I want a long graph that is likely to be zoomed in on, such as those in the zooming examples. However, at various points along the X axis I will want vertical lines with an annotation/label on each.
Firstly, how could this be done?
Secondly, when I zoom in, I presume the label is likely to disappear – since the y values of the line graph will be within a smaller range, it will automatically zoom in on the y axis as well, so cropping the label?
