How can I avoid the point covered by line when plot?

*when I plot 5 lines and serveral square points in the same figure, the points are always covered by the lines whenever the command of points at the beginning (place1) or the end (places2).How can I make the points not covered by lines?

The code is:*

shadedErrorBar_legend3_h=shadedErrorBar(DateNumber_Ctp0,sm_Ctp0,std_Ctp0,{'-k','linewidth',1.5},0.2);
% Aq0_legend_h=plot(DateNumber_Ctp0(index_Aq0inCtp),sm_Aq(index_Aq0),'ks','MarkerSize',5,'MarkerFaceColor','r');    *%place 1*
gldas_h1_0000=plot(DateNumber_Ctp0,gldas_data1_0000,'-m','linewidth',1.2);
gldas_h2_0000=plot(DateNumber_Ctp0,gldas_data2_0000,'color','g','linewidth',1.2);
gldas_h3_0000=plot(DateNumber_Ctp0,gldas_data3_0000,'color',[.9 .9 .1],'linewidth',1.2);
gldas_h4_0000=plot(DateNumber_Ctp0,gldas_data4_0000,'color','b','linewidth',1.2);
Aq0_legend_h=plot(DateNumber_Ctp0(index_Aq0inCtp),sm_Aq(index_Aq0),'ks','MarkerSize',7,'MarkerFaceColor','r'); *%place 2*
