Re: [ferret_users] a possible bug in the high resolution time series- depth section



Hi Golla,

Check and see if there are lots of missing values in your data.  The FILL command requires adjacent valid points in order to trace the boundaries of the color changes, so it is not suitable when there are lots of embedded missing values.

If you regrid using an @ave regridding transformation, then the coarser grid will have valid data as long as there is at least one valid point from the fine grid within the coarse grid cell.  So the number of missing values is greatly reduced.

Hi all,
 Now-a-days I am facing some problem with the high resolution time series data (5 second).
Suppose I am having data in z axis and t axis (5 sec) for suppose 5 days. When I try to plot the depth-time section using fill command, it is not plotting anything (blank plot) but scale bar will be there.The same data when I plotted with shade command, only second half of the data is plotted. Then, I checked whether data is there inside the .nc file or not. Suprising data is there inside. If I regrid this data to a coarser resolution in t-axis, again full data is plotting both either with shade and fill commands. I think this a bug or ferret is not able plot high resolution datasets. I didnt understand this weird behaviour. Any help in this regard is appreciated.

Thanks in advance.
