Conditional Line Chart Color

I am trying to have the points and the lines connecting them on my line graph be two different colors depending on a value i put in a column next to the chart values.

For example:
x y Variable
1 5 1
2 10
3 16 1
4 5

The points where there is a 1 in the variable column i would like to make a different color from the other points.

I did an extensive search and all i could find was the following:

Sub myChartClass_Calculate()
Dim cht As Object
Dim p As Object
Dim V As Variant
Dim Counter As Integer

However, this uses the values from the chart data, not an outside variable.
