Dear list,
I am checking what Roassal can do and was wondering if I could use it for quick data analysis, e.g., to draw a simple xy-data graph from a file and play around interactively with that, with the possibility to zoom / zoom back, switch easily to logarithmic axes, etc.
So far I see RTGrapher, but as far as I can tell, no usable zooming functionality exists. Is there anything better?
Did you check the book? http://agilevisualisation.com
Yes, I especially checked
http://agilevisualization.com/AgileVisualization/Grapher/0203-Grapher.html
And the examples that are shipped with Roassal.
I went through them, too.
As far as zooming in/out is concerned, I only found that there are two tools:
Add RTZoomableBoxView
which allows one to zoom in a rectangle, but only as if the graph was a picture, i.e., no axes are redrawn, fonts get bigger, etc.
and
Add RTSelectionBox
which I haven't figured out what it is supposed to do (without reading the code).
I haven't found any more relevant example which would allow me to zoom in/back in the sense one needs to see more details from a graph.
Thanks Ruda
