Regarding stability - you are right.

I will make test with your design on my (old) pc and let you know.

Re: XY chart update speed

Dear Steve, Please don't nderstand me wrong. Flowcode is an excellent tool, but for measurements, xygraph (oscilloscope like..) is too slow. What I mean is that I don't understand, why it is not so fast as usualy graph software written in C is. Python which I use is described as a slow one in this c...

Re: XY chart update speed

Hi, Sorry, but I didn't see large improvement in speed. It takes too long to plot a simple graph like sinus. I also tested Fourier series graphing tests by Steve. If x is set to inc. by 1, it takes about a second to compute first 2000 points when calculating a single curve. Pyqtgraph in Python can d...

Re: XY chart update speed

Dear Steve, Thank you for your reply. I already tested the mode which collects points in buffer and updates all data at once, but I didn't find any improvement in speed so I sent the fastest version I made, for test. Regarding the new x-y chart, I would suggest you to add an oscilloscope-like chart ...

XY chart update speed

Hi, I found new Charts feature very interesting, only when I made a simple program to check the update speed I found it working very slow. If I deploy it as an app, it works even slower. On my computer it needs approx. 300 ms for one update of 500 points, for example in Python (which is slow), I can...
