Hi HN, co-founder here! We designed Marple for engineers to make visual analysis intuitive and powerful. Most of our users are control systems engineers or test engineers (but not the kind that tests software). They often have to draw conclusions from millions of time series data points. As a quick example: logging data from a drone control system for 15 minutes at 1.5 kHz is already more than 1 million samples.<p>This creates some interesting technical challenges. We implemented a custom visualisation engine that efficiently displays only the data that fits the screen. In the same way, we also support applying functions such as low-pass filters, integrals, derivatives, etc.<p>Having a visual approach to analysing data is in our opinion still highly underrated. Common engineering tools such as Matlab or python+matplotlib scripts require you to reduce the number of samples yourself. And you end up with a plot that is not interactive: zooming, panning highlighting, adding a different signal are all cumbersome or impossible. Marple treats interactivity as a first class citizen.<p>We recently launched a beta version and we're currently looking for test users to try it out. If you sometimes need to visualise some data from a .csv file, python script, matlab script, simulation, ... you should give it a spin!<p>Cheers! Nero
How much does this actually cost? I don't see pricing anywhere on the site. I assume that info comes with the trial email but TBH I don't want to waste my time with the trial if it's going to be out of my price range.
Well that's just odd because I happen to live in Marple the town <a href="https://en.wikipedia.org/wiki/Marple,_Greater_Manchester" rel="nofollow">https://en.wikipedia.org/wiki/Marple,_Greater_Manchester</a>
Looks amazing! I’ve been using KST for years <a href="https://kst-plot.kde.org/" rel="nofollow">https://kst-plot.kde.org/</a> for interactive plotting but marple looks to have some features kst does not
Ooooooh interesting! Does it integrate with streaming or realtime services / db solutions? What's the max load you've tried out so far? Would you offer on-prem like Metabase?
Hello. Nice product, but some small problems:<p>- on MacBook 13", when editing calculated signals the dialog is bigger than the screen and the dialog cannot be closed (and maybe some other parts of the interface are hidden) - maybe add a max width/height on the dialog and a scroll<p>- the license does not work on windows (but works on mac build)<p>- on mac the feedback button the application splits in 2 identical views, with the mouse cursor movements mirrored (and an error about creating a folder .../bugs)
I guess I will take the opportunity to congratulate Marple and say (self promotion), that you have an open source alternative, that is equally able to deal with gigabytes of data and millions of points.<p><a href="https://github.com/facontidavide/PlotJuggler" rel="nofollow">https://github.com/facontidavide/PlotJuggler</a>
It looks likes this is a chromium/proton wrapper around a webapp.
Is that correct? The plot lib used seems very similar to plotly.<p>I'd be very curious to hear about some of the tech stack design choices.
I'd be also interested to understand who's your target user.
For some reason, your Website is broken on Safari: The images only show as a gray vertical line, about 5px high. Right-click -> "open image in new tab" works, so I'm guessing it's a CSS issue?
Nice! Having developped a tool similar in features at my current job, I'm about to start on my own a similar projects... Happy to see that this area get some traction.
