Functionality
On this screen a Pie Chart
is shown, by selecting an item from the list on the right, an appropriate pie
slice is exploded from the pie. By clicking on the label marked EDIT in the
bottom right of the applet you are taken to the next screen.
On the left are two list components, the first is the selection for the label
to be used in the graph. The one below it is to choose the column for the data
for the graph, those options not selectable are disabled. Next at the top is
a RadioGroup selection for the type of graph you want, select from Pie Chart,
Bar Chart, Horizontal Bar Chart or nothing. Below this RadioGroup is a list
of all the elements in the chosen column (all the data labels). In the bottom
left are a button labelled next, which takes you on to the original screen of
the chart, or back which takes you back to the datagrid displaying the original
data.
The datagrid's functionality can be found on the datagrid page. But there are
also 3 buttons, Crop will delete everything in the table except that selected,
delete will remove those rows or columns selected, whilst reload will return
the datagrid to the original data from the data file.
