Area Auto Trace

Use the Area Auto Trace object (a rectangle object with grid lines in either X or Y directions) to auto trace line. The data points intersect with grid lines will be selected as the target point, the other data points in the same curve (or more accurate, the same part of the curve) will be auto traced and picked up.

To use this tool, click the  button, or the Digitize:Area Auto Trace menu items to enable, then in the original image, click and drag the cursor to select the area of the target points.

  1. Click the menu items Axes:Ternary Coordinate...,
  2. Ternary Coordinate Settings dialog pops up for you to define the axes orientation in the imported image, either counter-clockwise or clockwise. Click OK to apply the settings and close dialog
  3. When the Ternary coordinate system is chosen, and the Edit axis button ternary.png button is clicked, three reference points (P1, P2 and P3) are shown in the image. Drag the points to three vertexes of the ternary plot, and set the corresponding axes value
     
     

Polar Coordinate

To digitize a graph in polar coordinate system, you should define the coordinate first.

...

The new digitizer also provide a Magnifier to help customers to pick data precisely.
