<div dir="ltr">Martin, <div>I agree with your assessment. </div><div>I assume the assumption of the designers (thank you Nyall Dawson et al for all of your amazing work) was that if you were displaying a continuous raster you would want a continuous legend as well. </div><div>As shown by your issue and in the links I shared with you the reality is that this doesn't fit all use cases. </div><div>I am considering writing up a feature request to address those issues.

<p>Sebastian, Bernd,</p>
<p>thanks a lot for your response. I checked the links Sebastian
sent. As far as I could see displaying data in the legend as a
continuum is a new feature in QGIS 3.18 which replaced the
previous method displaying data in the legend as categories (as
QGIS 3.16.4 is still doing - fortunately. Otherwise it would be
difficult producing maps in ongoing projects in a consistent
layout). And obviously there is no option available switching
between the old and the new display method. Personally I think it
was not a good decision giving up completely the categorical
display in the legend. In particular if you would work with
multiple colors and a large range of values, there is no way to
allocate map colors to the corresponding values, or vice versa.</p>
<p>So, I hope that the next QGIS version will include an option
which allows selecting the method how to display the data, as
continuum or categorized.</p>
<p><br>

<p>Regards<br>

<div>Which is exciting for me becasue that is how I would like
to have my continious data display. But it sounds like that is
not what you are interested in. I have not tried 3.18 myself
so don't know if there is a workaround. </div>
