Graphs

• RadiusCar graphs should support the landscape mode and resize appropriately by switching between landscape and portrait.

• One graph per screen mode should be supported.

• User should be able to filter input data for any graph by specifying the time period, car and odometer values range. Ex.: "for car No. XXX from 1.1.2005 to 31.10.2005" or "for car No. YYY between 20.000 km and 60.000 km".

• Following graphs should be available:
  • Consumption (ex. l/100km),
  • Endurance (km/l),
  • Unit (Fuel) cost (EUR/l),
  • Cost of fill (EUR),
  • Fuel cost per 100km (EUR/100km),
  • Distance per day (km),
  • Fuel cost per day (EUR).

• Each of the above-mentioned graph types should have it's own color (configurable).

• Each of the above-mentioned graph types should be switchable into monthly cumulative/average values.

• Last chosen graph type should be automatically saved - new opening of Graph window should show last used graph by default.

• Abscissa behavior for every graph should be configurable:
  • 1st option - the distance on the graph (in pixels) between fills is equal;
  • 2nd option - the distance on the graph is proportional to time between consequent fills.

• Ordinate maximal and minimal values should be configurable.

• In one-graph-per-screen mode following information should be printed along with the graph: minimal, maximal and average values of selected unit.

Diagrams

• RadiusCar should provide a diagram of cost split between different expense types.

Statistics

Statistics should be provided for selected Date or Distance range.

Statistics window should be subdivided into 3 sections and provide following information:

• General info section
  • Selected date range
  • Selected distance range

If Date range is selected by user, Distance range should be automatically calculated by RadiusCar. And vice versa.

• Total values section (for the range selected above)
  • Time period (days)
  • Distance (ex. km)
  • Fuel volume (ex. l)
  • Fuel expense (ex. EUR)
  • Overall expense (fuel + repairs + taxes etc., if supported)

• Average values section (for the range selected above)
  • Fuel only
    • Consumption (ex. l/100km)
    • Endurance (ex. km/l)
    • Monthly distance (km/month)
    • Fuel cost for 100km (ex. EUR/100km)
    • Monthly cost (ex. EUR/month)
  • Overall costs
    • Overall cost of distance (ex. EUR/100km)
    • Overall monthly cost (ex. EUR/100km)
