CBCGPChartStockSeries

Detailed Description

The CBCGPChartStockSeries implements the functionality of a series used to display financial data in OHLC format.

You can display a stock series as:

• ohlc bars
• candlesticks
• line built on open, high, low, close values or custom.

You can set the series display type by calling CBCGPChartStockSeries::SetStockSeriesType. In the line mode you can customize the displayed values for each data point by specifying a custom callback (CBCGPChartStockSeries::SetCustomStockValueCallback) or overriding CBCGPChartStockSeries::GetCustomStockValue.

If you need to create a virtual series reading the data from an external storage you have to derive a class from CBCGPChartStockSeries and override the following methods:

• CBCGPChartStockSeries::IsOptimizedLongDataMode, which should return TRUE
• CBCGPChartStockSeries::GetDataPointCount, which should return the number of data points in the external storage
• CBCGPChartStockSeries::GetStockDataAt, which should return OHLC values and corresponding date/time located at the specified index.

Please take a look at ChartStockView.cpp and ChartStockRTView.cpp (BCGPChartExample) for more information about implementation of static and real time stock charts.
