how does 'PI' differ from IoT ? at a quick glance "PI" seems to be a precursor to IoT, with all standardised components/450+ 'interfaces' etc

The OSISoft PI system has been around since the early/mid 80s. It was started by Pat Kennedy who had extensive experience in the oil/gas industry. The original name was "Oil Systems Incorporated". The system was designed to capture volumes of information from networked devices and stores the data in a proprietary format. The concept was always make data available to make informed decisions.
So, versus the IoT... OSISoft was around long before the IoT. As for '500+' interfaces, that is for the place where I work. We have 500+ interfaces, but that includes multiple instances of a particular type of interface such as: OPC, DNP, HabConnect, MODBUS, PI-to-PI (data transfer between systems) and, we have some custom written interfaces.

thanks for the info - shame you can't get younger people interested - if they cant program in node.js a lot of them dont seem interested - if I were in your neck of the woods I'd be asking what sort of experience I need to replace one of your retirees

So where are these charts you speak of?

Master's theses can occasionally be a gold mine. A long time ago I was working on a project where we had CMYK data that needed to be converted/interpolated into RGB space using a CMYK gamut sample set. The data wasn't ordered or well-behaved in any fashion. We found a thesis from a student at the Rochester Institute of Technology that performed the interpolation. The algorithm was a thing of beauty. It enabled us to even design a piece of hardware that could do the conversion in real time.

I wonder whether it would be better to make the chart's line fatter. Maybe with dithering around the edges to give even more sense of how noisy the original data is.

Sure, we'd love to have you hang around!

That was supposed to be a joke but I'm flattered that the founder himself has replied!
Thanks, I love being here too.

I think he got that.........hence 'hang' around.

I know, but I'm sure he's got a million other things more important to do.
Little gestures count a lot, I guess. I bet this would never happen on any other site.

You wait: there is a higher level which credit you as a "Master Debator".
You can make what jokes of that as you will...

I'll have to post a lot of offensive material then, to keep my reputation from ever reaching that level.
