我绘制了一个2d直方图（来自ceo数据帧中的参数）：
binx=np.linspace(np.min(ceo.masa_z_Rmax),np.max(ceo.masa_z_Rmax),80)
biny=np.linspace(np.min(np.log10(ceo.SFR_Rmax)),np.max(np.log10(ceo.SFR_Rmax)),80)
median, bin_edges_zm, bin_edges_sfr, c=stats.binned_statistic_2d(ceo.masa_z_Rmax, np.log10(ceo.SFR_Rmax), values=ceo.met_g_Rmax, statistic='median', bins=[binx,biny])
median=np.nan_to_num(median,copy=True)
fig, ax = plt.subplots()
hist=ax.pcolormesh(binx, biny, median.T, norm=LogNorm(), cmap='viridis')
ax.set_xlabel(r'$\rm{\log(M_\ast)}$')
ax.set_ylabel(r'$\rm{\log{SFR}}$')
然后我想用从表中获取的另一个二维直方图进行绘图：
man_mass=np.linspace(9.1,11.35,16)
man_sfr=np.linspace(-1.45,0.8,16)
man_med=np.array([[0.,0.,0.,0.,0.,0.,0.,8.56,0.,0.,0.,0.,0.,0.,0.,0.],

hist=ax.pcolormesh(man_mass, man_sfr, man_med.T, norm=LogNorm(), cmap='viridis')
fig.colorbar(hist,ax=ax)
有了这个，我在颜色条上得到了具有不同最小和最大颜色的直方图。例如，在第一个绘制的直方图中，我得到9的深蓝色正方形，而在11中得到最亮的黄色，对于过度绘制的直方图，我得到8.5的深蓝色，而得到9.1的黄色。我有两个比例尺不同的颜色条（如果我想画的话）。 我想将两个直方图都映射到一个颜色条上，这样我绘制的直方图通常会更暗，并且可以对其计数进行真正的比较。 您可以帮我修改我的代码吗？
