Background

You have Point series and want to select a set of Points from the same. 

Steps to Accomplish

In this method, we will be selecting a set of Points from a series of Points. To make the selected points highlighted, we will make lines from those selected Points. Here Point1 is the set of points & it begins from left to right

Method 1 :

If we need to select first few points in a point series, we can do it by using the below expression

Point1.First(10)

This means, the selected points will be the first 10 points of the series (Point1[0] to Point1[9])

Method 2 :

If we need to select last few points in a point series, we can do it by the below expression

Point1.Last(5)

This means the selected points will be last 5 points of the series.

Method 3 :

If we need to select in between points in a point series, we can do it by the below expression

Point1.First(10).Last(6)

This means the selected points will be Point1[4] to Point1[9]. In this expression the starting of the selection of the point will be of point number 9, as 10 is an argument to the list method and the last 6 will be the number of points that will be taken in the set. That means, point 4, point 5, point 6... point 9 will be selected .
