Fit not displayed

[Agustin Lobo]

Any reason why the linear fit is not displayed?

Not sure, please share the data for testing.

[Agustin Lobo]

Sure:

Perhaps this is related to the presence of nan, but note those are flagged as NULL in the GeoTIFF (NoData Value=nan):

Probably this is related to https://bitbucket.org/janzandr/rasterdataplotting/issues/14/handle-raster-with-nan-values-corectly

which is critical

[Andreas Janz]

Images with nan and inf values seams to work fine.

I guess you just need to check the All rodio button.

[Andreas Janz]

@Agustin Lobo , I just checked. In the 1.6.3 version is still a bug with nan values. I’ve fixed this already but the changes only become released with v1.7

[Agustin Lobo]

ok, looking forward to testing v1.7
