Sequential color background

[swisha]

What code do I use to change the color background of a radar chart.
I want to use a sequential color scheme from light blue to dark blue.
I assume that the starting point would be from matplotlib.pyplot using the cmaps.

Any help is appreciated.

Here is an example where I would like to change the background.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78

# Plots a radar chart.   from math import pi import matplotlib.pyplot as plt     # Set data cat = ['Speed', 'Reliability', 'Comfort', 'Safety', 'Effieciency'] values = [90, 60, 65, 70, 40]   N = len(cat)   x_as = [n / float(N) * 2 * pi for n in range(N)]   # Because our chart will be circular we need to append a copy of the first # value of each list at the end of each list with data values += values[:1] x_as += x_as[:1]     # Set color of axes plt.rc('axes', linewidth=0.5, edgecolor="#888888")     # Create polar plot ax = plt.subplot(111, polar=True)     # Set clockwise rotation. That is: ax.set_theta_offset(pi / 2) ax.set_theta_direction(-1)     # Set position of y-labels ax.set_rlabel_position(0)     # Set color and linestyle of grid ax.xaxis.grid(True, color="#888888", linestyle='solid', linewidth=0.5) ax.yaxis.grid(True, color="#888888", linestyle='solid', linewidth=0.5)     # Set number of radial axes and remove labels plt.xticks(x_as[:-1], [])   # Set yticks plt.yticks([20, 40, 60, 80, 100], ["20", "40", "60", "80", "100"])     # Plot data ax.plot(x_as, values, linewidth=2, linestyle='solid', zorder=3)   # Fill area ax.fill(x_as, values, 'b', alpha=0.0)     # Set axes limits plt.ylim(0, 100)     # Draw ytick labels to make sure they fit properly for i in range(N):     angle_rad = i / float(N) * 2 * pi       if angle_rad == 0:         ha, distance_ax = "center", 10     elif 0 < angle_rad < pi:         ha, distance_ax = "left", 1     elif angle_rad == pi:         ha, distance_ax = "center", 1     else:         ha, distance_ax = "right", 1       ax.text(angle_rad, 100 + distance_ax, cat[i], size=10, horizontalalignment=ha, verticalalignment="center")     # Show polar plot plt.show()

this may be indirectly linked to your request.
It may be of value since the code is presented, and you can see how background color was applied as a style:
