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.
Reredesigned Graph
Changes
- Added captions to the axes
- Renamed some captions/headings
- Renamed the x2 section to 2x section
- Added the source of the information
- Decided not to delete the lines in the first graph to save the information provided by the original graph
- Graph 1 and 3 could not be merged, because the first graph shows the absolute expenditures, the third one shows relative expenditures. The two graphs can not be compared, because the first graph shows the total expenditures of the age group and the third one shows how much of their total expenditures they spend on what categorie.
