QGIS automatically generates legends for single band rasters in the print composer legend window.

In the latest releases, it appears that the legend automatically creates a "Band" title in the legend as seen in the figure below.

Sample Legend

I find this unnecessary as the vast majority of the raster data that I deal with is single band and I dont wish to manually turn remove the band in the legend item everytime. My audience is not aware of raster bands and hence I dont wish to add this in the legend.

I am looking for the following output:

Is there a setting somewhere where I can turn off this behaviour for single band rasters? I could not locate it. Perhaps a default variable that can be editted?

  • I can't replicate this issue. What version of QGIS are you using and what raster data format? Commented Mar 19, 2021 at 9:19

Just stumbled on this problem myself... Found a (slightly hacky) solution.

Double click on the text that says "Band 1" in the Legend Items box of the layout. replace this text with a space i.e. " ".

Then, open the Spacing tab and reduce the "space between symbols" value to remove the gap created by the Band description.

Edit: I should add that I did this using the new continuous colour palette, I suspect it won't work quite as well using the discrete palette as in your example...

EDIT: following the comment from @itsgupta, they suggest a better solution which is to click on the offending 'Band 1' text and then hit the red minus button ('reomve selected items') to delete it.

  • Hugh, what QGIS version? What do you mean by "...the new continuous colour palette..."? Is there an old palette? Please edit your answer with screenshots. Commented Mar 26, 2021 at 16:31

    @hugh-graham Good solution. You can also click the "band 1" text in the legend and hit the red minus button to remove it. The problem is that there are lots of rasters in some atlas mapping and doing this process manually is tiresome. This is a new and unwelcome change in QGIS which I dont believe you can turn off by default. I am hoping there is a setting hidden somewhere or maybe it can be implemented/reverted in a future release. Commented Mar 27, 2021 at 1:29
  • @StuSmith There is a new continuous legend style for linear rasters. Previously they were discrete boxes in the legend. This issue is on QGIS 3.18 and higher. Commented Mar 27, 2021 at 1:31
  • Sorry for the delayed response. Thank you @itsgupta for directing me to the red minus sign solution - this is much better IMO and will work better with multiple layers etc. I'll add this to my awnser to increase its visibility. Commented Mar 30, 2021 at 10:04
  • @StuSmith I think itsgupta has answered these questions as well as I can. Happy to provide screen shots if this still isn't clear. If you go into layer properties for your raster > symbology > legend settings > check 'use continuous legend' box. This displays the colour palette as continuous in the legend of your layout.

To expand on what Hugh Graham and itsgupta have reported, I was initially unable to double-click on the 'Band 1' text; the icons below were also greyed out.

I solved my problem by unchecking the Auto-update button in the Layout's legend properties:

Before:

After:

Unchecking the Auto-update button allowed me to double-clck the 'Band 1' text, and it also exposed the red-colored minus button, allowing me to complete the steps described by Hugh and isgupta.

Other way is to just select the Band 1 Text and delete (click on the Minus sign) it. It will just remove the Band 1 text and not the Legend.
