There are two solutions to this:

1. Make the variables public properties - though there are issues around the use of lists so having a ReadOnlyCollection wrapper is the way to solve this.

2. Create a public method that performs the required manipulations on the lists.

For example to add a point to the list you'd have:

public void AddValueToX(float value)
{
    PointX.Add(value);
}

If you wanted to test whether a value was in the list (which is fraught with danger as you are dealing with single precision values):

public bool InListX(float value)
{
    // A test on value vs the data in Point_X allowing for floating point inaccuracies
}
