which case the "ay" value is specified in pixels relative to "y". How can I specify the sub plot in which to place the annotation?
