c# - XamDataChart 具有未知数量的系列 - 轴标题

Question

我正在使用 Infragistics xamDataChart，并绘制未知数量的系列。我正在使用此处发布的解决方案，并且运行良好：XamDataChart with unknown number of series

我的问题是关于如何在 XAML 中编辑生成的轴标题。我希望只生成一组 x 和 y 轴，因为我将构建我的数据，这样就足够了。

我该怎么做？

谢谢！

所以如果我做对了，你想编辑轴的名称吗？也许为时已晚，但这对我有帮助。

您可以在方法中设置轴的任何属性UpdateSeriesProperties。例如，这就是我的方法的样子：

private void UpdateSeriesProperties(Series series, SeriesType type, object seriesSource, bool shouldRenewAxes, bool clearOnly)
    {
        if (series != null)
        {
            switch (type)
            {
                case SeriesType.LineSeries:
                    try
                    {
                        HorizontalAnchoredCategorySeries category = series as HorizontalAnchoredCategorySeries;
                        category.ClearValue(HorizontalAnchoredCategorySeries.ValueMemberPathProperty);
                        category.ClearValue(HorizontalAnchoredCategorySeries.ItemsSourceProperty);

                        if (!clearOnly)
                        {
                            category.SetBinding(HorizontalAnchoredCategorySeries.ValueMemberPathProperty,
                                new Binding(YMemberPath) { Source = seriesSource });

                            category.SetBinding(HorizontalAnchoredCategorySeries.ItemsSourceProperty,
                                new Binding(ItemsSourcePath) { Source = seriesSource });
                        }

                        if (shouldRenewAxes)
                        {
                            if (category.XAxis != null)
                                _owner.Axes.Remove(category.XAxis);

                            if (category.YAxis != null)
                                _owner.Axes.Remove(category.YAxis);

                            if (!clearOnly)
                            {
                                CategoryDateTimeXAxis xAxis = new CategoryDateTimeXAxis();
                                xAxis.LabelSettings = new AxisLabelSettings();
                                xAxis.SetBinding(CategoryDateTimeXAxis.ItemsSourceProperty,
                                    new Binding(ItemsSourcePath) { Source = seriesSource });
                                xAxis.SetBinding(CategoryDateTimeXAxis.DateTimeMemberPathProperty,
                                    new Binding(XMemberPath) { Source = seriesSource });
                                xAxis.Label = "{" + seriesSource.GetType().GetProperty(XMemberPath).GetValue(seriesSource, null) + "}";

                                xAxis.StrokeThickness = 8;
                                xAxis.LabelSettings.Extent = 20;
                                xAxis.LabelSettings.Location = AxisLabelsLocation.OutsideBottom;
                                xAxis.LabelSettings.VerticalAlignment = System.Windows.VerticalAlignment.Center;

                                NumericYAxis yAxis = new NumericYAxis();
                                yAxis.LabelSettings = new AxisLabelSettings();
                                yAxis.StrokeThickness = 2;
                                yAxis.LabelSettings.Extent = 40;
                                yAxis.LabelSettings.Location = AxisLabelsLocation.OutsideLeft;

                                yAxis.MinimumValue = Convert.ToDouble(seriesSource
                                                                        .GetType()
                                                                        .GetProperty("MinMax")
                                                                        .GetValue(seriesSource, null)
                                                                        .ToString()
                                                                        .Split(';')[0]);
                                yAxis.MaximumValue = Convert.ToDouble(seriesSource
                                                                        .GetType()
                                                                        .GetProperty("MinMax")
                                                                        .GetValue(seriesSource, null)
                                                                        .ToString()
                                                                        .Split(';')[1]);

                                if (_owner.Axes.Count == 0)
                                {
                                    yAxis.LabelSettings.Visibility = System.Windows.Visibility.Visible;
                                    _owner.Axes.Add(xAxis);
                                    _owner.Axes.Add(yAxis);

                                    category.XAxis = xAxis;
                                    category.YAxis = yAxis;
                                }
                                else
                                {
                                    yAxis.LabelSettings.Visibility = System.Windows.Visibility.Hidden;
                                    _owner.Axes.Add(yAxis);

                                    category.XAxis = (Infragistics.Controls.Charts.CategoryAxisBase)_owner.Axes[0];
                                    category.YAxis = yAxis;
                                }
                            }
                        }
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK, MessageBoxImage.Error);
                    }
                    break;
                default:
                    break;
            }
        }
    }

如您所见，我在这里设置最小/最大值、标签、绑定等。

您还可以设置 Graph 的系列的属性：您可以像这样添加Name属性：SeriesViewModel

private string name;            
public string Name          
{           
    get { return name; }            
    set { name = value; OnPropertyChagned("Name"); }            
} 

SeriesBinderInfo然后您可以在方法中访问此属性CreateSeries：

series.Title = seriesSource.GetType().GetProperty("Name").GetValue(seriesSource, null);

您可以在其中设置任何属性以series在图表中反映该属性。
