Question

我正在尝试在tkinter canvas中绘制数据框。当我将kind用作 bar 时，该图看起来不错。但是当我将其更改为 line 时，xticks并不完全可见。

我希望下面的屏幕截图会有所帮助。

enter image description here

这是我使用的代码：

self.fig = Figure(figsize=(8, 4.6), dpi=100)
self.fig.subplots_adjust(top=0.93, bottom=0.19, right=0.97, left=0.17)
#self.fig.autofmt_xdate(rotation=30)
self.canvas = FigureCanvasTkAgg(self.fig, self)
self.canvas.get_tk_widget().place(x=400,y=240)
self.canvas.get_tk_widget().config(relief=tk.RAISED)
self.toolbar_frame = tk.Frame(master=self, height=20)
self.toolbar_frame.place(x=700,y=700)
self.toolbar = NavigationToolbar2Tk(self.canvas, self.toolbar_frame)
self.toolbar.update()
for button in self.toolbar.winfo_children():
    button.config(background='#464646')
self.ax = self.fig.add_subplot(111)
self.df.plot(x=self.labels[buttonID].cget('text'), ax=self.ax, kind="line")
self.ax.set_xticks(range(len(self.labels[buttonID].cget('text'))))
plt.setp(self.ax.get_xticklabels(), visible=True, rotation=30, ha='right')
self.canvas.draw()

Answer 1

Instead of default pandas plot

self.df.plot(x=self.labels[buttonID].cget('text'), ax=self.ax, kind="line")
self.ax.set_xticks(range(len(self.labels[buttonID].cget('text'))))

Use Matplotlib Pyplot:

self.ax.plot(self.df[self.labels[self.buttonIDcopy].cget('text')], self.df['Value'])

熊猫“线”图未显示所有Xticks
