This interface shows at a glance which datasets are available from the most recent import operation. If a dataset is shown as empty, it cannot be plotted. Note that some data may be shown which does not really exist, due to wide variations in coding formats. You should consult this to check on any problems before reporting a problem about data not plotting. If no data is shown, check your source, the URL it came from (if any), and make sure the system clock settings are correct on your computer since some products are time-dependant.
