I am creating a plot showing how air pollution changes in a room over time. I have a record of activity in the room and want to colour the plot according to wether there is activity (1) or no activity (0), for which I have created a logistical variable.
I have used the below code but it is plotting no activity in yellow - which is very hard to see. How do I determine my own colours when plotting colour according to a variable?
scatter(Table.Date_Time, Table.PM_Concentration, 5, Table.Activity)

s = scatter(Table.Date_Time, Table.PM_Concentration, 5, Table.Activity);
s.MarkerEdgeColor = 'your color choice';
s.MarkerFaceColor = 'your color choice';
and so on..
