Data may be read off the graph by clicking on the curve of interest. A slider is then displayed which may be dragged along the curve. The abscissa and ordinate are displayed in the bottom-left corner of the window.

The graphed data in any graph can be displayed in tabulated format by double clicking on the graph. This can be used to obtain the sectional area curve data for example. The complete set of data can be copied by right clicking on the top left grey cell to select the entire table, then selecting copy from the menu. If you wish the Copy operation to include the column headings, hold down the Shift key at the same time as you select the Copy command. The dialog may also be resized to best display the tabulated data.

You can specify whether a graph should be printed to a scale (to facilitate taking measurements from the graph). Holding down the Shift key while selecting Print from the File menu, or using the toolbar button will display the following dialog. Answering “Yes”, will mean that the graph is scaled so that one grid unit is a sensible number of centimetres or inches: either 1, 2, 2.5 or 5. The use of centimetres or inches will depend on whether the units used for length are metric or imperial. The setting will be remembered once the selection has been made; to change the setting, hold down the shift key again when selecting print to display the dialog. Choosing “No” will cause the graph to be printed filling the page and is the default behaviour.
