问题描述
我希望使用鼠标自动绘制数据，而无需单击来自 DZT 文件".我创建了一个程序来绘制数据，如下图所示:
正如你在这张图片中看到的，x 轴从 0 到 3525 ans，每个 x 是一个信号，所以我有超过 3500 个信号来制作这张图.
例如，如果我想看到 x=999 的信号，它看起来像这样.
我真正想做的是每次当我通过鼠标而不点击图形时，它应该自动绘制它的信号.
我尝试了很多方法，但我不知道该怎么做.
感谢您的帮助
这是我的文件:
I'm looking to plot Data automatically using mouse without clicking From a DZT file.i Created a program in order to plot data as you can see in this graph:
As you can see in this picture, x axes going from 0 to 3525 ans every x is a signal so i have more than 3500 signals making this graph.
for exemple if i want to see the signal of x=999, it looks like this.
what i want really to do is every time when i pass my mouse without clicking on the graph it should plot it's signal automatically .
i try to use a lot of methods but rally i dont know how to do it.
i'll be grateful for your help

This is my program:

Resources_frame = LabelFrame(root, bd=2, relief=GROOVE, text="Conversion Area")
Resources_frame.place(x=5, y=5, width=250, height=80)
lbl_ra = Label(Resources_frame, text="Select your File ")
lbl_ra.grid(row=0, column=0, sticky=W)
lbl_ra = Label(Resources_frame, text="Convert Selected file ")
lbl_ra.grid(row=1, column=0, sticky=W)

def ReadDZT():
file_path = filedialog.askopenfilename()
file_name, file_extension = os.path.splitext(file_path)
print(file_extension)
if file_extension == '.DZT':
messagebox.showinfo("INFO", "Your DZT File Has Been Selected Successfully")
hdr, arrs, gps = readgssi.readgssi(infile=file_path, verbose=True)
TimeRange = hdr['rhf_range']
Samples = hdr['rh_nsamp']
X_Axes = np.array(range(0, Samples))
xAxes = X_Axes[2::1]
df = pd.DataFrame(arrs[0])
Data = df.iloc[2::1, 0::1]
fig2 = plt.figure()
plt.plot(xAxes, Data[999])
plt.show()
fig = plt.figure()
plt.imshow(Data, aspect='auto', cmap='bone')
plt.show()
elif file_extension == '.csv':
messagebox.showinfo("INFO", "Your CSV File Has Been Selected Successfully")
df = pd.read_csv(file_path)
NumberOfSimples = df.iloc[2::1, 0]
Data = df.iloc[::1, ::1]
DataAScan = df.iloc[2::1, 999]
fig1 = plt.figure()
plt.plot(NumberOfSimples, DataAScan)
plt.show()
fig2 = plt.figure()
plt.imshow(Data, aspect='auto', cmap='bone')
plt.show()

messagebox.showwarning("WARNING", "You Have Been Selected a Different Format")
# =============Resources Buttons================#

root.mainloop()
As indicated in the previous question Ploting a graph automatically using mouse coordinate (and I think this question should have been an edit of it), the mouse motion can be monitored with plt.connect('motion_notify_event', mouse_move). The slice of Data to be plotted in fig2 simply corresponds to the x-coordinate of the mouse, that is Data[int(event.xdata)] in mouse_move(event).
Therefore, in mouse_move(event), you:
- Clear the axis:
ax2.clear()(whereax2is theAxesSubplotobject offig2) - Plot the slice
ax2.plot(self.xAxes, self.Data[int(event.xdata)]) - Update the figure
fig2.canvas.draw_idle()
However, I had issues with using simultaneously the matplotlib figures and the tkinter GUI because of the separate event loops. Therefore I embedded the figures in the tkinter GUI directly (see e.g. https://matplotlib.org/3.4.0/gallery/user_interfaces/embedding_in_tk_sgskip.html).
I also put the graph related code in a class to keep the loaded data in attributes to avoid using global variables.
