Question

我在Layer Vector上具有PointFeature，在vectorLayer上具有LineString。我试图选择用于显示弹出窗口的点要素，然后也选择用于显示弹出窗口的lineString。但是，当我首先选择pointFeature时，无法选择lineString。

import matplotlib.pyplot as plt
import numpy as np
from fruits import friutchart

def main():
    fig = plt.figure()
    ax = fig.add_subplot(111)
    labels = ['Fruits', 'Vegetables','Pulses']
    size=[35, 20, 55]
    y_pos=np.arange(len(labels))    
    wedges = ax.bar(y_pos,size)
    plt.xlabel("Eatables")
    plt.ylabel("Count")
    plt.xticks(y_pos,labels)
    plt.title("FRUITS VEGETABLES AND PULSES COUNT")
    make_picker(fig,wedges)
    plt.show()

def make_picker(fig, wedges):
    def onclick(event):
        wedge = event.artist
        label = wedge.get_label()
        fruitchart()

    for wedge in wedges:
        wedge.set_picker(True)
    fig.canvas.mpl_connect('pick_event', onclick)

if __name__ == '__main__':
    main()

如何在不同向量中选择特征？
