I posted version 2.09 for download inhttp://www.tecepe.com.br/nav/vrtool/download.htm
* fixed problem in NOAA winds rounded to match VR winds ( thanks to Berg )
* fixed problem when importing your boat route (previous version imported some friend's route - thanks to Pascal )
* New Track Analysis
tool. Allows comparing the evolution in time of some variable of two boats (p.e. your boat and friend's). You can compare Distance to destination (DTD), Boat Speed, Rank, Wind Speed and VMC (for VMC calculation, current destination is considered). Results are shown as numeric table and line charts.
You can plot the variable difference
between boat 1 and boat 2. For example:boat1.VMC - boat2.VMC
If you are boat 1, a rising line is good for speeds (wind speed, boat speed, VMC), but bad for DTD (your opponent is gaining distance ).
Or you can plot the variable for both boats as different lines in the chart.
To open Track Analysis module select menu View > Track Analysis
(or shortcut Ctrl-Shift-A). Select the two boats, the variable, number of days and click [Calculate]
For the chart, I used the wonderful TeeChart
component. Click the chart button to configure. To zoom in
select a rectangle with the mouse. Use the zoom out
button to get back. Selecting a rectangle to the left also zooms out. Right-click and drag to move the chart.
Still some problem with friends data. Not all points are ok.
Variable values are extracted from boat tracks (TR_xxx), so you have to be collecting tracks to use this module.
