matlab删除多余例,matlab中画如何去除分割线

xq的问题，想把Matlab的legend

点形状不想要多余的线，即将2-4的legendline去除。

解决：

line_fewer_markers是针对线的legendline off，对于点的legend off，我用的比较土的解决方法。即点位偏移一点点，形成线，再用作者的这个line_fewer_markers.m代码。

xx=-7:-6;

yy=polyval(P,xx);

plot(xx,yy,'-k','Linewidth',2)

hold on

line_fewer_markers([-6.488,-6.489],[-40.829 ,-40.828],9,'color','r','marker','^','MarkerFaceColor','r','spacing','curve','LegendLine','off');

hold on

line_fewer_markers([-6.455,-6.456],[-40.097 ,-40.096],9,'color','b','marker','s','MarkerFaceColor','b','spacing','curve','LegendLine','off');

hold on

line_fewer_markers([-6.376,-6.377],[-39.691 ,-39.690],9,'color','b','m极速赛车五码一期全天计划数据olor','b','marker','s','MarkerFaceColor','b','spacing','curve','LegendLine','off');

hold on

line_fewer_markers([-6.376,-6.377],[-39.691 ,-39.690],9,'color','b','marker','o','MarkerFaceColor','b','spacing','curve','LegendLine','off');

legend('降水线','120m处水','24m处水','干扰井水','Location','SouthEast')

最后结果
