Matplotlib - Textbox Widgets Last Updated : 17 Feb, 2022 Comments Improve Suggest changes Like Article Like Report In this article, we are going to see matplotlib's textbox widget. Matplotlib is a plotting library for the Python programming language. In this article, we will try to plot a graph for different powers(e.g. t^2, t^3, t^9, etc.) using textbox widget. The Textbox is a widget that accepts input from the user. Input can also be formulas so that we can generate a graph based on those formulas. To use this widget we use TextBox() function. It accepts two parameters Figure i.e. graph to use.Text to display with textbox i.e. Label to textBox. Below is the implementation of this widget: Python # Import modules import numpy as np import matplotlib.pyplot as plt from matplotlib.widgets import TextBox # Adjust illustration fig, ax = plt.subplots() fig.subplots_adjust(bottom=0.2) t = np.arange(-4.0, 4.0, 0.01) l, = ax.plot(t, np.zeros_like(t), lw=2) # Function to plot graph # according to expression def visualizeGraph(expr): ydata = eval(expr) l.set_ydata(ydata) ax.relim() ax.autoscale_view() plt.draw() # Adding TextBox to graph graphBox = fig.add_axes([0.1, 0.05, 0.8, 0.075]) txtBox = TextBox(graphBox, "Plot: ") txtBox.on_submit(visualizeGraph) txtBox.set_val("t**5") # Plot graph plt.show() Output: Explanation: In the above program, we created a graph for t2 as by default graph. In txtBox labelled as Plot: we can enter the formula we want to view the graph for.
