Using Collections in C++

Many 2D Chart objects are organized into collections. For example, the chart axes are organized into the Axes collection.

To access a particular element of a collection, specify the index which uniquely identifies this element. For example, the following code changes the maximum value of the X axis to 25.1:

Caxis axisX(m_chart.GetChartArea().GetAxes().GetItem(COleVariant("x")));

axisX.GetMax().SetValue(25.1);

Note that the index 1 refers to the first element of a collection.
