Hello sir!

I want to set different marker and marker edgecolor on single line in Plot? Please, how can i do that, Thanks a lot!

Here example variable x, y. When under the value 12 (red line in photo), i want to set different marker and color for that two points.

x = 1:11;
y =  [30 27	31	28	9	34	33	35	33	33	10];
y1 = 12;
p = plot(x,y,'-k', 'Marker', '*', 'MarkerEdgeColor','g');
hold on;
plot(x,y1*ones(size(x)),'LineStyle','--');

plot is a single object for each line -- ergo, each line can have only one linestyle (colors, marker, line). To have a second marker/color/etc. means another line...

x = 1:11;
y =  [30 27	31	28	9	34	33	35	33	33	10];
y1 = 12;
hL=plot(x,y,'-k', 'Marker', '*', 'MarkerEdgeColor','g');
hold on;
yline(y1,'LineStyle','r--')
ix=(y<y1);                      % the offending locations
hL(2)=plot(x(ix),y(ix),'xr');   % put red 'X' there...
