Vehicle speed and acceleration chart

The tools include:

• - enlarging the chart by 10%,

• - decreasing the chart by 10%,

• - enlarging given area,

• - activates moving of the chart,

• - automatically resets the chart dimensions into default ones in both axes,

• - automatically resets the chart dimensions into default ones in the horizontal axis,

• - automatically resets the chart dimensions into default ones in the vertical axis,

• - allows to save the chart to a file with the "bmp", "png" or "jpg" extension,

• - Statutory speed data - after expanding the field you can select additional sections - available only for Continental VDO tachographs, version 1.3 (since 2008), whose data were downloaded using special software (see the following topic: "Continental VDO since version 1.3 - Additional Sections" for a detailed description);

• - opens a chart print preview window,

• - moves the date back by one day,

• - the field of choosing a date of a day included in the range of read speeds,

• - moves the date forward by one day,

• - If you enter the precise time (date and time) in this field, the program will center the chart around the time and will broaden the chart to 10-minute span.
(5 minutes before and 5 minutes after the entered time)

For speed data downloaded from Continental VDO tachographs, version 1.3 and later, using special software (TachoReader Combo and TachoReader Basic  Speed data from VDO tachograph (S-file)) option) additional sections are available:

• - speed history of the last 168 hours of driving recorded with a frequency of one second;

• - last three records (high resolution - frequency: four values/second) of two-minute speed periods, in which there was an unnatural speed change in a short period of time;

• - last three records (high resolution - frequency: four values/second) of two-minute speed periods, in which there was a sudden, high change in speed ;

Availability of the above the section depends on the Special Data from VDO tachographs (S file) option selected during data downloading.

Options description:

•Speed graph [km/h] - displays/hides the speed chart;

•Acceleration graph x 0,1[m/s^2] - displays/hides the acceleration and deceleration graph;

•Show values on the graph - displays/hides the speed or acceleration values directly on the chart - the option recommended for use with high zoom;

•(Item 1 - Fig. above) - the upper speed limit - the chart will be displayed up to this value;

•(Item 2) - the lower speed limit - the chart will be displayed from this value;

•(Item 3) - dotted line - indicates the authorized speed.

Fig. bellow shows two enlarged charts. You can precisely define acceleration or speed for a given point in the chart. In order to do so, point out the required position with the mouse – the program will display a box with the information pertaining to the position.
