matlab如何使得subplot(2,2,1) m_contourf(lon_real,lat_real,spring_mean') colormap(m_colmap('jet','step',100)); m_gshhs('fc','patch',[0.8 0.8 0.8]); m_grid('box','fancy','fontsize',12); h=colorbar('eastoutside'); title('春季','fontsize',12); title(h,'°C','color','k'); subplot(2,2,2) m_contourf(lon_real,lat_real,summer_mean') colormap(m_colmap('jet','step',100)); m_gshhs('fc','patch',[0.8 0.8 0.8]); m_grid('box','fancy','fontsize',12); h=colorbar('eastoutside'); title('夏季','fontsize',12); title(h,'°C','color','k'); subplot(2,2,3) m_contourf(lon_real,lat_real,autumn_mean') colormap(m_colmap('jet','step',100)); m_gshhs('fc','patch',[0.8 0.8 0.8]); m_grid('box','fancy','fontsize',12); h=colorbar('eastoutside'); title('秋季','fontsize',12); title(h,'°C','color','k'); subplot(2,2,4) m_contourf(lon_real,lat_real,winter_mean') colormap(m_colmap('jet','step',100)); m_gshhs('fc','patch',[0.8 0.8 0.8]); m_grid('box','fancy','fontsize',12); h=colorbar('eastoutside'); title('冬季','fontsize',12); title(h,'°C','color','k'); 四图的间隙变小

可以尝试使用subplot间距设置函数`subtightplot`，代码如下：

% 设置subplot间距为[左侧、底部、右侧、顶部]，单位为norm
gap = [0.05, 0.05];
margins = [0.1, 0.1];
subplot = @(m,n,p) subtightplot (m, n, p, gap, margins);

% 画图
figure;
subplot(2,2,1);
m_contourf(lon_real,lat_real,spring_mean') 
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('春季','fontsize',12); 
title(h,'°C','color','k');

subplot(2,2,2);
m_contourf(lon_real,lat_real,summer_mean') 
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('夏季','fontsize',12); 
title(h,'°C','color','k');

subplot(2,2,3);
m_contourf(lon_real,lat_real,autumn_mean') 
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('秋季','fontsize',12); 
title(h,'°C','color','k');

subplot(2,2,4);
m_contourf(lon_real,lat_real,winter_mean') 
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('冬季','fontsize',12); 
title(h,'°C','color','k');

其中，`gap`和`margins`分别设置subplot的间距和边距。`subtightplot`函数可以根据这些参数计算出合适的subplot位置。可以根据需要调整`gap`和`margins`的值。
