![]() ![]() My first experiences are good: the software is easy to use, includes a nice magnification UI, and automatic curve detection works fine if the graph is “clean”.Īnd here's a list of other possible software from this answer on Cross Validated (link thanks to and Engauge Digitizer (free software, GPL license) auto point / line recognition. library(ggplot2) need stat 'identity' because we provide y values ggplot (warpbreaks, aes (x tension, y breaks)) + geombar (stat 'identity') + facetwrap (.wool) + ggtitle ('Breaks for wool A and B') This plot shows the total number of strand breaks. The later is something I had not thought about, but might actually be useful for some teaching needs (analysis of motion from a video). Frame-by-frame digitization of QuickTime movies.Automatic detection of curves (solid, dotted or dashed), symbols, bar charts, or perimeters of areas.Can plot confidence intervals for each bar, a lined grid behind the bars, change plot area color and logarithmic axes may be used. Creates a bar plot with vertical or horizontal bars. Of course, if given the choice, I'd prefer open source software running on Linux and Mac OS.Ī colleague suggested I use GraphClick, a Mac OS software that includes (according to its website): Enhanced Bar Plots barplot2 gplots Enhanced Bar Plots An enhancement of the standard barplot () function. I don't think it'd be appropriate to have extra requirements on the software, so I'm happy with free or commercial solutions, running on any OS. Is that even something that exists? What other tools can you recommend to work around this issue? Thus, I am looking for a data extraction software that could recognize individual points automagically, and possibly filter them by point color or symbol used. I currently use g3data to do that, but for large scatter plots having to click on every single point is tedious. Sometime, it's not even possible (I can hardly email the author of a 1936 paper!). Some authors never reply, or ask questions like “what do you want to do with it?”. If beside is true, use colMeans(mp) for the midpoints of each group of bars, see example. Most will do it, sometimes in nice ASCII format, sometimes in Excel files, sometimes in formats that I cannot open (chemists are fond of software like Origin or Igor Pro). same as fault, i.e., A numeric vector (or matrix, when beside TRUE), say mp, giving the coordinates of all the bar midpoints drawn, useful for adding to the graph. One option is to ask the contact author for raw data. For example, a scatter plot from which I would like to get a list of individual ( x, y) coordinates for the points. One axis of the plot shows the specific categories being compared, and the other axis represents a measured value. A bar plot shows comparisons among discrete categories. There are many times when I am faced with the task of extracting data from a published graph (usually a bitmap image in an paper). A bar plot is a plot that presents categorical data with rectangular bars with lengths proportional to the values that they represent. ![]()
