How can I change the Marker Style in a plotregression graph

Dear All I am doing a ANN modelling where a lot of regression graph is needed for presentation. I am planninf to present the regression graph with different marker. Normally matlab has 'circle' as a default marker type. Please guide me how to select different types of marker.

1. I tried this code but doesn't work. plot1 = plotregression(targets,outputs,'Marker','s','LineStyle','-',... 'DisplayName','Data',... 'Color',[0 0 0]); 2. The following code is applicable to select the default marker line, color but the default marker types cant be changed. y = xlsread('outputs.xls'); x = xlsread('DO.xls'); du = xlsread('Dates.xls'); figure %set(0,'DefaultMarker','*'); set(0,'DefaultLineMarker', '+') %set(0,'DefaultMarkerSize',7) set(0,'DefaultLineMarkerSize',6); set(0,'DefaultLineLineWidth', 2); %set(0,'DefaultLineMarkerColor','b'); plotregression(x, y,'All');

3. But in the normal graph I made a graph using different marker color, types and line width.

du = xlsread('Dates.xls'); plot(du,targets,'--*k','linewidth',2,'markersize',6,'markerfacecolor','k'); xlabel('Dates'), ylabel('Dissolved Oxygen (mg/l)') hold on; plot(du,outputs,'--xk','linewidth',2,'markersize',6,'markerfacecolor','w'); legend('Observed Value','Predicted Value')

I will really appriciate if you kindly guide me.Thanks in advance.
