GeoArrays Plot example not producing the suggested output about geoarrays.jl HOT 9 CLOSED

Just note that we now support plotting rotated rasters as well. 🎉

from geoarrays.jl.

Well, GeoArrays doesn't rotate it. This is just a projected raster that has a lot of missing data around the edges, therefore appearing to be rotated. Sorry to disappoint.

However, your plot should be the same as the README. Could you post a screenshot, mention your OS and GeoArrays version? This might be due to your default Plots.jl backend. This is my result on Fedora (note the jagged pixelated edge of the raster, indicating it's non-rotated):

Apologies for having opened this issue. The code snipped produces now the desired output

I tried it several times before filing the issue, with restarting Julia in-between. Have no clue why it did not work then. Anyway, good so.

Regarding the "rotation": rotating may be not the most appropriate word. I meant that I am looking a way to plot a 2D field (data) as function of 2D x and y coordinate fields (as in pcolor() from PyPlot see here). As such, one could then pass x and y coordinate that are not aligned with the cartesian 2D axis. If you have any suggestions how to do this using Plots.jl I would be happy to know as It seems you do so to produce the example figure we are discussing now.

Does plot need to be exported or which plot backend are you using?
For the above example I get an error that that there is no method matching Plots with a GeoArray.

The plot backend should not matter, this package uses RecipesBase to tell Plots how it should be plotted. Could it be that you have an old version of GeoArrays installed?

Seems to be a Windows vs Linux issue. On my Linux environment (Julia 1.4) it has the latest version, however in Windows (Julia 1.4 and 1.5) it only updates to 0.1.0 - will check the dependencies etc. and see if I can sort out why

from geoarrays.jl.

Hmm the package compatibilities are platform agnostic. Probably a package in your environment is holding it back from the latest version. Installing in an empty environment should work. Or you can try pkg> add [email protected] to see what is the reason you are not getting the latest version.

Thanks, I was able to trace through a number of issues through GDAL, etc. the final culprit being a compatibility requirement of RecipesBase on JuliaDB.

FYI - regarding the issue flagged in the original post, I had initially experienced the same outcome but it was simply because the tif used in the Read TIF file example is different (lower quality and square as pointed out earlier) to the one used in the plot example. I suspect that should close the issue?

Happy to hear that you figured out the underlying issue! 👍
