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','-'),...

};

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

xlabel('x轴','FontSize',15,'FontWeight','bold','Color','k');
ylabel('y轴','FontSize',15,'FontWeight','bold','Color','k');
saveas(1, 'result', 'jpg');

效果如下图所示：

};

x = 0:.1:10;

for i = 1:len
%    y = x.*log(x)+i*2;
y = x.*sin(x)+i*2;
hold on;

%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', 20, 'FontAngle','italic','FontWeight','bold',...
'Color',[1,1,1]);%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',[1 1 1],...
'FontSize',12,'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(0,'ScreenSize');
set(gcf,'Position',scrsz);

%%保存图像
set(1, '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(1,filename,'jpeg');
