Do you have a subscription with more barometers (eg. for different locations)? In that case you can use the powertool to make graphs that compare the different barometers (and the benchmarks). The powertool is also convenient if you have multiple copy-years in your barometer (eg. a copy with grey power for every year) and you want to display these in a graph.

The powertool is available for the CO2- as well as the environmental graph. You will find the powertool button in the upper right corner of the graph pages.

Powertool chart of one theme

Do you want to compare locations or years in the power tool on one theme, for example business traffic? Then select only that theme on the left and press the green refresh button. Just like the graph of one barometer, the graph is then split into the items contributing to that theme.
