“ plugins.InteractiveLegendPlugin（）”未完全显示图例

Question

我正在尝试使用plugins.InteractiveLegendPlugin（）可视化交互式绘图。但是，并非所有图例（从1到50的数字）都完整显示（仅显示1到19）。然后，我尝试使用fig.subplots_adjust(right=0.7, top=1)调整图形，现在它显示更多的图例（1到21）。但仍然不完全，而且再也无法更改调整。

import mpld3
from mpld3 import plugins
from mpld3.utils import get_id
import collections

partial = df_mobile.iloc[::100, :]

img = plt.imread("StHimarkNeighborhoodMapNoLabels.png")

fig,ax = plt.subplots()
fig.set_size_inches(14,8,forward=True)
fig.suptitle("Location of Pollution", fontsize=20)
fig.subplots_adjust(right=0.7, top=1)

ax.imshow(img, extent=[-120, -119.711, 0, 0.2385])

plt.ylabel("Latitude",fontsize=15)
plt.xlabel("Longtitude",fontsize=15)

for val in range(1,51):
    partial_filtered = partial[partial['Sensor-id']==val].filter(items=['Long','Lat'])
    vis = ax.plot(partial_filtered['Long'], partial_filtered['Lat'].T, lw=2, alpha=0.8, label=val)
    handles, labels = ax.get_legend_handles_labels()


plt.grid()


interactive_legend = plugins.InteractiveLegendPlugin(zip(handles,
                                                          labels),
                                                      labels,
                                                      alpha_unsel=0.5,
                                                      alpha_over=1.5, 
                                                      start_visible=True)
plugins.connect(fig, interactive_legend)


plt.gca().set_ylim(0, 0.2385)
plt.gca().set_xlim(-120, -119.711)

mpld3.display()
