GetData Graph Digitizer - A Powerful Tool for Data Extraction from Graphs

How to Download and Use GetData Graph Digitizer for Free

Have you ever wanted to extract data from graphs, plots, maps or images? If you have, then you know how tedious and time-consuming it can be to manually measure and record the coordinates of each point. Fortunately, there is a software that can help you with this task: GetData Graph Digitizer.


GetData Graph Digitizer is a program that allows you to digitize graphs and plots easily and accurately. You can use it to obtain original (x,y) data from scanned scientific plots, maps, charts or images, when data values are not available. You can also use it to convert old graphs and charts into modern digital formats.

In this article, we will show you how to download and use GetData Graph Digitizer for free. We will also explain some of the features and benefits of this software, and how it can save you time and effort in your data analysis projects.

How to Download GetData Graph Digitizer for Free

One of the advantages of GetData Graph Digitizer is that it is free to try for 21 days. You can download it from the official website: The download file is very small, only 1.07 MB, and it works on any Windows version from Windows 98 onward.

To install the software, just run the downloaded file and follow the instructions on the screen. You will need to enter a registration key, which you can get by filling a simple form on the website. The registration key will allow you to use the software for 21 days without any limitations.

How to Use GetData Graph Digitizer

Using GetData Graph Digitizer is very easy and intuitive. The program has a simple interface that consists of a main window where you can load and view your graph image, a toolbar with buttons for various functions, and a status bar that shows information about your graph and digitization process.

The basic steps to digitize a graph are as follows:

  • Open a graph image file. You can use any of the supported formats: TIFF, JPEG, BMP or PCX. You can also scan an image directly from your scanner or copy an image from another program.

  • Set the scale or coordinate system of your graph. You can do this by selecting two points on each axis and entering their corresponding values. You can also set the scale automatically by using the AutoScale function.

  • Digitize your graph. You can do this manually by clicking on each point on the graph, or automatically by using one of the two algorithms available: Trace or Copy. The Trace algorithm follows the curve of the graph and detects the points automatically. The Copy algorithm copies the pixels of the graph image and converts them into data points.

  • Copy or export your data. You can copy your data to the clipboard or export them to a file. You can choose from several formats: TXT (text file), XLS (MS Excel), XML, DXF (AutoCAD) or EPS (PostScript).

You can also edit your data by deleting, adding or moving points, change the color or style of your graph, zoom in or out, undo or redo your actions, and more.

Why Use GetData Graph Digitizer

GetData Graph Digitizer is a powerful tool that can help you with many data analysis tasks. Here are some of the reasons why you should use it:

  • It saves you time and effort. You don't have to measure and record each point manually, which can be very tedious and error-prone. You can digitize your graphs quickly and accurately with just a few clicks.
