Hi there, I am using the PLOT package. When using the pd commands text, textc and textr, we have ... <quote> Argument is x y text, where x y are coordinates relative to the current window. </quote> with x, y element of [0 .. 1000] or pixels (using x suffix).
This is fine for some situations, but I would like to accurately place text using the problem space coordinates, in this case time (in years) for X and area (in square km) for Y. For example I need to place text at position [2009, 92000]. I can use a series of trials to position the text, but then with new data providing a changed scale for either X or Y axis (or both) such action is not a sustainable option. The commands Xticposn and Yticposn use problem space coordinates (the values to place ticks for the coordinate measured along the particular axis). I have trawled through the variables in locale jzplot looking for obvious transformations without success. Is there such a transformation available? I can see the usefulness in writing text using window co-ordinates, but there are other cases (eg labelling particular points on plotted lines) where problem space coordinates are necessary. Additionally the transformation of current text size would also be useful. This would easily enable calculation of (say) a text font character box size being, say, 1.24 years x 7256 sq kms.
