Short answer NO.
When asking for a better way to display you are bound the get this suggestion.
I tried it, looks good, however I do stick to rrd4j because of it takes less ressources of my raspi.
Using Habpanel to show the graph you can use n3-line charts, preconfigured as the chart on classicUI, however looking great (to me).
For displaying single datapoints you can use the REST API., but that would be only a numeric display no chart.
