Aufgabenstellung

Zu verbessernde Grafik

Critics

Again, the main point of failure is the bad readability of the graph. The eye of the reader gets distracted by the load of information viewed in circles, which are more confusing than being informal. The vertical distance between the rows of data intensify this effect.
The graph should be consistent, so the 2x section confuses the viewer.
Because of all these critics, we decided to change the graph completly.

Redesigned Graph

Changes

Devided the graph into 3 smaller graphs with increased readability.
The first graph shows the average expenditures seperated by age group. The overall Expenditures are displayed by the red line, the total income before tax is displayed by the green line.
The second graph shows the absolut expenditures seperated by categories.
The third graph shows the same categories as the second graph, but instead of absolut expenditures, there are relative expenditures seperated within the categories by age group.
