By default, a legend is drawn surrounded by a filled rectangle with a shadow. This means that the flag indicating whether the legend is surrounded by a frame is set to IlvTrue and the flag indicating whether the legend is drawn without a background and a shadow is set to IlvFalse.

When a legend object is created, it does not contain any legend items. Since the property “Automatically Recomputed” is set to IlvTrue by default, the legend items corresponding to the displayers defined in a chart will be computed automatically and added to the legend when the legend is set on the chart. Also, the legend items are rearranged when the legend is resized, when the inner spacing of the legend is modified, and so on. New legend items are also added automatically and arranged when new displayers are added to the chart.

By default, the legend is resized automatically to fit the legend items that it contains because the property “Automatically Fit to Contents” is set to IlvTrue. If you do not want the size of the legend to be systematically recomputed from the legend items, you have to set the property “Automatically Fit to Contents” to IlvFalse.
