line类型的graph数据窗口，那些点能不能设置，比如它默认是个矩形、×号。那个能自己设置么，特别它默认的好大一个，很难看，怎么调呢
------解决方案--------------------
- C# code
int idw_gr.setredraw(false)for i = 1 to dw_gr.SeriesCount("gr_1") //你的数据窗口中，实际可能不是gr_1 //NoSymbol!可以换成其他，具体查看帮助 dw_gt.SetSeriesStyle('gr_1', dw_gr.SeriesName('gr_1',i), NoSymbol!)nextdw_gr.setredraw(true)
------解决方案--------------------
修改符号类型
dwcontrol.SetSeriesStyle ( string graphcontrol, string seriesname, grSymbolType symbolvalue )
NoSymbol! 0 None
SymbolHollowBox! 1 A hollow box
SymbolX! 2 An X
SymbolStar! 3 A star
SymbolHollowUpArrow! 4 An outlined up arrow
SymbolHollowDownArrow! 5 An outlined down arrow
SymbolHollowCircle! 6 An outlined circle
SymbolHollowDiamond! 7 An outlined diamond
SymbolSolidBox! 8 A filled box
SymbolSolidDownArrow! 9 A filled down arrow
SymbolSolidUpArrow! 10 A filled up arrow
SymbolSolidDiamond! 11 A filled diamond
SymbolSolidCircle! 12 A filled circle
SymbolPlus! 13 A plus sign
dw_1.SetSeriesStyle("gr_1", "F", SymbolSolidCircle! ) 修改成圆点

好像可以不要，想设置成别的不行
