Looking through the Hackaday archives, we’ve covered this subject a couple of times before. There is also a handy video tutorial which you can see below the break. If WebPlotDigitizer has engaged your interest, you’ll be pleased to know that it’s open-source, and you can find all its code on GitHub. A few rogue points to remove perhaps, but it does a pretty good job. Hit the “View data” button, and there you have it. Click the “Run” button, and your data points appear. Select “Automatic mode” on the right hand side, then click “Pen” and mark the graph trace, then select the colour of the trace. You also tell it if the axes are logarithmic at this point. It asks what type of graph you’ve loaded, in this case a 2D X-Y plot. It asks you to identify four known points on the axes and supply their values. So, open the WebPlotDigitizer app, load the graph image captured from the sheet as a JPEG. We’re going to try digitizing the current gain plot from the 2N3904 datasheet (PDF) that we examined a few days ago. So how does it work? Load an image with a graph in it, select some points on the X and Y axis, roughly trace the curve with a marker tool, and set it in motion. If you’ve ever needed it, you’ll know what we mean. But it’s still worth talking about, because it’s one of those tools to keep in reserve. WebPlotDigitizer is not new, it’s been around for quite a few years now. But you can digitize the graph to get yourself a lot closer to the action, and to help you in your quest there’s a handy online tool. You can’t knock on the office door of the engineer who created it back in the ’80s, he’s probably in retirement and playing golf or growing prize petunias by now. Wouldn’t it be nice if you had access to the numbers behind the graph! Meta-regression analysis showed that fMRI-guided targeting and short inter-trial intervals are associated with increased disruptive effects with rTMS.Have you ever had to write a bit of code to interpret a non-linear analog reading as picked up by an ADC? When all you have to work with for your transfer function is a graph in a semiconductor datasheet that was probably written thirty years ago and prints out the size of a postage stamp, that’s a rather annoying task. Stimulation applied at and 10 and 20 Hz slowed down RTs in attention and perception tasks. Meta-analytically, rTMS at 10 Hz and 20 Hz disrupted accuracy for attention, executive, language, memory, motor, and perception domains, while no effects were found with 1 Hz or 5 Hz. The final dataset included 126 studies published between 19, with 244 total effects for reaction times, and 202 for accuracy. ![]() To accomplish this goal, a quantitative meta-analysis was performed with random-effects models fitted to reaction time (RT) and accuracy data. Given the rapid proliferation of this approach, it is crucial to develop a better understanding of how online stimulation influences cognition, and the optimal parameters to achieve desired effects. However, online rTMS has also induced “paradoxical enhancement”. Online repetitive transcranial magnetic stimulation (rTMS), applied while subjects are performing a task, is widely used to disrupt brain regions underlying cognition.
