Hi all,
This may not be the place to post a question about data visualization, but many microcontroller sensor applications generate a lot of data. I need some guidance on how to display a set of data points. The independent variable is time of day in hhmmss.ss format. There are 3 dependent variables, which could be displayed within the same graph, or in separate charts, with the x-axis of each locked to the others. There can be about 100,000 data points over the course of 5 to 10 hours. I would like to be able to page through a chart of this data, being able to see details at the 1/2 second level; I would imagine 1 to 5 minutes per page would work. Since the dataset is not so large, I should be able to read all the data in at once.
I have used matplotlib before, usually finding a suitable example online, then modifying it to work with the data I want to visualize. I have seen online examples of using matplotlib with a scroll bar or forward-backward arrows, but they are nowhere near what I need to do. I am open to other python libraries, Obective-C or Swift as well.
Thanks,
Scott
