Can PI Vision handle over 10K points on a display?
That's an interesting question. I'm impressed at your display resolution, for one thing! a 1080 x 1920 pixel display has about 2 million pixels, so you're only giving each of those 10k points about 200 pixels, or a 10 x 20 pixel range to be visualized, assuming you packed them in there as tight as possible. I'd love to see a screenshot or mock-up of what you're intending; I'm assuming you have a much larger monitor than I do--I suppose a 4K display, which has maybe 5x more pixels, could give you a better visual per data point (50 x 20 pixels, say).
I'm assuming, though, that you aren't asking about 10k individual data items, and more whether you could trend a time range that includes 10k points. The answer there, actually, is yes-thanks to a nice trick that PI Vision does.
I recently worked with a display that had hourly data for three AF attributes over 25 years, which translates to 25 years * 365 days/year * 24 hourly data events/day * 3 data items = 684375 individual data events. Here's a screenshot of that, below:
Now, you might be wondering--wait a sec, given what I said earlier, does my display really have half a million pixels in width? And the answer is no, fortunately! PI Vision actually takes into account the available pixels that exist on your display when it both draws the trend AND, more importantly, when it REQUESTS the data. Thus, it doesn't waste server resources pulling all .5 million events, since it knows that it can't actually display all of them--it instead calculates, server-side, what the trend would look like, and then it only retrieves the data points needed to draw that curve. Hope this helps! In short, if you're wondering whether you can trend really, really big time ranges in PI Vision, then our answer is yes, and if you're having trouble with this, of course, please reach out to us to that we can troubleshoot.
