I want to create a chart based on an array.
The x-axis is the Timestamp and the y-axis the value. The line-chart wouldn´t show any data-points. Is the structure of the array correct to use it for an input of the line chart?

The chart node has good documentation built in on the side bar. It includes a link to more documentation that shows you the required format.

In particular you want the section Stored Data in [node-red-dashboard/Charts.md at master · node-red/node-red-dashboard · GitHub](https://github.com/node-red/node-red-dashboard/blob/master/Charts.md)
