2Test application that uses plottools
3
4An application required by the REFL group and mainly test copy and print.
5   
6The following is a checklist of functionality to look for while testing:
71- Start the application:
8   the graph should have theory curve, experimental data, chisq
9   with a white background.
10
112- Hovering over any plotted data will highlight the whole data set
12   or line in yellow.
13
143- Left-clicking on the graph and dragging will drag the graph.
15
164- Using the mouse wheel will zoom in and out of the graph.
17
185- Right-clicking on the graph when no curve is highlighted will
19   pop up the context menu:
20   - 'copy image':    copy the bitmap of figure to system clipboard
21   - 'print Setup':   setup the size of figure for printing
22   - 'print preview': preview printer page
23   - 'print':         send figure to system printer.
