Graphs

Submitted by P Wright on Mon, 09/25/2017 - 10:13

Hi,

Thoroughly enjoying exploring PocketLab and its potential.

I have a few suggestions for the app, which I'm currently using on an Android tablet. If you do a long experiment, such as light or temperature over 24 hours, the line is quite thick when it is drawn. Could it be thinner to make reading the data easier? Possibly add the facility to zoom in on a particular range? Also, would it be possible to save the graph as well as the data? For a lot of the work in UK primary schools, the graph would be sufficient or a better output than raw data. If it was able to be exported as an image file it could be imported into other software for the pupils to annotate. I know they could screenshot it, but an export would be tidier.

Also, if the scale could alter itself to hours or even minutes it'd be useful. 86 400 seconds isn't as easily understood as 24 hours. 

Thanks,

Paul

Thanks so much for the feedback, Paul. These are great suggestions. Because PocketLab Voyager and Weather lend themselves to more long term experiments, we are already learning a lot from our users and looking for ways to make improvements. That's a good idea to make the graph thinner and easier to read and to convert he seconds to minutes or hours at a certain point. I'm not sure what's possible with our graphing library that is used in the software, but I'll look into it and get back to you. 

For zooming in on a particular range, do you mean a different function than the ability to pinch and zoom on a particular part of the graph? Maybe being able to do something like highlight a certain portion of the graph, and then having that highlighted portion fill the screen? If you've used our web app, instead of pinching and zooming, you use the mouse to highlight portions of the graph to zoom. I'm not sure how that would work on Android, but I'll check it out and let you know. (To use the web app go to thepocketlab.com/app in a Chrome browser on a compatible Android, Mac OSX computer, or Chromebook). 

In terms of being able to save the graph, we are working on cloud software where you could save your data and then view the graph in a way that's similar to review mode from your account on any device. There's a lot of development that goes into it, so it's still a little ways down the road. At some point though we will be looking for beta testers, so we can let you know. For now, a screenshot of the graph and then a download of the .csv file is probably the best. 

Thanks so much!
