Histogram or time-slotted plot graph

I have a water consumption meter, that produce a new value when another litre of water has passed through the device. Unfortunately default plot graph is not really handy for consumption analysis
consumption

Is there a graph component out of the box, or that could be easily installed that would:

  • show a histogram, or a plot graph
  • each value is a number of litres consumed during one full hour/day
    ?
