Data Extractor 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 Data Extractor 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".
