Content of the graph shifts when scaling in and out

Hi Ivan,

Thanks for the link, however, it is still not clear to me whether I need to manually adjust the scroll value when scaling in order to prevent the contents of the chart from shifting right or left (and if so how do I do this), or if there is a setting that will handle this automatically.

This is how we generate the chart (to keep it simple I am showing only one XYSeries):

private Infragistics.Win.UltraWinChart.UltraChart chart_smile;

this.chart_smile = new Infragistics.Win.UltraWinChart.UltraChart();

this.chart_smile.ChartType = Infragistics.UltraChart.Shared.Styles.ChartType.Composite;

this.chart_smile.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;

this.chart_smile.Name = "chart_smile";

this.Controls.Add(this.chart_smile);

ChartArea myChartArea = new ChartArea();

AxisItem axisX1 = new AxisItem();

axisX1.OrientationType = AxisNumber.X_Axis;

axisX1.DataType = AxisDataType.Numeric;

axisX1.Visible = true;

axisX1.Labels.ItemFormatString = "<DATA_VALUE:0.##>";

axisX1.Labels.Orientation = TextOrientation.VerticalLeftFacing;

axisX1.SetLabelAxisType = SetLabelAxisType.ContinuousData;

axisX1.Margin.Near.MarginType = LocationType.Percentage;

axisX1.Margin.Near.Value = 0;

axisX1.Margin.Far.MarginType = LocationType.Percentage;

axisX1.Margin.Far.Value = 0;

axisX1.Extent = 30;

AxisItem axisY1 = new AxisItem();

axisY1.OrientationType = AxisNumber.Y_Axis;

axisY1.Labels.ItemFormatString = "<DATA_VALUE:0.##>";

axisY1.Visible = true;

axisY1.SetLabelAxisType = SetLabelAxisType.ContinuousData;

axisY1.Margin.Near.MarginType = LocationType.Percentage;

axisY1.Margin.Near.Value = 0;

axisY1.Margin.Far.MarginType = LocationType.Percentage;

axisY1.Margin.Far.Value = 0;

axisY1.Extent = 30;

myChartArea.Axes.Add(axisX1);

myChartArea.Axes.Add(axisY1);

this.Chart_smile.CompositeChart.ChartAreas.Add(myChartArea);

CompositeLegend scatterLegend = new CompositeLegend();

scatterLegend.Bounds = new Rectangle(85, 0, 25, 40);

scatterLegend.BoundsMeasureType = MeasureType.Percentage;

scatterLegend.PE.ElementType = PaintElementType.Gradient;

scatterLegend.PE.FillGradientStyle = GradientStyle.ForwardDiagonal;

scatterLegend.PE.Fill = Color.Transparent;

scatterLegend.PE.FillStopColor = Color.Transparent;

scatterLegend.Border.CornerRadius = 0;

scatterLegend.Border.Thickness = 0;

ChartLayerAppearance chartLayerAppearance = new ChartLayerAppearance();

chartLayerAppearance.ChartType = ChartType.ScatterChart;

chartLayerAppearance.ChartArea = myChartArea;

chartLayerAppearance.AxisX = axisX1;

chartLayerAppearance.AxisY = axisY1;

chartLayerAppearance.Key = "Fitted";

ScatterChartAppearance sca = ((ScatterChartAppearance)chartLayerAppearance.ChartTypeAppearance);

sca.LineAppearance.Thickness = 1;

sca.ConnectWithLines = true;

sca.Icon = SymbolIcon.Circle;

sca.IconSize = SymbolIconSize.Small;

XYSeries dataSeries = dataSeriesCollection[i];

dataSeries.PEs.Add(new PaintElement(Color.Red));

dataSeries.Label = "Fitted";

dataSeries.Key = "Fitted";

dataSeries.Visible = true;

chartLayerAppearance.Series.Add(dataSeries);

scatterLegend.ChartLayers.Add(chartLayerAppearance);

this.chart_smile.CompositeChart.ChartLayers.Add(chartLayerAppearance);

this.chart_smile.CompositeChart.Legends.Add(scatterLegend);

this.chart_smile.CompositeChart.ChartAreas[0].Axes[0].ScrollScale.Visible = true;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[0].Extent = 50;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[0].ScrollScale.Scale = xaxisScaleValue;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[0].TickmarkPercentage = xaxisTickPercentage;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[1].ScrollScale.Visible = true;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[1].Extent = 50;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[1].ScrollScale.Scale = yaxisScaleValue;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[1].TickmarkPercentage = yaxisTickPercentage;

this.chart_smile.CompositeChart.ChartAreas[0].Axes[1].ScrollScale.Height = 3;

this.chart_smile.DataBind();

this.chart_smile.Refresh();
