How to Convert Hand Drawn Graphs to Vector graphics with Graph Converter Lite?
Start by opening the scanned document. BMP files only can be opened. You’re gonna have to convert it to JPEG, if JPEG is what your scanner is using. With the document scan opened, you should see something like this:
In this image you can see that we have opened a graph and we need to start the transformation from just this line to something that can be used by other software and application. Use your mouse and click on the begging of the graph in the bottom left corner. A small window asking for the value will pop-up. There enter the value which the created point should have in the graph.
Repeat the processes for two more points. When you’re done click on either Auto Conversion for the rest of the points to populate on its own, or you can click on the Manual conversion so that each one of the points can be converted manually. Do this with the red Add point tool at the top. As you are creating graph points, values in the right sidebar should change according to the three previously set marker values. When you’re done setting everything up, click on File >> Save or File >> Export depending on what you want to do.
