I am working on a data set which is looking at total number of fish landings in accordance with vessel length within the North Sea. After plotting the data I want to be able to categorize total number of fish landings in accordance to the length of the vessel.
I have attempted to use the Expression String Builder
within the Rule-based symbol
in properties
and symbology
, in which there are four categories available <=10
,>10-<=12
,>12-<15
, and >=15
. I want to be able to plot the length LENGTH_GP
of the vessel to total number of fish landings, with each category displaying a different colour.
Does anyone have any suggestions to this issue?
