Parsing data from a data bucket and visualize it on dahsboard

Hi, we are able to visualize data from the Bucket Explorer, into the a dashboard, but, is it possible to parse, or decode, or apply some small code to some specific fields before the visualization into the dashboard?

  • for example: my data includes a time stamp like that: 1498823889, and I need to generate a date time widget… is this possible?

  • another example: I have one field that is data: 0000090100, and the my voltage and temperature is encoded in some bytes of this frame… can I extract this values and visualize them into a widget?

I was not able to see this capability into the portal.
