[FIXED] Plot a 2D graph from a .csv file with special form in Python

Issue

I am reviewing the following discussion:
Plot a 2D graph from a csv file using matplotlib in Python in ubuntu

We use the code

np.loadtxt('text.csv', delimiter=',')

I believe this assumes that the data we want starts at the 1st row of .csv file.

My question is that if the data we want starts at, for example 5th row of .csv file.

For example

1. #Title 1 
2. #Explanation 2
3. #Explanation 3
4. #Explanation 4
5. 1                      3.7
6. 1.1                    4.2
7. 1.2                    5.3
.
.
.

The data we want to plot start at the 5th row. Then how to modify the code above to correctly plot the contents in that .csv file?

Thanks!

Solution

You have to specify the skiprows parameter (documentation):

np.loadtxt('text.csv', delimiter=',', skiprows=N)
