如何设置波形图样式

登录

问题描述：添加波形图后，Spread 会有默认的填充色，如何通过代码指定填充色。
问题解答：波形图提供了FirstMarkerColor等相关属性用于定制填充颜色。
关键代码：

private void AddSparkLines()
{
FarPoint.Win.Spread.SheetView sv = new FarPoint.Win.Spread.SheetView();
FarPoint.Win.Spread.Chart.SheetCellRange data = new FarPoint.Win.Spread.Chart.SheetCellRange(sv, 0, 0, 1, 5);
FarPoint.Win.Spread.Chart.SheetCellRange data2 = new FarPoint.Win.Spread.Chart.SheetCellRange(sv, 5, 0, 1, 1);
FarPoint.Win.Spread.ExcelSparklineSetting ex = new FarPoint.Win.Spread.ExcelSparklineSetting();
ex.AxisColor = Color.SaddleBrown;
ex.ShowFirst = true;
ex.ShowHigh = true;
ex.ShowLow = true;
ex.ShowLast = true;
//自定义填充色
ex.FirstMarkerColor = Color.Blue;
ex.HighMarkerColor = Color.DarkGreen;
ex.MarkersColor = Color.Aquamarine;
ex.LowMarkerColor = Color.Red;
ex.LastMarkerColor = Color.Orange;
ex.ShowMarkers = true;
fpSpread1.Sheets[0] = sv;
sv.Cells[0, 0].Value = 2;
sv.Cells[0, 1].Value = 5;
sv.Cells[0, 2].Value = 4;
sv.Cells[0, 3].Value = 1;
sv.Cells[0, 4].Value = 3;
fpSpread1.Sheets[0].AddSparkline(data, data2, FarPoint.Win.Spread.SparklineType.Line, ex);
#endregion
}
