How exactly do I create a "Chart"?

Hello, so I’m trying to create a graph of an item

Number RasPIload { channel="systeminfo:computer:local:cpu#load" }

How do I do it and what do I exactly need?

Any help is appreciated. :slight_smile:

Did you see this: http://docs.openhab.org/configuration/sitemaps.html#element-type-chart

As a starter you would need to persist (in other words log) the data you get from this item. Without persiting the data, your graph would have nothing to show besides the actual value!
