Hi !

In raster layers, we are able to either define the min/max either manually or from the data (with quite precise control allowing to ignore outstanding values).
The exact same feature should be available for graduated style for vector layers.

Then, one should also be able to choose whether he wants to clip features that are outside the defined range or to show include them in the lowest/highest class, again exactly like how you can do for raster layers.

For the sake of consistency, the UI should be the same between rasters and vectors (probably improving a bit the UI at the same time, since for now it's not very clear).

What do you think ?

Best,

Olivier

#31146 was a duplicate with some good comments.

just wanted to echo the desired functionality laid out in #31146. I currently achieve similar end result by building a query (often something like abs("VAR") < 5) but kinda clunky.

Very needed. It's possible to use an expression like min(max(0, "value"), 1), but this is not sufficient if the aim is to have a min/max bigger then the data (e.g. so that it matches another layer).

This would be so helpful to me. It would be great to get it on the development path. Thanks!

[talledodiego]

This would helpful to many I think.

Running into this as well. This feature would be very much appreciated.

Would be great to port these min/max features of raster Single Band Gray/Pseudocolor Symbology to vector layers Graduated Symbology as well (let min/max be user defined or computed or cumulative count cut 2%/98% percentiles etc).

This feature would be awesome indeed!

[andrewcharles]

Another bump for this feature. Thanks!

[NicBart]

This feature would be very much appreciated to filter out outliers which give a distortion to the visualisation of the dataset

[zawadzl]

This feature would help a lot, thanks!

Ok I did not know this. This is what i needed so hard, thank you.

Do you have a financial budget that could pay for this feature? I am sure a developer would be available.

Hi, I work for the french Space Agency, I will try to find some budget for this. It looks like I am not the only one needing this. I'll keep you posted. Any dev up for it?
