回复 6楼ding3359的帖子
ding3359 你好，
1.我这边加载到 300000×10 行没有报错，请问你的错误信息是？
2.能否发个重现问题的 Demo 到论坛调试？
3.请使用以下代码进行测试：
- private void Form1_Load(object sender, EventArgs e)
- {
- StackedBarSeries stack = new StackedBarSeries();
- stack.LabelVisible = true;
- stack.YAxisId = 1;
- BarSeries series0 = new BarSeries();
- series0.Values.Add(8.0);
- series0.Values.Add(4.0);
- series0.Values.Add(2.0);
- series0.Values.Add(1.0);
- BarSeries series1 = new BarSeries();
- series1.Values.Add(2.0);
- series1.Values.Add(3.0);
- series1.Values.Add(4.0);
- series1.Values.Add(6.0);
- stack.Series.Add(series0);
- stack.Series.Add(series1);
- LineSeries series2 = new LineSeries();
- series2.PointMarker = new BuiltinMarker(MarkerShape.Circle, 7.0f);
- series2.Values.Add(8.0);
- series2.Values.Add(12.0);
- series2.Values.Add(14.0);
- series2.Values.Add(15.0);
- series2.YAxisId = 1;
- series2.LabelVisible = true;
- ValueAxis y2 = new ValueAxis();
- y2.AxisId = 1;
- y2.AutoMaximum = true;
- y2.AutoMinimum = true;
- y2.LabelVisible = true;
- y2.Location = AxisLocation.Far;
- YPlotArea plotArea = new YPlotArea();
- plotArea.Location = new PointF(0.2f, 0.2f);
- plotArea.Size = new SizeF(0.6f, 0.6f);
- plotArea.Series.Add(stack);
- plotArea.Series.Add(series2);
- plotArea.YAxes.Add(y2);
- LabelArea label = new LabelArea();
- label.Location = new PointF(0.5f, 0.02f);
- label.AlignmentX = 0.5f;
- label.AlignmentY = 0.0f;
- label.Text = "组合图表";
- ChartModel model = new ChartModel();
- model.LabelAreas.Add(label);
- model.PlotAreas.Add(plotArea);
- fpSpread1.ActiveSheet.Charts[0].Model = model;
- this.fpSpread1.ActiveSheet.Charts[0].ShowChartDesigner();
- }
