I've pushed a beta version of Dashboard to npm (not to flows catalogue). I have spent a wet Saturday looking at chart updates and trying to speed up reloads and data shifting. I suspect the main issue is actually buried deep in angular and chart.js somewhere - but I have found some hopefully useful gains... Hopefully none of the changes break anything but ... hence this request.
I would be grateful if a few of you could give it a whirl. In particular those of you with multiple charts.
This can be installed manually by going into your user directory and installing - eg
npm i email@example.com
Don't forget to flush local browser cache to ensure getting latest client side code etc... Feedback here please.
During test scope: add widgets to dashboard one by one, not connected to any node, do not configure anything but resolve the group , then deploy.

Thank you so much for your hard work. I have been dreaming of a fast chart from the Dashboard
I will give it a try though I have a busy schedule this week.
Don’t get your hopes up too high. I found a few duplicate calls and inefficient shifting. Nothing earth shattering. I can still kill the browser if I send multiple feeds several times a second.
Yeah. This is about charts
Just finished a quick testing. There are 12 real-time data curves in one chart. I used to limit the msg.topic rate to 5 per sec (send each topic in turn). If it is more than 5, then the chart can be unstable and cause losing connection error. Right now I increased the limit to 20 per second, the chart is running smoothly. I would say that it is much better than before
During beta installation, I did see a warning and error message. They are not affecting my flows so far. I trust that they will be gone during the formal release . But I will copy the messages here just in case:

I know. I haven't had any luck to break the charts yet
I do that test allways if I'm about to update some key components of my running home automation. And as this update seems promising, I started early.
All good here apart from a warning as mentioned above by davidz
npm WARN firstname.lastname@example.org requires a peer of node-red-dashboard@>2.15.0 but none is installed. You must install peer dependencies yourself.
Any more feedback ? If not I'll go ahead and merge it to master.
