HOW CAN I ADD MULTIPLE Y-AXIS?

Question

MY IMAGE HAS TWO Y-AXIS. CAN I CAPTURE THE DATA OF THE Y-AXIS IN ONE TABLE IN DIGITIZER?

Answer 1

To add and capture data from multiple Y-axes in "GetData Graph Digitizer," you'll need to use the software's feature for handling different scales or coordinate systems. Here’s a general approach:

1. Open your image in GetData Graph Digitizer.
2. Define the first Y-axis by specifying its scale and position using the software’s axis calibration tools.
3. Capture the data points for this axis as usual.
4. To handle the second Y-axis, you may need to redefine the Y-axis calibration to match the second axis's scale and position without changing the X-axis calibration. This might involve resetting the Y-axis settings in the software and capturing the points relevant to the second Y-axis.
5. Export the data points from each axis separately and consolidate them into one table manually outside the digitizer, using a spreadsheet application like Excel for further analysis.

Please check the software documentation or help resources, as some features might vary depending on the version you are using.

Answer 2

Use a charting library (such as Matplotlib or Chart.js) that supports dual or multiple axes, then configure each Y-axis with its own scale, position, and dataset.
