Are there text / number input fields in matplotlib?

Question

Are there text and / or numeric input fields for matplotlib ?

I saw the Slider widget, but it's something else. I want a simple number entry field.

Answer 1

There are currently no widgets that could be used to enter numbers as text. If you had a small selection of discrete numbers, you could use RadioButton , or you could use a slider, as you said.

It would be best to create a complete graphical interface using Tkinter . This will allow you to add any GUI elements that you need. It is also possible to embed matplotlib graphics in Tkinter, as shown in the two examples here and.

Answer 2

You are looking for an interactive TextBox widget that was added in 2.1:

 import numpy as np import matplotlib.pyplot as plt from matplotlib.widgets import TextBox fig, ax = plt.subplots() plt.subplots_adjust(bottom=0.2) t = np.arange(-2.0, 2.0, 0.001) ydata = t ** 2 initial_text = "t ** 2" l, = plt.plot(t, ydata, lw=2) def submit(text): ydata = eval(text) l.set_ydata(ydata) ax.set_ylim(np.min(ydata), np.max(ydata)) plt.draw() axbox = plt.axes([0.1, 0.05, 0.8, 0.075]) text_box = TextBox(axbox, 'Evaluate', initial=initial_text) text_box.on_submit(submit) plt.show()
