 Stem Plot
 =========
 
-Example stem plot.
+Stem plot plots vertical lines from baseline to the y-coordinate
+Plotting cosine(x) w.r.t x, using '-.' as the pattern
+for plotting vertical lines

 x = np.linspace(0.1, 2 * np.pi, 10)

+# setting property of baseline with color red and linewidth 2
 plt.setp(baseline, color='r', linewidth=2)
