Matlab 曲线绘制之线型和颜色 示例

估计很多人会碰到，当绘制的曲线特别多的时候，需要用不同的颜色和线型区分开这些曲线。根据STC论文，自己整理了一个颜色和线型的例子，供大家直接使用，直接引用PlotStyle这个数据结构就可以了。

示例1

 PlotStyle={
     struct('Color',[1,0,0],'LineStyle','-'),...
     struct('Color',[0,1,0],'LineStyle','-'),...
     struct('Color',[0,0,1],'LineStyle','-'),...
     struct('Color',[0,0,0],'LineStyle','-'),...%    struct('Color',[1,1,0],'LineStyle','-'),...%yellow

     struct('Color',[0,1,1],'LineStyle','-'),...

   };

 x = 0.1:.1:10;
 len = length(PlotStyle)
 for i = 1:len
    y = x.*log(x)+i*2;
    hold on;
    plot(x,y,'Color',PlotStyle{1,i}.Color,'LineStyle',PlotStyle{1,i}.LineStyle,'lineWidth', 2);%call method
 end
 title('多种颜色和线性的示例','FontSize',20,'FontWeight','bold','Color','k');
 xlabel('x轴','FontSize',15,'FontWeight','bold','Color','k');
 ylabel('y轴','FontSize',15,'FontWeight','bold','Color','k');
 saveas(1, 'result', 'jpg');

ylabel('疾病预报y','Color','k','FontSize',,'FontWeight','bold','FontName','微软雅黑');%纵轴标题

%设置legend
hleg = legend('体检者1','体检者2','体检者3','Location','NorthWest');%本身不能设置字体的大小,需要通过set进行设置
set(hleg,'FontSize', , 'FontAngle','italic','FontWeight','bold',...
    'Color',[,,]);%Color为设置坐标的背景颜色

%%坐标轴刻度设置
set(gca, 'ytick',ya,'yticklabel',{' ',' ',' ',' ',' ',' ','','','',''},'xtick',x,...
    'xticklabel',{'','','','','','','','','',''}, 'color',[  ],...
    'FontSize',,'FontName','微软雅黑'); %xtick就是你要在哪些地方显示刻度，xticklabel就是显示什么内容

scrsz = get(,'ScreenSize');
set(gcf,'Position',scrsz);

%%保存图像
set(, 'InvertHardCopy', 'off');%设置的背景色有效,如果为on则图形不保存背景色，maltab 默认为 on
filename = 'test';
saveas(,filename,'jpeg');
