Select the symbol shape of the picked data points. Select the color of the picked data points. In the Symbols branch, you can customize the color, symbol and size of the picked data and also determine the result worksheet name:Įnter the name for the result worksheet which contains the coordinate values of picked up data points. You can set global options for the digitizer tool in the Options dialog. Go to the graph generated from the picked data points.ĭelete all digitized points, worksheets and graphs. Go to the result worksheet which contains the coordinate values of picked data points. Adjust axes as needed and click Pick New Points to start digitizing new data.ĭelete the current active line in the Data tab. This creates new output columns and also create a new line in the Data tab. This button is available only when picking points is done. Double-click on any digitized point to add a text label.

Rotate the image by defining rotation angles.Ĭlick to enter Axis Position mode when Cartesian coordinate system is chosen. Browse to select the image file you want to digitize. Open an image in Origin and import to the digitizer tool. 3.7 Pick Points for New Plot and Merge Picked Plots.Work can be saved into an Engauge DIG file. The process is import an image file, digitized within Engauge,Īnd exported as a table of numeric data to a text file. Engauge DigitizerĮngauge Digitizer, like DataThief, works on Linux, Mac and Windows. In this case, if the output distance is too small, the matched curved will go along the edge of the marker (big error if the marker is not too small). One defect of DataThief is the extraction of a line with marker. To extract a curve, one also need define the start indicator, end indicator and color indicator. Once you have defined the axes, scattered data or full curve can be obtained from Point mode or Trace mode.One can also use log axe with well choose axis option from Axis menu Fix the three location indicators (these have an X through there center) until the vertical quality indicator bar turns from red to fully green.Load the figure includes expected data.One will has to have the Java Virtual Machine. This means, that apart from the “excutable” called Datathief.jar, DataThiefĭataThief III is writen in Java. This program is developed using HTML5 which allows it to run within a web browser and requires no installation on to the user’s hard drive. WebPlotDigitizer was developed to be an easy to use, free of charge and opensource program that can work with a variety of plot types and images.
