在每个子图旁边设置颜色条的大小

Question

我在写我的科学文章，我的副标题有问题。 不幸的是，我得到的色条比图形要高得多。你知道吗

我读了这篇文章：Matplotlib: same height for colorbar as for plot

但我没有找到一种方法来覆盖我的脚本，以调整我的颜色栏。你知道吗

这是我的脚本和我的调整大小尝试：

fig3, (ax1, ax2, ax3) = plt.subplots(1,3)

fig = plt.gcf()
fig.set_size_inches(16, 9)

convolution_locale = convolve(RotatePlot, Gaussian2DKernel(stddev=4)) # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE POUR 2'
fig_smoothed_heatmap_locale = ax1.imshow(convolution_locale, interpolation='nearest')
ax1.set_title("Carte de densite convoluee 2'")
ax1.set_xlabel("X (arcmin)")
ax1.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax1)
cax1 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_heatmap_locale,cax=cax1)
ax1.invert_yaxis()


convolution_grande = convolve(RotatePlot, Gaussian2DKernel(stddev=32)) # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE POUR 8'
fig_smoothed_heatmap_grande = ax2.imshow(convolution_grande, interpolation='nearest')
ax2.set_title("Carte de densite convoluee 16'")
ax2.set_xlabel("X (arcmin)")
ax2.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax1)
cax2 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_heatmap_grande,cax=cax2)
ax2.invert_yaxis()

convolution_diff = convolution_locale - convolution_grande # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE 2' - 8'
fig_smoothed_tab_diff = ax3.imshow(convolution_diff, interpolation='nearest')
ax3.set_title("Carte 2' - Carte 16'")
ax3.set_xlabel("X (arcmin)")
ax3.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax1)
cax3 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_tab_diff,cax=cax3)
ax3.invert_yaxis()

# Create space for labels between subplots
fig3.tight_layout()

fig3.savefig(outname3)

这就是我得到的：

如果你有解决办法，谢谢你！：）

Answer 1

问题是在创建3divider实例时总是使用ax1。你知道吗

将第二个和第三个dividers改为使用ax2和ax3，例如：

divider = make_axes_locatable(ax2)

这是你的整个剧本，有固定的台词：

fig3, (ax1, ax2, ax3) = plt.subplots(1,3)

fig = plt.gcf()
fig.set_size_inches(16, 9)

convolution_locale = convolve(RotatePlot, Gaussian2DKernel(stddev=4)) # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE POUR 2'
fig_smoothed_heatmap_locale = ax1.imshow(convolution_locale, interpolation='nearest')
ax1.set_title("Carte de densite convoluee 2'")
ax1.set_xlabel("X (arcmin)")
ax1.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax1)
cax1 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_heatmap_locale,cax=cax1)
ax1.invert_yaxis()


convolution_grande = convolve(RotatePlot, Gaussian2DKernel(stddev=32)) # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE POUR 8'
fig_smoothed_heatmap_grande = ax2.imshow(convolution_grande, interpolation='nearest')
ax2.set_title("Carte de densite convoluee 16'")
ax2.set_xlabel("X (arcmin)")
ax2.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax2)          ### I changed this line
cax2 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_heatmap_grande,cax=cax2)
ax2.invert_yaxis()

convolution_diff = convolution_locale - convolution_grande # AFFICHAGE DE LA CARTE DE DENSITE CONVOLUEE 2' - 8'
fig_smoothed_tab_diff = ax3.imshow(convolution_diff, interpolation='nearest')
ax3.set_title("Carte 2' - Carte 16'")
ax3.set_xlabel("X (arcmin)")
ax3.set_ylabel("Y (arcmin)")
divider = make_axes_locatable(ax3)          ### I changed this line too
cax3 = divider.append_axes("right", size="5%", pad=0.05)
fig3.colorbar(fig_smoothed_tab_diff,cax=cax3)
ax3.invert_yaxis()

# Create space for labels between subplots
fig3.tight_layout()

fig3.savefig(outname3)
