有没有办法将图表控件复制到新表单?我有一个带有图表控件的 Windows 窗体,但该窗体不允许调整大小。出于这个原因,我有一个“缩放”按钮,它以可调整大小的新形式打开图表。我在“原始”图表中设置了很多图表属性(轴颜色、轴间隔等),并且想重用这些属性。我试图用图表作为参数调用新表单的构造函数,但这不起作用。
public ZoomChartSeriesForm(Chart myChart)
我的主要问题是,当我只复制图表时,我允许在图表内部进行缩放并且崩溃。
这是我的“原始图表”的代码(示例):
System.Drawing.Color color = System.Drawing.Color.Red;
//plot new doublelist
var series = new Series
{
Name = "Series2",
Color = color,
ChartType = SeriesChartType.Line,
ChartArea = "ChartArea1",
IsXValueIndexed = true,
};
this.chart1.Series.Add(series);
List<double> doubleList = new List<double>();
doubleList.Add(1.0);
doubleList.Add(5.0);
doubleList.Add(3.0);
doubleList.Add(1.0);
doubleList.Add(4.0);
series.Points.DataBindY(doubleList);
var chartArea = chart1.ChartAreas["ChartArea1"];
LabelStyle ls = new LabelStyle();
ls.ForeColor = color;
Axis a = chartArea.AxisY;
a.TitleForeColor = color; //color of axis title
a.MajorTickMark.LineColor = color; //color of ticks
a.LabelStyle = ls; //color of tick labels
chartArea.Visible = true;
chartArea.AxisY.Title = "TEST";
chartArea.RecalculateAxesScale();
chartArea.AxisX.Minimum = 1;
chartArea.AxisX.Maximum = doubleList.Count;
// Set automatic scrolling
chartArea.CursorX.AutoScroll = true;
chartArea.CursorY.AutoScroll = true;
// Allow user to select area for zooming
chartArea.CursorX.IsUserEnabled = true;
chartArea.CursorX.IsUserSelectionEnabled = true;
chartArea.CursorY.IsUserEnabled = true;
chartArea.CursorY.IsUserSelectionEnabled = true;
// Set automatic zooming
chartArea.AxisX.ScaleView.Zoomable = true;
chartArea.AxisY.ScaleView.Zoomable = true;
chartArea.AxisX.ScrollBar.IsPositionedInside = true;
chartArea.AxisY.ScrollBar.IsPositionedInside = true;
//reset zoom
chartArea.AxisX.ScaleView.ZoomReset();
chartArea.AxisY.ScaleView.ZoomReset();
chart1.Invalidate();
