Display static graphs like Sine

Hello,
is it possible to display a graph (like a sine) on the dashboard with static data?
The graph I would like to show will not change, I just want to show it.

Found the solution here:

# Node-RED-Dashboard Charts

## Live data

To display live data just wire up an input with a `msg.payload` that contains a number.


### Line charts

To display two or more lines on the same chart then each `msg` must also contain `topic`
property that identifies which data series it belongs to - for example:

    {topic:"temperature", payload:22}
    {topic:"humidity", payload:66}

Each series will be represented by a different colour.
Alternatively you can use the property `series` instead of `topic` if you prefer.

It is possible to create "gaps" in line charts by sending either a null or boolean false as the payload.
