Expedition Navigation Software / Graph of Optimization Results

My guess is that the other data isn't there.

Hi Nick --

The table has many more variables. Here's a link to the image:

So, the question is why are the only variables being populated in the graph MSLP and TWS, while many more variables appear in the table?

Please advise,
Mark

I think we are going around in circles here. The meteograph only displays weather variables, except that TWA is in the bottom of the graphic. Your table only has 2 weather variables in it, so that's all that will display. If you had e.g. rain as a variable, or gusts, or SST, they would also be plotted, but the meteograph is exactly that ... a meteograph.

No wonder I was feeling dizzy. Thanks for clearing that up. Everything now makes sense :-).

Not so fast.... why does my meteograph not have TWA in it? Feeling dizzy again :-(.

Also, which verison of Exp.

You could also send the optimal2.dat file.

Currently running "v12.0.3x64 for Navionics". I am not able to find a file called 'optimal2.dat', and I did a global search looking for it.

If it helps here is a link to the grib file I was using.

Note: this file is over 100 MB. It is historical reanalysis data from the European Copernicus project. I was conducting a study of the passage from Oahu to San Francisco in the month of May. Looked at the years 2015 through 2024. Just doing this to get an idea of historically what the passage route would look like in May. Hope this helps?
Thanks for the help.
Cheers,
Mark

I should also note that I was using the motoring option... but, I just tried it with that turned off and I get the same problem, only TWS and MSLP graphed, no TWA (which would be nice to have for this exercise).

It is saved when you have the Load previous optimal routes option selected.
