Let us say we write an equivalent thing of Measure in Etoys. Then, kids can make their own graphing tool interactively. -- Yoshiki ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Using Matplotlib in Measure Activity
(my previous post didnt get posted it seems. If it did/does please ignore this copy) Hi, For some time I have been thinking about extending the functionality of Measure Activity into a tool that also allows for graphical analysis of data acquired not just from sensors/mic but data acquired from any source. For example this data can also be a set of values entered manually or something acquired say as RGB values from the camera. In this regard I am thinking upon two areas (1) A standard format for data sets. For example this could be data that the Distance Activity at a later stage logs as a set of distance readings or a set of sensor values (which Measure already reads)etc. At this point of time, I can think that data may represent information about more than one dimension also, for example pixel values in a picture taken from the mic. Is there an already (standard) set of existing data formats or ways of organizing and storing numbers that I can adopt or should I just make up my own ? (2) To allow for a variety of multiple views, representations and basically allowing more control over the way data is represented, I am considering using Matplotlib. See some screenshots here http://matplotlib.sourceforge.net/screenshots.html I still plan to explore this API a bit further, however does anyone have any immediate thoughts on this ? The main aspect being a comparison of the overheads of adding this package on the XO vs the long term benefits of having such functionality that other Activities can also make use of. thanks in advance.
