Hi,
Since NullHandling is not available to all chartTypes I would like to simulate the behavior for other charts by passing in appropriate data.
Regarding this... how is a missing value determined for NullHandling.InterpolateSimple when subsequent value is missing data as well in the following formula
interpolatedValue = (precedingValue / 2) + (subsequentValue / 2) // this is the formula Infragistics uses to calculate missing data
Thanks

Hi Max,
Thanks a lot for your reply and explanation. Works great.
When the chart sees a null value it will see what the latest and the next available non-null values are. It will then replace each null value with an interpolated value based on the above formula. To make this clearer, I'll use an example. For the data values {10, 20, null, null, null, 40} interpolateSimple option will give you the following result: {10, 20, 30, 35, 37.5, 40}, so the first null is (20+40)/2, the second null is (30+40)/2, etc.
