James,
Can you please explain what do you mean by the columns between 4 – 8?
Since each line in your CSV is in the format:
["11/13/2017 00:10:00", "0", "69.8", "1.53", "0", "0.0", "0.0", ""]
you can access the columns between 4 & 8 i.e. columns 5, 6, & 7 by accessing the array elements points[4], points[5] & point[6] respectively. But in your CSV data all these columns are zero.
Also x: parseFloat(points[0])
won’t work as expected as the first element in the array of your CSV data is a date-time value.
Please create a jsfiddle and brief us more about your requirement so that understand you requirement better and help you out.
