I have three line-plots on left y-axis and a bar plot on the right y-axis. how do I change line-style to 'o--' for every line on left y-axis. I am using following code, but it shows an error of 'Bad property value found'.

[Ax,hl1,hl2]=plotyy(time_step,surfaceflow1,prcp_datenum,prcp_excess,'line','bar');
set(hl1,'linestyle','--','linewidth',3)  % gives error if I use 'o--' instead of '--'
hold(Ax(1))
plot(Ax(1),time_step,surfaceflow28,'o--','color','r','linewidth',3)
plot(Ax(1),time_step,surfaceflow59,'o--','color',[0,0.5,0],'linewidth',3)
datetick(Ax(1),'x','mmmm dd')
datetick(Ax(2),'x','mmmm dd HH:MM')

I have attached the figure that I get with this code and other formattings. I am not able to figure out a way to change the line style of blue-curve to 'o--' as in other cases.

'o--' and others are shortcut inputs to plot commands when you don't pass a parameter. In this case, you are specifying a marker and a line style. When you pass the 'LineStyle' parameter, you can't include a marker identifier (the 'o'). Try:

set(hl1,'linestyle','--','marker','o','linewidth',3);
