You ride a bike or boat and want to know how much distance you covered in your last trip, but you do not have an odometer or GPS unit. You are a webmaster with visitor statistics charts and you want to do a statistical analysis. It is recommended to select at least 8 points for each. You are a graduate student gathering historical data from charts for your thesis. Now we select a curve and mark the points using the Segment Fill Tool or the Curve Point Tool. You are an engineer with some graphs in decades-old documents, but you really need the numbers represented in those graphs so you can do analyses that will determine if a space vehicle is safe to fly. The term "Engauge" in Engauge Digitizer was invented for this project, since there seems to be no similar term in common use. The final result is digitized data that can be used by other tools such as Microsoft Excel and Gnumeric.Įngauge (from en "make" and gauge "to measure") verb meaning to convert an image file containing a graph or map, into numbers. The process starts with an image file containing a graph or map. The numbers can be read on the screen, and written or copied to a spreadsheet. The image file can come from a scanner, digital camera or screenshot.

The Oculyze Plot Digitzer Online App can further be developed to work for a variety of charts, beyond the XY, so if you’re interested in a specific use case, contact us at Also, you can now test our plot digitizer online app for free.An open source, digitizing software that converts an image file showing a graph or map, into numbers
The imagePoints data are the same points but in pixel coordinates of the output image, thus not yet mapped to the axis scale. *The mapped Points are the x-y coordinates matched to the scale of both axis. Here is an example of how the digitization with the Oculyze Plot Recognizer works*: The data will be saved in a YAML file that you can then easily access and use. You can take any scanned image of a plot and almost instantly digitize the values of the plot. All that’s needed is the image of the plot and (for now) the X and Y values of the graph. The Oculyze Plot Digitizer Online App can digitize all that data in a matter of seconds, allowing the user to store a digital representation of the curve, along with the extracted values. A stress-strain curve can provide information about a material’s stiffness, strength, ductility and so much more.Ĭonsequently, there is an enormous amount of decades’ worth of data out there stored in graphs that are invaluable to engineers and other professionals in the steel industry.
A stress-strain curve, for instance, illustrates the relationship between stress and strain (stress being the measure of the force that a material is experiencing per cross-sectional area, while strain refers to the deformation of the material) and it is one of the most reliable tools for evaluating the mechanical properties of a material.

In the steel industry, but also in materials science and engineering, plots have been widely used in studies on material behavior. Engauge Digitizer (free software, GPL license) auto point / line recognition.

Step 6: Digitize the curve: Zoom in on the graph as necessary to get a. Let’s take the steel industry as a use case. curve images into this tool, and then digitizing the curve point by point. Oculyze has developed an App for digitizing plots, which does exactly that: it can extract data from a graph and map the exact values of that curve to the X-Y values.

They are widely used in academia, but also in numerous other domains having to do with technology, finance, or engineering, as they can easily convey understanding, more so than having mere lists of values.īut what happens when you have a series of plots that are of interest to your work and no way of accessing the data set behind them? You basically need to reverse engineer the images to extract the underlying data. Plots are visual representations of data sets illustrating the relationship between variables.
