Hi Roland & others,
 I want  to create time-series graphs using data from this file:

http://data.nodc.noaa.gov/thredds/dodsC/jason2/QA_assurance/jason2_igdr_pass_statistics.nc.html. All the variables I want to plot have two dimensions- time and stat_ind. stat_ind is the statistical index corresponding to mean, maximum, minimum, etc. So each variable has the data for all the indices. Now, I want to separate data corresponding to each index into a new (virtual) dataset within LAS. That is, have a different dataset for each index. Is it possible to configure this within LAS?

I tried using opendap urls such as this in the LAS configuration file:

http://data.nodc.noaa.gov/thredds/dodsC/jason2/QA_assurance/jason2_igdr_pass_statistics.nc?iono_corr_alt_ku[0:1:19880][3:1:3],<similarly other variables with general form- varName[0:1:19880][3:1:3]> which corresponds to Standard Deviation

But this doesn't seem to work. Though other OpenDAP clients like ncBrowse are able to read from these OpenDAP links properly and plot the indices in the desired way. Is there a way to configure LAS to do the same?

We might be able to come up with something. How are you configuring these into LAS for you tests? Can you post an example configuration here?

Thanks,

Roland
