The Data menu (the figure) contains buttons that manage aspects of the data bookmarks and downloaded data.
This button causes a list of the data bookmarks and the variable browser window to appear. You must select a dataset from the bookmarks window, as well as a variable, in order to submit a data request.
If you click on one of the variable names in the variable browser window, the Datasets menu window will only display the datasets that contain that variable. Similarly, if you have already made a selection of a dataset or a range, the Variables menu only displays the variables of datasets still on the dataset menu.
The Variables menu is persistent; after you have displayed it, it will remain on your screen until you close it. Sometimes the menu will seem to disappear; this is because your window manager software causes the browser window to cover over the new Variables menu.
Clicking this button invokes the bookmark editor. You can use this to edit items in the list of dataset bookmarks offered in the bookmark window, or you can add your own. See Section 2.2.7 for a description of the bookmark editor menus, and see Section 1.5 for an introduction to the operation of the editor.
If you want to add a bookmark, you should probably look at Chapter 3.
The OPeNDAP Matlab GUI supports having multiple files of bookmarks. Use this button to change the bookmark file currently in use.
If you want to replot data you've already downloaded, use this option, and you'll see the plot dialog you originally saw when you downloaded the data in the first place. See section 1.2.4 for more information about plotting.
Selecting this option causes all Matlab variables with names like R20_Pressure that have been created during the current browse session to be deleted. Effectively, this clears all variables created by remote data requests. Of course, if an Rxx variable has been copied to a variable of a different name, the new variable will not be deleted.
You can use this button to search for a text string. You can search the dataset names in the bookmark file, the variables made available by any of those datasets, the dataset descriptions, or the acknowledgements attached to each dataset. The searcher returns the first result it finds, displaying the associated dataset in the Text view. Click Find Next to see the next match.
The archive M-files that come with the OPeNDAP Matlab GUI are kept up-to-date in a central location on the DODS OPeNDAP Matlab GUI server, currently at URI. You can update your copies of these files at any time with this button. (See Section 1.4) Clicking this button pops up the Update menu, which gives you further instructions.
