Hello All!

I try to make graph using PDL::Graphics::Prima where there is a DataSet displayed by vertical line (these are positions of center of spectral lines). I use PlotType of ppair::Spikes. It is simple. But I want to write on the graph element names near each vertical line as I show in attached picture test.png generated by xmgrace program. How I can do it in PDL::Graphics::Prima? I try use Annotation Dataset ds:note and plot types pnote::Text. But in this case I should describe annotation for each line separately and when I zoom-in or zoom-out the graph or move it then generated annotations remain in places.
The file of data with annotation has format like:
6707.6 0.87 "CN1"
6707.8 0.92 "Li1"
.....
I understand that PDL do not read strings from data. But may by there is some method to display element names.



With respect, Yury
