graphcontrol |
A string whose value is the name of the graph in the DataWindow control. |

seriesnumber |
The number of the series in which you want the symbol type of a data point. |
|
datapointnumber |
The number of the data point for which you want the symbol type. |
|
symbolvariable |
In PowerBuilder, a variable of type grSymbolType in which you want to store the symbol type. For a list of values, see grSymbolType. |

Examples
These statements store the symbol for a data point in the variable symbol_type. The data point is the sixth point in the series named in the SingleLineEdit sle_series in the graph gr_depts in the DataWindow control dw_employees:
integer SeriesNbr
grSymbolType symbol_type
// Get the number of the series
SeriesNbr = dw_employees.FindSeries("gr_depts", &
sle_series.Text)
// Get the symbol
dw_employees.GetDataStyle("gr_depts", SeriesNbr, &
