### Method 3 : OpenCV sample style !!
There is a [sample code for color-histogram in OpenCV-Python2
samples](https://github.com/Itseez/opencv/blob/master/samples/python2/color_histogram.py). If you
run the code, you can see the histogram shows the corresponding color also. Or simply it outputs a

In that code, the author created a color map in HSV. Then converted it into BGR. The resulting
histogram image is multiplied with this color map. He also uses some preprocessing steps to remove

Well, here you adjust the values of histograms along with its bin values to look like x,y
coordinates so that you can draw it using cv2.line() or cv2.polyline() function to generate same
