XamDataChart with unknown number of series - Axis Titles

Question

I am working with the Infragistics xamDataChart, and plotting an unknown number of series. I am using the solution posted here, and it is working well: XamDataChart with unknown number of series

My question is on how to edit the Axis Titles generated, in XAML. I would like for there to only be generated one set of x and y axes, as I will structure my data so that these will be sufficient.

How do I go about this?

Thanks!

So if I am getting it right, you want to edit the name of axis? Maybe too late, but this helped me.

You can set any property of axis in method UpdateSeriesProperties. So for example this is how my method looks like:

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;
            }
        }
    }

As you can see I am setting min/max values, labels, binding etc. here.

You can also set properties of Graph's Series: You can add Name property in your SeriesViewModel like this:

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

Then you can access this property in SeriesBinderInfo in method CreateSeries:

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

You can set any property of series in there to reflect that in your graph.
