Subfunction Summary for tableplot

The tableplot ex ample conta in s the callbacks l isted in th e following table,

which are discussed in the previous section. Click a function’s name to open it

in the Editor window.

Function Description

plot_callback

Called by the Plot check boxes to extract data from the

uitable and plot it, and to delete lines from the plot when

toggled

select_callback

Erases and then replots markers, showing only those that

correspond to user-selected cells in the uitable, if any.

The select_callback uses eventdata (cell selection indices); the other

callback has no event data.

Further Explorations with tableplot

You can generalize the tableplot GUI in several ways to enhance its utility:

• Allow the user to edit table values.

Enabling editing by the user involves setting the uitable

ColumnEditable

property to true and, if necessary, coding its Cell EditCallback.Editing

data cells might require updating the line plot and cell selection m arkers

if they are visible; to make this happen, however, you must provide code

to replot graphics similar to the code in the existing

plot_callback and

select_callback.

Note The refres hdata function updates graphs w hen workspace

variables that they display change. However, as the tableplot GUI contains

its own data sources, you cannot use

refreshdata within it for this purpose.
