There is a line in the 'Help' tab:

> See **[this information](https://github.com/node-red/node-red-dashboard/blob/master/Charts.md)** for how to pre-format data to be passed in as a complete chart.

If you follow that link it will show you how to format msg.payload for a Pie chart and there are some examples you can lok at/test with.

I'm sorry , I don't know how to use that code. Where do I enter that code? Can I edit chart node or Add function and enter code.

Use CTRL+I to import a flow (don't put it in a function node - it's not JavaScript)
