[quote=“tpochep”]>>1) in the RootBrowser App you says that "Using pan gesture along the selected axis,
you can change the axis range - “zoom”.".
I’m sorry, but I do not understand how to perform this task.
You first have to select an axis by a single tap gesture (an axis will be ‘highlighted’).
Ok, thanks, it works
- in the Tutorial App there is the possibility to rotate a Lego plot.
This possibility is absent in the RootBrowser App.
Have you planned to add also the rotation?
No, actually, in RootBrowser a pad view (edit mode) already handles too many similar gestures making
it hard to use - pan to zoom axis, pan to scroll, pinch gesture. So I decided to ignore this rotation feature.
- In RootBrowser it is possible to select and change
attributes but not to move the objects into a pad.
Have you planned to add this possibility?
I do not remember exactly, in principle, I remember I had a test version but at some
point I decided not to implement this - probably, with same reason as 2) but I’m
not sure why exactly.
- Have you planned to implement the “Fit” procedure?
Yes, and that’s quite easy to do I think.
Great!
- a canvas with more then one pad is supported?
No, since an iPad’s screen is quite small, I decided not to do this.
Ok, this should be a problem for me. I have a lot of root files where I have saved the canvases (TCanvas) of the AGILE satellite payload monitoring system. Each canvas has a set of pads.
It should be nice to display these canvases on iPad using your root browser (the files are accessible via http).
Could I convert the canvas into TPads (in fact, a TCanvas is a TPad)? Or do you think that implement the display of a TCanvas in the ipad root browser is feasible?
For the first option, this is the content of the file:
root [1] .ls
TFile** Canvas_1_n2.root
TFile* Canvas_1_n2.root
KEY: TCanvas Canvas_1_n2;1 0_3201 AC Ratemeters
Canvas_1_n2->Draw()
TPad* pad = Canvas_1_n2->cd()
pad->SaveAs(“test.root”)
but when I open the test.root I see a TCanvas.
I’m trying to
- store in a root file the TPad object already divided in many TPad(s)
OR
- convert each pad (with canvas->cd(M) ) and save each pad into a root file (maybe in different directories)
Let me know
Thanks for your help,
Andrea
