Getting started with the Graph Digitizer

Graph digitizer allows you to identify a 2D curve or 2D surface, and extract the numerical values of its data points. There are two main steps in extracting this data, which are reflected in the two tabs provided at the top of the tool dialog:

• Axis settings: here you define the X and Y axis scales.

• Curve identification: here you use the mouse cursor to select the data points to digitize.Note The Curve identification tab is only available when the axis settings stage is complete.
