基本用法
import matplotlib.pyplot as plt obj_list = obj_list[:100] x_axis = range(len(obj_list)) y_axis = [] for x in obj_list: y_axis.append(x[1]) plt.figure(figsize=(16,10)) rects = plt.bar(left=x_axis, height=y_axis, width=0.6, color='red') #plt.xticks(range(len(label_list)), label_list, fontsize=8) #plt.title('motif num') plt.legend() # for rect in rects: # height = rect.get_height() # plt.text(rect.get_x() + rect.get_width() / 2, height+1, str(height), ha="center", va="bottom") plt.grid(True) plt.show()
