symbology - Resizing symbols in QGIS Print Composer legend?


I am trying to map a count data type via graduated symbol against a chloropleth and the legend is too big.


The circles of the graduated symbols are the actual size of their corresponding values in the map, which is good for interpreting the legend but is not good because they overlap and in order for space to be created between them, the legend stretches absurdly along the y axis.


Is there any way to scale the circles back to half the size of the mapped symbols?


I stretched out the legend as you can see below, aesthetically it wasn't ideal.


this is what my map looked like when i stretched out the legend, it was rather ridiculous looking

Answer



I can see two workarounds:




  1. You can scale symbols on the layer to be acceptable size in the legend, add it in the print composer, uncheck "Update legend" and then scale the symbols back to previous values

  2. Add a second layer with scaled back symbols and then make the legend on the basis of the second layer while displaying the first one on the map
