<p>... unless using an expression..</p>
<p>add a point layer with a column with value between 1 and 100</p>
<p>enable the data defined size controlled by the assistant</p>
<p>set the "value from/to" from 1 to 100, but the "size from/to" from 1 to 10 > size of points will be between 0 and 10</p>
<p>enable the "data defined size legend", size of symols will be between 1 and 100, resulting in huge (not usable) symbols in legend</p>
<p>Does only apply to the "separated legend items" option.</p> Bug report #19282 (Open): Data-defined legend is broken if "map units" are used https://issues.qgis.org/issues/192822018-06-27T11:45:49Zrobert kalasekrobert.kalasek@tuwien.ac.at
<p>symbol sizing with size assistant returns properly scaled symbols in the qgis/layer tree and the copmposer legend properties tool but doesn't show any symbols in the print composers' map legend at all. <br />a workaround which was done by unsing the layer styling / advanced / data-defined size legend returned valid results on any level if units are of "Milimeter", "Points" or "Pixels" <br />but if "Meters at Scale" or "Map Units" are used symbol size and symbol labelling in the legend are faulty and (!) do not match to sizes used within the map. <br />for exaples pls se the corresponding question in stackexchange <br />https://gis.stackexchange.com/questions/287514/qgis-composer-symbol-size/287547?noredirect=1#comment460764_287547</p>
<p>rk</p> Bug report #19099 (Open): Data defined Size legend is wrong when using separated symbolshttps://issues.qgis.org/issues/190992018-06-02T15:34:41ZHarrissou Santanna
<p>The data-defined size symbols feature has a set of unhandled issues i reported months ago (see <a href="/projects/qgis/issues?utf8=%E2%9C%93&set_filter=1&f%5B%5D=status_id&op%5Bstatus_id%5D=o&f%5B%5D=description&op%5Bdescription%5D=%7E&v%5Bdescription%5D%5B%5D=size+legend&f%5B%5D=&c%5B%5D=tracker&c%5B%5D=status&c%5B%5D=priority&c%5B%5D=subject&c%5B%5D=assigned_to&c%5B%5D=updated_on&group_by=">list</a>) but i think this one is a really broken feature that can lead to wrong information on maps.</p>
<p>Apply a scaled size to a point layer<br />At the bottom of the properties, choose to enable the data defined Size Legend<br />In the new dialog, choose "separated legend items", do the other settings and apply. <br />Most of the times, the symbols won't scale in the preview frame nor in the layers panel but the size displayed in the layers panel, hence in the layout legend, is really wrong. Really bigger than what's displayed in the map canvas. <br />If you switch to the "collapsed size symbols", you'll notice the difference of size and that sizes are coherent now.</p> Bug report #17464 (Feedback): Preview in Data-defined size legend dialog doesn't scale symbols si...https://issues.qgis.org/issues/174642017-11-14T15:55:27ZHarrissou Santanna

<p>Select the "Separated legend items" <br />In the preview section the symbols are displayed as a square symbol.</p>
<p>I think the user would expect to see them the way they would be displayed in the legend, with real proportions and vertically aligned.</p> Bug report #17462 (Feedback): Layer symbology in layer panel behaves weirdly when the legend entr...https://issues.qgis.org/issues/174622017-11-14T15:54:04ZHarrissou Santanna

(Feedback)">#17461</a>)</p>
<p>Reopend the "Data-defined size legend" dialog and update the title. Validate.<br />You should lose the separated proportional symbols in the Layers panel: often I get some square sized symbols that progressively (click by click) or automatically (after i click outside QGIS) become what is shown in legendpreview2</p>
<p>Note that collapsing then Expanding the layer shows a clean legend with full symbols.</p> Bug report #17461 (Feedback): Applying the vector layer properties dialog when diagram legend is ...https://issues.qgis.org/issues/174612017-11-14T15:52:24ZHarrissou Santanna
<p>Create a categorized symbology on a layer and expand its symbology in the layer tree (it might be optional but better highlights the effects imo)</p>
<p>In Vector Layer Properties dialog --> Diagrams, set a pie-chart diagram and add your fields<br />In the Size tab, set a variable size in order to enable in the Rendering tab, the "legend entries for diagram size" button<br />Click the button and open the Data-defined size legend dialog</p>
<p>Check the Separated legend items<br />Click OK and Apply in the layer properties dialog --> In the layer tree, you'll notice that the layer symbology has been collapsed, preventing you to see how the legend would look like in the layers panel (and legend in composer)<br />Note that this collapsing effect doesn't happen when you choose the "Collapsed legend" option in Data-defined size legend dialog (the collapsed/expanded state of the layer is respected).</p> Feature request #17066 (Open): Data Defined size legend: Being able to customize legend label and...https://issues.qgis.org/issues/170662017-08-24T16:24:25ZHarrissou Santanna

<p>Layer Properties > Diagram, set the options in order to enable the Legend entries for diagram size in the Legend tab<br />in the Data Defined size legend dialog that opens, it could be nice to by default populate the "Manual size classes" frame, with the values used to preview the legend (even though they are grayed).<br />This way if the user wants to customize, he can use some of the existing values. Also it'll make the frame more obvious (ie, you enable the checkox in order to modify these shown default values)</p> Feature request #16147 (Open): create symbol size legend also for centroid fillhttps://issues.qgis.org/issues/161472017-02-05T07:57:19Zmlennert -mlennert@foo.bar
<p>When displaying a point layer with proportionate size using the size wizard, the legend provides a nice symbol size legend.<br />However, when one displays a polygon layer using centroid fill, again using the size wizard, there is no symbol size legend. <br />It would be nice if the legend for centroid fill were the same as when using a point layer.</p>
