About the tablestat Example

This example shows how to program callbacks for interactive data exploration,

including:

• An Opening Function to initialize a t a ble and a plo t.

• A uitable’s Cell Selection Callback to do plot selected data in real time as

the user selects data observations.

• A Pop-up menu’s callback to generate line graphs that display different

views of data.

• A context menu attached to an axes.

Use the GUI to plot different kinds of graphs into different axes for an entire

data set or selections of it, and to see how Fourier transforms can identify

periodicity in time series data. The GUI contains:

• A table of sunspot observations having two columns of data (dates and

observations).

• A second table, statistically summ arizing the data and a user-selected

subset of it.

• Two axes that plot time series o r Fourier analyses for the data and a

user-selected subset of it, each having a context menu that outputs its

contents to a new figure.

• A pop-up menu to change the type of data graph being displayed.

• A cell-selection callback that updates a column of statistics and a plot as

the user highlights observations.
