LabPlot/CurveTracing

Datapicker is a tool that allows to easily extract data from image files. The process of extraction consists mainly out of the following steps:

• Import an image containing plots and curves where you want to read the data points from

• Select the plot type (cartesian, polar, etc.)

• Select tree reference points and provide values for them. With the help of these points, the logical coordinate system is determined

• Create a new datapicker curve and set the type of error bars.

• Switch to the mouse mode "Set Curve Points" and start selecting points on the imported image - the coordinates for the selected points are determined and added to the spreadsheet "Data".
