print(gcf, -dtiff, -r600, str);根据此案例可以发现当坐标轴1和坐标轴2刻度不一致时图1右侧刻度会与坐标轴2刻度同时出现那么此问题应该如何解决呢
2.3 案例3解决坐标轴1和2刻度不一致问题
成图如下 对比案例2修改代码如下
[ax,hlines] multiplotyyy({x1,droughtCharacter{1,1}(:,3)},{x1,droughtCharacter{1,1}(:,4)},{x1,droughtCharacter{1,1}(:,5)},ylabels);
set(gcf, Units, figureUnits, Position, [0 0 figureWidth figureHeight]);
set(hlines{3}(:),LineStyle,none,linewidth,1.5,color,mycolor(3,:),Marker,.,MarkerFaceColor,mycolor(3,:),Markersize,14);
set(hlines{1}(:),LineStyle,-,linewidth,1.5,color,mycolor(4,:));%,Marker,o,MarkerFaceColor,mycolor(4,:),Markersize,3);
set(hlines{2}(:),LineStyle,:,linewidth,1.5,color,mycolor(2,:));%,Marker,^,MarkerFaceColor,mycolor(2,:),Markersize,3);
set(ax(1),xlim,[0 nYear1],xtick,1:5:nYear1,xticklabel, yearStart:5:yearEnd ,FontSize,12,FontName,Times New Roman,XColor,mycolor(1,:));
set(ax(1),ylim,[0 33],YAxisLocation,left,ytick,0:6:33,yticklabel,0:6:33,FontSize,12,FontName,Times New Roman,YColor,mycolor(1,:),LineWidth,0.5,box, off);
ax1 axes(Position,get(ax(1),Position),...XAxisLocation,top,...YAxisLocation,left,...Color,none,...YColor,k);
set(ax1,XTick, [],YTick, []);
set(ax(2),ylim,[0 36],ytick,0:5:36,yticklabel,0:5:36,FontSize,12,FontName,Times New Roman,YColor,mycolor(2,:),LineWidth,1);
set(ax(3),ylim,[0 1.8],ytick,0:0.3:1.8,yticklabel,0:0.3:1.8,FontSize,12,FontName,Times New Roman,YColor,mycolor(3,:),LineWidth,1);
xlabel(ax(1),年份,FontName,宋体,FontSize,14);
ylabel(ax(1),ylabels{1},FontName,宋体,FontSize,14,Fontweight,bold);
ylabel(ax(2),ylabels{2},FontName,宋体,FontSize,14,Fontweight,bold);
ylabel(ax(3),ylabels{3},FontName,宋体,FontSize,14,Fontweight,bold); str strcat(pathFigure, Fig. 站点1安宁渡, .tiff);
print(gcf, -dtiff, -r600, str);2.4 案例4设置右侧俩坐标轴间距
根据案例3发现右侧两坐标轴间距过大通过修改原函数代码可调整其间距成图如下所示 具体修改multiplotyyy函数代码修改参数如下
% Set the axes position and size
pos [0.1 0.1 0.8 0.8];
offset pos(3)/10;
pos(3) pos(3) - offset/2;
ax(1).Position pos;
ax(2).Position pos;参考
