[Qgis-user] Transfer color style from one raster to the other rasters.

[GILLEN Finbar]

Hi,

This topic relates to an issue I am having. 

Example: 

I have a project where I have joined a csv file to GIS file, I have created my set styling for the layer and saved the project

Every month I overwrite the existing csv file with figures for that month and this updates the csv file in the project. 

What I would like is for the gis file which I have joined the csv to, for it to recognize the new figures that are in the field I am using to symbolize the layer and classify it automatically without me having to hit classify. Hope that makes sense....Is this possible? 

Regards
Finbar

Hi Alexandre,
there is some problems on raster style
I tried to report it here https://issues.qgis.org/issues/20409
but it seemed like a local mistake,
actually even reclassify the raster with a rules file and trying to re-categorize it, the styling is not correct,  and the classification changes to paletted with tons of classes although I try to paste a style saved by a raster classified with same rules file

I think this is a big bug for those working with rasters and not a borderline bug as Giovanni Manghi wrote answering to me

Regards 

Antonio
