GUI to Interactively Explore Data in a Table (GUIDE)

discontiguous rows to a selection. Because the Cell Sele ction Callback is

triggered as long as the user holds the left mouse button down w ithin the

table, the selection statistics and lower plot are refreshed until selection is

completed.

Selection data is generated during mouseDown events (mouse drags in the

data table). The uitable passes this stream of cell indices (but not cell values)

via the

eventdata structure to the data_table_CellSelectionCallback

callback. The callback’s code reads the indices from the Indic es member

of the

eventdata.

When the callback runs (for each new value of

eventdata), it turns the event

data into a set of rows:

selection = eventdata.Indices(:,1) ;

selection = unique(selection);

The event data contains a sequence of [ row, column] indices for each

table cell currently selected, one cell per line. The preceding code trims the

list of indices to a list of selected rows, removing column indices. Then it

calls the

unique MATLAB function to eliminate any duplicate row entries,

which arise whenever the user selects both columns. F or example, suppose

eventdata.Indices contains:

This indicates that the user selected the first three rows in colum n one (Year)

and rows three and four in column two (Sunspots) by holding down the Ctrl

key when selecting numbers in the second column. The preceding code

transforms the indices into this vector:
