Remarks

Changing the type of chart

When changing the type of chart, the parameters of the former chart that cannot be reproduced in the new chart are reinitialized.
Changing the type of chart may produce unexpected effects. For example, when a Pie chart (grPie constant) is changed into a Scatter chart (grScatter constant), all the points are aligned on the X-axis (horizontal axis).
The type of chart can be changed in the context menu. However, the display options produce different visual effects for each type of chart.
The parameters defined by grType will be taken into account during the next call to grDraw.
