On the Calculation page switch to the Cost Center Plan view.
Drag e.g. a cost center from the cost center plan on the left hand side to the calculation chart on the right hand side - repeat this step for additional cost centers.
A dialog asks to select the resource and how to add the series to the calculation chart.
Select the option Show itemized values to display each meter of the selected resource.
This means if a cost center has 2 meters assigned for electricity - select Show itemized values to see both meters and the sum of them in the chart (3 bars shown in the chart), otherwise the chart will only show the sum of the meters (1 bar in the chart).

Take care of the following difference! Adding a cost center with its meter to the calculation chart: the bar in the chart shows the consumption of the cost center. Adding the meter of a cost center to the calculation chart: the bar in the chart shows the total consumption of the meter. |

For good readability of the chart, the data is submitted to data binning depending on the length of the selected time period:
time period | bin size |
|---|---|
day | 1 hour |
week | 1 day |
month | 1 day |
year | 1 month |
Different kinds of data are shown at their respective time related to the bin:
data | time related to bin | value |
|---|---|---|
meter / meter reading | start-of-bin | Last known meter reading at the given point in time. |
meter / consumption | mid-of-bin | Consumption during the period of the given bin. |
trending | mid-of-bin | Value of the trending data after being processed by the configured aggregation function. |
