Where are you viewing the Pi3 dashboard - in a browser running on the PI?

If yes, check its console (_usually F12 key_) for errors

Also, tell us what type and version the browser is

Probably not related to your problem, but you will generally get a better layout if you use Grid layout on the page settings rather than Fixed.

For the future please see this post for the preferred method of posting flows here - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

I tried to download your flows, mostly to discover why you are using a different dashboard on a PC and on a Pi.

However, the flow would not import, so unless you fix that I don't think anyone will be able to help.

I mean I run node red via localhost by my Laptop. The chart was display good information. After that I run node red via Rasperry Pi and use node and configuration similar but the chart did not display information. I use slider node and chart node.

Where are you running the browser? Is that on the Pi too? You can run node-red on the pi but connect to it from the browser on your laptop.

Wherever you are running the browser you need to check the browser developer console as suggested earlier, and tell us which browser it is (Chrome, Firefox etc) and which version.

Perhaps you don't realise this @Bao:

The computer which Node-red is installed on does not need to be the same as the one running the browser with which you view the editor and dashboard.

So for example I have Node-red installed on a Raspberry Pi Zero on my home network.  
It's local IP address is 192.168.1.28 and I have set up the router so it always gets this address.

A Raspberry Pi is an ideal computer to _run_ Node-red on but gives a very unrewarding experience running a browser.

So I open a browser on my laptop and point it to 192.168.1.28:1880 for the editor and 192.168.1.28:1880/dashboard for the dashboard.

It would be helpful if you could describe what the fix was, in case anyone else has the same problem.
