Scale tool

 

Before working with DTVD, it is sufficient at first to pre-select the paper size that is to be printed off later on. The need to provide scale information can be put on hold especially because the 'optimal' scale can change again when working on and adding further trajectories. After the distance-time diagram is complete, you can drop down the area in the diagram that is relevant for the valuation and display in a window with the scale tool or the mouse.

In the dialog that then appears, you can set the corresponding scales to 'round' scales or select suitable proposals from the menus. If the entire presentation of the currently selected  paper size appears to small, then you can change to a new format at any time.
