如何增加 matplotlib 的 Y 轴限制？ [复制]

Question

def doAnchoreGraph(image):
    print(image)
    info = infoAnchoreLog(image)
    window = Toplevel()
    window.title('Report '+ image)
    window.geometry("1000x1000")
    data = {'CVE': ['1. CRITICAL','2. HIGH','3. MEDIUM','4. LOW'],
                'Frequency': [info[1],info[2],info[3],info[4]]
            }
    df = DataFrame(data,columns=['CVE','Frequency'])
        
    figure = plt.Figure(figsize=(9,8), dpi=100)
    ax = figure.add_subplot(111)
    bar = FigureCanvasTkAgg(figure, window)
    bar.get_tk_widget().pack(side=tk.LEFT, fill=tk.BOTH)
    df = df[['CVE','Frequency']].groupby('CVE').sum()
    df.plot(kind='bar', legend=True, ax=ax)
    ax.set_title("Scanned Image: "+ image)
    
    filename = "anchorescan-" + image + ".png" 
    figure.savefig(filename)

有人知道如何增加Y轴的极限吗？由于某种原因，我的上限为 20。这是我的示例输出： doAnchoreGraph.png

Answer 1

ax.set_ylim(start,end) 应该可以解决问题。
