Thanks for adding the price in the x-axis!
Issue
However now there is a small inconsistency in the dashboard Expenses by Category graph and in a vehicle Expenses by Category graph.
In the dashboard, the currency abbreviation appears as the price unit below the graph, e.g., EUR.
However, in the same vehicle graph, the corresponding currency symbol now appears after each x-axis label.
In addition, when you hover over the “Expenses by Category” graph in the dashboard, the value is also displayed with the currency abbreviation. This is not the case, however, in the vehicle “Expenses by Category” graph.
Fix:
For consistency's reasons, a single graph style should be defined and applied throughout the entire application.
