居然又攒出了一期特殊绘图小合集文章,本来以为要攒很久的,本系列主要拿出来一些简单的,单独拿来写篇幅会很短的绘图小技巧做个合集,本期代码为了绘制好看大部分情况使用了以下这段简单小代码进行修饰: function defualtAxes ax=gca;hold on;box on ax.XGrid='on'; ax.YGrid='on'; ax.XMinorTick='on'; ax.YMinorTick='on'; ax.LineWidth=.8; ax.GridLineStyle='-.'; ax.FontName='Cambria'; ax.FontSize=12; end 1 连贯填充堆叠柱状图比如写了如下代码绘制了堆叠柱状图: X=randi([0,5],[6,4]); barHdl=bar(X,'stacked','BarWidth',.4);把代码改成这样就能绘制带连贯填充的柱状图: X=randi([0,5],[6,4]); % X=randi([-2,5],[6,4]); barHdl=bar(X,'stacked','BarWidth',.4); % 以下是生成连接的部分 hold on;axis tight yEndPoints=reshape([barHdl.YEndPoints]',length(barHdl(1).YData),[])'; zeros(1,length(barHdl(1).YData)); yEndPoints=[zeros(1,length(barHdl(1).YData));yEndPoints]; barWidth=barHdl(1).BarWidth; for i=1:length(barHdl) for j=1:length(barHdl(1).YData)-1 y1=min(yEndPoints(i,j),yEndPoints(i+1,j)); y2=max(yEndPoints(i,j),yEndPoints(i+1,j)); if y1*y2=0,1,'last'),j); y1=min(ty,yEndPoints(i+1,j)); y2=max(ty,yEndPoints(i+1,j)); end y3=min(yEndPoints(i,j+1),yEndPoints(i+1,j+1)); y4=max(yEndPoints(i,j+1),yEndPoints(i+1,j+1)); if y3*y4=0,1,'last'),j+1); y3=min(ty,yEndPoints(i+1,j+1)); y4=max(ty,yEndPoints(i+1,j+1)); end fill([j+.5.*barWidth,j+1-.5.*barWidth,j+1-.5.*barWidth,j+.5.*barWidth],... [y1,y3,y4,y2],barHdl(i).FaceColor,'FaceAlpha',.4,'EdgeColor','none'); end end本来不需要写这么长代码,但为了应对有负数的情况才写了这么长,比如数据有负数会是这样: X=randi([-2,5],[6,4]); barHdl=bar(X,'stacked','BarWidth',.4);假设画了这样的图: X=0:.01:pi*5; Y=sin(X)+X./15; hold on plot(X,Y,'LineWidth',2) Uy=1.2;Ly=0;% Uy:上面的辅助线y值,Ly:下面的辅助线y值 yline(Uy,'LineWidth',1,'LineStyle','--') yline(Ly,'LineWidth',1,'LineStyle','--')填充颜色: fillColor=[114,146,184]./255;% 填充颜色 UY=Y;UY(UYLy)=Ly; fill(X,LY,fillColor,'EdgeColor','none','FaceAlpha',.9)同一坐标区域不同colormap,首先假如化了俩曲面: [X,Y,Z]=peaks(40); hold on;axis tight;grid on;view(3) surfHdl1=surf(X,Y,Z); surfHdl2=surf(X,Y,Z+10);设置配色: CM1=winter; CM2=pink; ZList1=linspace(min(min(surfHdl1.ZData)),max(max(surfHdl1.ZData)),size(CM1,1)); ZList2=linspace(min(min(surfHdl2.ZData)),max(max(surfHdl2.ZData)),size(CM2,1)); CMap1=cat(3,interp1(ZList1,CM1(:,1),surfHdl1.ZData),interp1(ZList1,CM1(:,2),surfHdl1.ZData),interp1(ZList1,CM1(:,3),surfHdl1.ZData)); CMap2=cat(3,interp1(ZList2,CM2(:,1),surfHdl2.ZData),interp1(ZList2,CM2(:,2),surfHdl2.ZData),interp1(ZList2,CM2(:,3),surfHdl2.ZData)); surfHdl1.CData=CMap1; surfHdl2.CData=CMap2;柱状图绘制误差棒很简单: Data=randi([20,35],[5,1]); err=rand([5,1]).*5; hold on barHdl=bar(Data,'BarWidth',.4); % 绘制误差棒 errorbar(barHdl.XEndPoints,barHdl.YEndPoints,err,... 'LineStyle','none','Color','k','LineWidth',.8)多组的就是加个循环: Data=randi([20,35],[5,2]); err=rand([5,2]).*5; hold on barHdl=bar(Data); % 绘制误差棒 for i=1:size(err,2) errorbar(barHdl(i).XEndPoints,Data(:,i),err(:,i),... 'LineStyle','none','Color','k','LineWidth',.8) end |
