MultiSeriesGraph is the component for drawing multi-series graphs.
In our case, we use it for drawing temperature and cost graphs.
It can process one or more series.
Mainly, there are two important parameters: seriesNames and lineThickness, which help to adjust visual properties of the graph.

Also, the x axis in our case is time, although one unit in the series is considered to be minute, the numbers on axis are given by hours.
