应用水文模型相关的研究，一个重要的过程就是对模型进行校准和验证，最后将校准和验证结果表示在一张图上。这里将作图的matlab代码贴上供大家分享：

%%%%%%%%%%%%%%%%%%%%%code for hydrological model's calibration and validation

plot(yingluoxia, 'DisplayName', 'yingluoxia', 'YDataSource', 'yingluoxia'); figure(gcf)

ax1=gca;

box off;

ax2=axes('Position',get(ax1,'Position'),...

'XAxisLocation','top',...

'YAxisLocation','right',...

'Color','none',...

'XColor','k','YColor','k','XTickLabel',[]); box off;

hold on;

bar(yingluoxia(1:240,3),'DisplayName','yingluoxia(1:240,3)');figure(gcf)

set(gca,'ydir','reverse','xaxislocation','top')

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

注：这个代码能做出粗略图，具体还需要matlab的图片edit进行修改，以我自己的研究为例，结果如下：
