yes it can possible private void checkBoxUseMultipleYAxis_CheckedChanged( object sender, System.EventArgs e) { if (checkBoxUseMultipleYAxis.Checked) { // Set custom chart area position Chart1.ChartAreas[ "Default" ].Position = new ElementPosition(25,10,68,85); Chart1.ChartAreas[ "Default" ].InnerPlotPosition = new ElementPosition(10,0,90,90); // Create extra Y axis for second and third series CreateYAxis(Chart1, Chart1.ChartAreas[ "Default" ], Chart1.Series[ "Series2" ], 13, 8); CreateYAxis(Chart1, Chart1.ChartAreas[ "Default" ], Chart1.Series[ "Series3" ], 22, 8); } else { // Set default chart areas Chart1.Series[ "Series2" ].ChartArea = "Default" ; Chart1.Series[ "Series3" ].ChartArea = "Default" ; // Remove newly created series and chart areas while (Chart1.Series.Count > 3) { Chart1.Series.RemoveAt(3); } while (Chart1.ChartAreas.Count > 1) { Chart1.ChartAreas.RemoveAt(1); } // Set default chart are position to Auto Chart1.ChartAreas[ "Default" ].Position.Auto = true ; Chart1.ChartAreas[ "Default" ].InnerPlotPosition.Auto = true ; } } public void CreateYAxis(Chart chart, ChartArea area, Series series, float axisOffset, float labelsSize) { // Create new chart area for original series ChartArea areaSeries = chart.ChartAreas.Add( "ChartArea_" + series.Name); areaSeries.BackColor = Color.Transparent; areaSeries.BorderColor = Color.Transparent; areaSeries.Position.FromRectangleF(area.Position.ToRectangleF()); areaSeries.InnerPlotPosition.FromRectangleF(area.InnerPlotPosition.ToRectangleF()); areaSeries.AxisX.MajorGrid.Enabled = false ; areaSeries.AxisX.MajorTickMark.Enabled = false ; areaSeries.AxisX.LabelStyle.Enabled = false ; areaSeries.AxisY.MajorGrid.Enabled = false ; areaSeries.AxisY.MajorTickMark.Enabled = false ; areaSeries.AxisY.LabelStyle.Enabled = false ; areaSeries.AxisY.IsStartedFromZero = area.AxisY.IsStartedFromZero; series.ChartArea = areaSeries.Name; // Create new chart area for axis ChartArea areaAxis = chart.ChartAreas.Add( "AxisY_" + series.ChartArea); areaAxis.BackColor = Color.Transparent; areaAxis.BorderColor = Color.Transparent; areaAxis.Position.FromRectangleF(chart.ChartAreas[series.ChartArea].Position.ToRectangleF()); areaAxis.InnerPlotPosition.FromRectangleF(chart.ChartAreas[series.ChartArea].InnerPlotPosition.ToRectangleF()); // Create a copy of specified series Series seriesCopy = chart.Series.Add(series.Name + "_Copy" ); seriesCopy.ChartType = series.ChartType; foreach (DataPoint point in series.Points) { seriesCopy.Points.AddXY(point.XValue, point.YValues[0]); } // Hide copied series seriesCopy.IsVisibleInLegend = false ; seriesCopy.Color = Color.Transparent; seriesCopy.BorderColor = Color.Transparent; seriesCopy.ChartArea = areaAxis.Name; // Disable drid lines & tickmarks areaAxis.AxisX.LineWidth = 0; areaAxis.AxisX.MajorGrid.Enabled = false ; areaAxis.AxisX.MajorTickMark.Enabled = false ; areaAxis.AxisX.LabelStyle.Enabled = false ; areaAxis.AxisY.MajorGrid.Enabled = false ; areaAxis.AxisY.IsStartedFromZero = area.AxisY.IsStartedFromZero; areaAxis.AxisY.LabelStyle.Font = area.AxisY.LabelStyle.Font; // Adjust area position areaAxis.Position.X -= axisOffset; areaAxis.InnerPlotPosition.X += labelsSize; }
