Add Diagram Controls on Chart

[Ani]

Hi,

I need to add Diagram controls on the Chart Area above the plotted chart values. The diagram control needs to be fixed at that point. Is this possible?

Hi Ani, 

Thanks for using Syncfusion products. 

We have prepared a simple sample for your requirement and it can be downloaded from the following link 

DiagramInChart 

Query #1: I need to add Diagram controls on the chart area above the plotted chart values 

We can add Diagram controls as child controls to chart and place them at desired location. 

Please refer the following code snippet to add Diagram control on Chart 

[C#] 

 

            //Add diagram as a child control to Chart 

            this.chartControl1.Controls.Add(this.diagram1); 

 

            //Ensure size of the diagram control will not change after resizing 

            this.diagram1.Dock = DockStyle.None; 

            this.diagram1.Anchor = AnchorStyles.None; 

Query #2: The diagram control needs to be fixed at that point 

We can use the Paint event of Chart control and GetPointByValue method of ChartArea to place the diagram at fixed location. 

Please refer the following code snippet to achieve this 

[C#] 

 

            //Place diagram contol at fixed location using Paint event 

            this.chartControl1.Paint += chartControl1_Paint; 

 

        //Paint event of Chart 

        void chartControl1_Paint(object sender, PaintEventArgs e) 

        { 

            ChartControl chart = sender as ChartControl; 

            //Place diagram at a fixed location (eg: [4, 80]) 

            this.diagram1.Location = chart.ChartArea.GetPointByValue(new ChartPoint(4, 80)); 

        } 

Please let us know if you have any concern.
