I'm currently doing a lot of experimentation with a product that involves logging bunches of data from test events, then trawling through it to find interesting bits.
Up until now I've been using gnuplot, octave and occasionally excel as the old favourites, but I find they're just too cumbersome for what I'm doing. What I need are things we'd typically expect on oscilloscopes and the like:
- Good zooming and panning that zooms the x & y scales properly in a readable fashion.
- Dropping markers with automatic calculation of difference in time or height between them,
- Getting point values by clicking on them,
- Fast working with large data sets (up to maybe a dozen million points.)
- Looks decent enough to show details to a customer without having to go re-render the portion of the graph in gnuplot.
Everything I've found so far is very concentrated on the scientific market that wants to produce publication quality plots. I've done that with gnuplot/octave and it works as that sort of tool. But what I want is a tool to quickly work through lots of data to make decisions on, like whether I need to re-do a test. Happy to spend a reasonable amount of money.
Thanks
