It seems that you cannot have 'categorical' x axis for a line chart, only timestamp or linear, unlike the old dashboard with did support this. See also [Flowfuse Dashboard line chart using categorical x axis values](https://discourse.nodered.org/t/flowfuse-dashboard-line-chart-using-categorical-x-axis-values/98873), which I am hoping someone will produce an answer for.
