Hi VisAD community,
I am using SpreadSheet as some of you will know, and am faced with a slight
problem. I have the following mapping:
(latitude,longitude)->(temperature)
I am trying to extend the spreadsheet class so that the user can select a
location to zoom into, for instance a map of Europe is shown and if user
selects South England it will zoom into that particular location. My
question is two fold, firstly what method actually sets the range. I have
checked GMCWidget and other widgets such as ContourWidget but not found what
I want. Maybe I have overlooked I am not sure.
Secondly I would like to know if there is a way to make sure what is outside
the range is invisible. I have imported the Europe map and have used the
widget that automatically pops up in SpreadSheet to changed the range for
Xaxis and Yaxis so that it seems to be zooming into a particular location.
However if I do this I get the a map which covers not just the range but
outside it too. I have read the VisAD tutorial in section 2.5 and it asks me
to select ScalarMap with SelectRange as DisplayRealType then it should solve
my problem. But I don?t know how to make use of this in SpreadSheet.
I would like to thank Curtis for his help from my last query.
Cheers,
Jacky
