Definition and Meaning of Getdata Graph Digitizer
Getdata Graph Digitizer is a specialized software application designed for extracting numerical data from graphical representations, such as charts and graphs. It allows users to convert visual data into digital formats that can be utilized for further analysis, typically in spreadsheet applications like Excel. This tool is particularly useful when original datasets are unavailable, enabling researchers, engineers, and analysts to recover lost information from graphical sources.
The software operates primarily on Windows systems and supports various image formats, including TIFF, JPEG, BMP, and PCX. By digitizing the graphical data, users can obtain precise (x,y) coordinates that reflect the plotted points on the graph, facilitating quantitative analysis and reporting.
How to Use Getdata Graph Digitizer
Using Getdata Graph Digitizer involves several straightforward steps to ensure accurate data extraction. Here’s a breakdown of the process:
- Load Image: Begin by opening the desired graph image within the software. Supported formats include TIFF, JPEG, BMP, and PCX.
- Set Scale (Calibration): Define the coordinate system by selecting known points on the graph where the exact X and Y values are known, such as grid lines or axis markers.
- Digitize Data: Choose between manual and automatic digitizing methods. For manual digitizing, click on the graph’s curve to mark points. For automatic digitizing, utilize built-in algorithms to trace the graph's line or curve.
- Export Data: Once the data is digitized, you can copy the extracted (x,y) coordinates to the clipboard or export them directly into formats like TXT, XLS (Excel), XML, DXF, or EPS.
- Refine Data: Use additional tools to reorder, add, or delete points to enhance accuracy and ensure the data meets your specific needs.
