tchart

我用的是C# 从网上看到资料拷贝过来备忘,共同学习下:

  • 设置chart标题:axTChart1.Header.Text.Add("标题");
  • 修改标题:axTChart1.Header.Text.set_Item(index, "修改后的标题");
  • 表头标题清除: axTChart1.Header.Text.Clear();
  • 移除第n(int)个标题:axTChart1.Header.Text.Remove(1);
  • 标题居中:axTChart1.Header.Alignment = TeeChart.ETitleAlignment.taCenter;
  • 标题向右移动50:axTChart1.Header.CustomPosition = true;

                    axTChart1.Header.Left= axTChart1.Header.Left + 50;

  • 标题背景:axTChart1.Header.Transparent = false;//背景不透明

                   axTChart1.Header.Brush.Style = TeeChart.EBrushStyle.bsBackCrossSmall;//背景样式

  • 标题背景阴影颜色:axTChart1.Header.Transparent = false;

                   axTChart1.Header.ShadowColor=(uint)(1255);

说明(Legend):

  • 说明是否可见:axTChart1.Legend.Visible = true;
  • 说明框内分割线是否可见:axTChart1.Legend.DividingLines.Visible = true;
  • 说明框分割线颜色:axTChart1.Legend.Color=(uint)(2201);
  • 说明框向下移位(量50):TChart1.Legend.TopPos =50
  • 说明框内图示的长度:axTChart1.Legend.ColorWidth = 150;
  • 说明框内文字颜色:axTChart1.Legend.Font.Color = (uint)(130000);
  • 说明框阴影部分的颜色和深度:axTChart1.Legend.ShadowColor=(uint)(13000);

                                            axTChart1.Legend.ShadowSize = 6;

面板(Panel):

  • 载入面板背景图片:axTChart1.Panel.BackImageLoad(@"e:121.jpg");
  • 面板斜度设置:
1
2
3
4
axTChart1.Panel.Gradient.Visible = true;
axTChart1.Panel.Gradient.StartColor = (uint)(1);
axTChart1.Panel.Gradient.EndColor = (uint)(13000);
axTChart1.Panel.Gradient.Direction = TeeChart.EGradientDirection.gdFromTopLeft;

3D效果:

  • 隐藏3D效果:axTChart1.Aspect.View3D = false;

Chart分页:

  • 运行时显示ChartEditor对话框:axTChart1.ShowEditor();
  • 每一页最多可以显示的点的数量:axTChart1.Page.MaxPointsPerPage = 20;
  • 下一页&&上一页(这时需要设置一个按钮来完成): axTChart1.Page.Next();

axTChart1.Page.Previous();

  • 跳到最后一页:axTChart1.Page.Current = axTChart1.Page.Count;
  • 决定最后一页放缩:axTChart1.Page.ScaleLastPage = false;
  • 获取当前页码:MessageBox.Show(axTChart1.Page.Current.ToString());

坐标(Axis):

  • 添加20个点到序列上:
    1
    2
    3
    4
    5
    6
    7
    for (int i = 1; i <= 20; i++)
     
    {
     
    axTChart1.Series(1).Add(i*i, i.ToString(), (uint)(50000));
     
    }
  • 设置轴刻度(Y轴为Axis.Left ,X轴为Axis.Bottom)
  • 设置Y轴的终点和起点,最小刻度值:
1
2
3
4
axTChart1.Axis.Left.Automatic = false;//必须有,或者用.AutomaticMaximum等代替
axTChart1.Axis.Left.Maximum = 600;//最大值的声明必须在最小值先,否则报错
axTChart1.Axis.Left.Minimum = 500;
axTChart1.Axis.Left.Increment = 20;
  • 将Y轴最小值固定,最大值自动增长:出现严重错误
  • 将Y轴最大值固定,最小值自动时应:
1
2
3
axTChart1.Axis.Left.AutomaticMaximum = false;
axTChart1.Axis.Left.Maximum = 600;
axTChart1.Axis.Left.AutomaticMinimum = true;

(* 结论: 在设置最大最小值时,没设置最大值就设置最小值将失败)

自定义轴标签(添加轴事件):

1
2
3
private void axTChart1_OnGetAxisLabel(object sender, AxTeeChart.ITChartEvents_OnGetAxisLabelEvent e) {
e.labelText = "p" + e.valueIndex.ToString();
}

设置轴自定义标签:

1
2
3
4
axTChart1.Axis.Left.Logarithmic = true;
axTChart1.Axis.Left.Increment = 0;//默认为0
axTChart1.Axis.Left.SetMinMax(0, 10000);
axTChart1.Axis.Left.Labels.ValueFormat = "#e+0";

自定义交叉坐标轴:只能在chart Editor中设置。

坐标轴点击事件

1
2
3
4
5
private void axTChart1_OnClickAxis(object sender, AxTeeChart.ITChartEvents_OnClickAxisEvent e)
{
MessageBox.Show(axTChart1.Axis.Bottom.CalcPosPoint(e.x).ToString());//显示位置
 
}

Series:

  • 删除第5个点(从0开始):axTChart1.Series(0).Delete(5);
  • 添加一个坐标:axTChart1.Series(0).AddNull("label");
  • 添加一个Series:
1
2
3
4
TeeChart.ESeriesClass ns = new TeeChart.ESeriesClass();
int index = axTChart1.AddSeries(ns);
axTChart1.Series(index).HorizontalAxis = TeeChart.EHorizontalAxis.aTopAxis;
axTChart1.Series(index).VerticalAxis = TeeChart.EVerticalAxis.aRightAxis;
  • 设置series1的数据源为series0:
1
2
axTChart1.Series(1).DataSource = "Series0";
axTChart1.Series(1).SetFunction(TeeChart.EFunctionType.tfCopy);
  • 交换两个Series的顺序:
1
axTChart1.ExchangeSeries(0, 1); //After exchanging Series, the index for the Series will be changed.
  • 显示第三个位置的Y值:MessageBox.Show(axTChart1.Series(0).YValues.get_Value(3).ToString());
  • 修改第9个位置的Y值为21:axTChart1.Series(0).YValues.set_Value(int.Parse(9,21);
  • 将第有个位置的坐标向X轴正向移动5个坐标:axTChart1.Series(0).XValues.set_Value(5,9);
  • 清除绘图:axTChart1.Series(0).Clear();
  • 清除刻度:axTChart1.Axis.Visible = false;
  • 清除底部刻度:axTChart1.Axis.Bottom.Visible = false;
  • Margin和左边相距 20% :axTChart1.Panel.MarginLeft = 20;
