Create plot and pass some data

Hi ! I want to create a scatter plot but not to include all of the data. I use data from a spreadsheet and some of the values represent errors(for example 9999,-2112,1014 etc) and as a result I want to exlude them. Can I use any kind of filters to do that? I tried this : x(x==-1)=NaN; . The result doesn't seem right. I want to include the values of GHIGHIclear between 0 and 1,5(or 2).Please help!

Please provide any details, e.g. the used code as text (and not as screen shot) and the dimensions of the input. "doesn't seem right" is not useful also: Why not? What exactly does "between 0 and 1,5(or 2)" mean?

Perhaps:

match       = (0 <= GHIGHIclear && GHIGHIclear <= 2);
GHIGHIclear = GHIGHIclear(match);
