[IDV #TTT-288053]: Attempting to load point data into IDV

Hi Eddie,

I am not able to reproduce what you are describing. Would you mind making a move
of the animation and uploading it to:

old version of the IDV; you should upgrade to thelatest version (4.0u1). After 
June 1st, you will no longer be able to access dataon our data server unless 
you've upgraded, due to changes in the THREDDSand netCDF-Java software.> > >

am attempting to load the following data file into IDV. I suspect there may be 
a problem with date formats. The first column is combined date-time in MM/dd/yy 
HH:mm z format. The second and third columns are lattitude and longitude, 
respectively, of tornado begin points. I attempted to load the data simply as 
point data, not bothering with any sort of first guess. It returned the above 
error when I attempted to do so.> > Additionally, is there a way that I can 
change the appearance of the data? I would like to have the points represented 
by small red upside-down triangles, if possible, (since they are tornado 
locations.)> > ******************> Stack t race:>
