I am creating a plot with matplotlib
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0, 5, 0.1);
y = np.sin(x)
plt.plot(x, y)
Can I flip the plot, making the y-axis inverted and all positive values negative and vice versa?
I know I can multiply by -1 and use invert_yaxis but I wonder if there is a function for flipping it without changing the values.

Matplotlib invert x and y axis By using invert_xaxis() and invert_yaxis() method we can flip the x-axis and y-axis respectively. In the above example, we import numpy and matplotlib libraries.
Most common method is by using invert_xaxis() and invert_yaxis() for the axes objects. Other than that we can also use xlim() and ylim(), and axis() methods for the pyplot object. To invert X-axis and Y-axis, we can use invert_xaxis() and invert_yaxis() function.
The plt. axis() method allows you to set the x and y limits with a single call, by passing a list which specifies [xmin, xmax, ymin, ymax] : In [11]: plt.
Try the following function:
plt.gca().invert_yaxis()
