CBCGPChartValue

Detailed Description

The CBCGPChartValue class implements the functionality of a chart value.

It provides in-place conversion to double and can be empty if the value is not set. Use CBCGPChartValue::SetEmpty to set empty state. Call CBCGPChartValue::IsEmpty to determine whether a chart value is empty.

Each data point maintains an underlined CBCGPChartData object, which is built up from chart values.
