Hi, everybody-- I'm having trouble getting plot_window coordinages and annotate_image_line coordinates to agree. I have a small region that I'm trying to annotate with lines, and zoom in on. I'm having trouble getting my coordinates working together. If I do proj = oober.pf.h.proj(ax,'Density',source=source) pw = proj.to_pw(center=proj_center,origin='domain' ) pw.zoom( 1/size) I have the object centered on the plot and zoomed appropriately. If I do proj = oober.pf.h.proj(ax,'Density',source=source) pw = proj.to_pw() pw.annotate_image_line(p1, p2, data_coords=True) the lines show up in the position I expect relative to my object. However, if I include both the re-centering in to_pw and the call to annotate_image_line, the line doesn't show up where I want relative to the object. If I skip the data_coords or origin argument it doesn't seem to help. I've dug around the docs and source but haven't sorted how to make the plot window coordinages and annotate_image_line coordinates agree. Thanks! d. -- -- Sent from a computer.
