grType has no action on the chart if this parameter corresponds to the current type of chart. 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.
