Generating a standard deviation plot from a row in a JTable

问题

I am trying to create a JTable that I can be able to click on a row and it will display a standard deviation curve. Here is what my JTable looks like right now.

So for example, the standard deviation for the string screen saver, action->login, login->disclaimer, ok would look like this (I plotted it in excel)

So my question is #1 is this possible and #2 if so then how?

回答1:

ChartFactory.createHistogram() with an IntervalXYDataset such as HistogramDataset might be a suitable choice. HistogramDemo1, seen among the statistical charts in the JWS demo, is an example. You can determine which row was clicked using a ListSelectionListener, as shown here. You can retrieve the required values from your TableModel using getValueAt(), as shown here.
