I have the following code to make a plot of 4 different supply curves (economics).from matplotlib import pyplot as plt price = range(0,51) q1 = [x/2.0 for x in price] q2 = [x/4.0 for x in price] q3 = [x/5.0 for x in price] q4 = [x/10.0 for x in price] markers_on = [20, 40] plt.plot(q1,price,'b',q2,price,'g',q3,price,'r', q4, price, 'y' ) plt.title('Supply Curve') plt.xlabel('Quantity Supplied (Thousands per month') plt.ylabel('Price ($)') #plt.legend(('Kd = %d'%kd, 'Kd = %d'%kd2, 'Kd = %d'% kd3, 'Step'), loc=4) plt.legend(('p = 2Qs', 'p = 4Qs', 'p = 5Qs', 'p = 10Qs'), loc=4) plt.grid() plt.show() I would like to place markers on the 4 curves when the price is equal to $20 label it A, and when the price is equal to $40 and label it B. Does anyone know how I can accomplish this.
If this matplotlib.pyplot.text described here http://matplotlib.org/api/pyplot_api.html isn't any good I suggest you ask on the dedicated matplotlib users mailing list see https://lists.sourceforge.net/lists/listinfo/matplotlib-users
