I have a point layer on a map displaying delays at bus stops. When i customise the range for the colours, the colour legend updates to the limits specified. To add a further layer to the data i would like to show the size of the buble to be proportional to the delay as well. When i customise the range in the "Size & Shape" properties, the legend of the bubles do not change, but the size of the bubles on the map appear to update.
How to get the size legend to agree with the numbers.
The prefered scale is between -5 min and +5 min (300/86400)
The legend shows between -30 min and +17 min
