Data can be either read in from an ASCII file (as pairs of x,y coordinates) or can be digitised directly into a data window using the mouse. Bitmap images to be digitised can be loaded into the data window from file. Fry plots are displayed in a separate FryPlot window within which a best-fit strain ellipse to the plot can be constructed using the mouse. Data and plot windows can be printed or copied to the clipboard, and digitised data can be saved to file. - see bugfix history for most recent changes.
