Use the built-in "background eraser" if the graph has grid lines that interfere with the auto-trace tool.
In the world of scientific research, engineering, and data analysis, information is often trapped inside static images. Think of a valuable research paper from 1995—the graph is clear, but the raw data points are lost to history. Manually reading hundreds of points from a printed curve is tedious and prone to error. This is where graph digitization software becomes an indispensable tool. Portable GetData Graph Digitizer 2.24.rar
: Use automatic algorithms to trace simple curves or manual point-capture for complex or low-quality scans. Use the built-in "background eraser" if the graph
