This menu point provides a graphic overview of the costs during the last 48 periods (months or years). It is based on the field "Purchase price". If the option "Include spare parts" is active, the costs of the spare parts are included. The date for the calculation is the date of the corresponding history entry.
You can select between annual and monthly reports. In addition, the selection can be limited to trains, makers, places or categories. After changing one of these fields, you must press the Button "Update" to recreate the list. Additionally to the standard functions, you can use the Button "Close" to close this window.
