我试图在pyspark中使用matplotlib绘制条形图，但出现错误。
package org.foo;
public class AnAspect {
public static void main(String[] args) {
new AB().handle(null);
new BC().handle(null);
new AC().handle(null);
}
}
aspect AnAspect1 {
declare parents : AB extends ASupport;
// can only insert a class into hierarchy, but org.foo.BSupport is not a subtype of org.foo.CSupport
declare parents : ASupport extends BSupport;
}
aspect AnAspect2 {
declare parents : BC extends BSupport;
declare parents : BSupport extends CSupport;
}
aspect AnAspect3 {
declare parents : AC extends ASupport;
declare parents : ASupport extends CSupport;
}
class BC extends MyCallback {

class AC extends MyCallback {

System.out.println("ASupport");
super.handle(o);
}
}

import matplotlib.pyplot as plt
%matplotlib inline
x_labels = violationcode_freq['Violation Code'].values
fig = violationcode_freq[['count']].plot(kind='bar', facecolor='lightblue')
fig.set_xticklabels(x_labels)
fig.set_title('Counts of trips by passenger count')
fig.set_xlabel('Passenger count in trips')
fig.set_ylabel('Trip counts')
plt.show()
