My data model coming from database is as below:

Max, Average, Min, Point1, Point2, Point3, Point4

I wanted to create two layers to create a composite Candlestick chart as attached file.

I created two series. One series is based on Max, Min and Avrage for creating Candlestick item. And second series is based on Point1 to Poin3 to create each point on surface of each candlestick item.

I ordered Point1 to Point3 and created 3 calculated values for each one based on subtracting from minimum value between Point1 to Point3.

I mean:

For each record:

Minvalue=Min(Point1,Point2,Poin3)

calculatedPoint1=Point1- Minvalue

calculatedPoint2=Point2- Minvalue

calculatedPoint3=Point3- Minvalue

 And then I put them (calculatedPoints) correctly on surface of each candlestick item. But unfortunately I was unable to create a legend for those points for chart. Because each point is a calculated point for each candlestick item and I don’t know which point is Point1 or Point2. Please give me some advice how can access to colour of each point and put a correct colour number to each point on surface of relevant  candlestick item.
