Using subchart

[Avijit]

Hi,
I want to use Teechart's SubChart's tool for achiving the below user interface.
Let me know if it is possible.

Query 1: Can a TeeChart tool bound to a SubChart tool. That means, i want to use Annotation tool inside a Subchart so that the annotation tool moves along with the subchart when the subchart is moved.

Please see the image below -

Hi Avijit,

Here you have an example to start with. Press control and drag the chart in the right.

Code: Select all

        public Form1()
        {
            InitializeComponent();
            CreateChart();
            CreateSubChart();
            InitializeChart();
            InitializeSubChart();
        }

        private Steema.TeeChart.TChart tChart1; //Chart1
        private Steema.TeeChart.TChart tChart2; //SubChart - Chart2
        private Steema.TeeChart.ChartController chartController1;
        private int MouseDownX, MouseDownY = -1;
        private void CreateChart()
        {
            tChart1 = new Steema.TeeChart.TChart();
            this.Controls.Add(tChart1);

            chartController1 = new Steema.TeeChart.ChartController();
            this.Controls.Add(chartController1);
            chartController1.Chart = tChart1;

            tChart1.Dock = DockStyle.Fill;

            tChart1.Chart.CustomChartRect = true;
            tChart1.Chart.ChartRect = new Rectangle(10, 10, 210, 210);
            tChart1.Panel.Gradient.Visible = false;
        }

        private void CreateSubChart()
        {
            Steema.TeeChart.Tools.SubChartTool subchart1 = new Steema.TeeChart.Tools.SubChartTool(tChart1.Chart);
            tChart2 = subchart1.Charts.AddChart("SubChart");
            tChart2.Panel.Gradient.Visible = false;

            Rectangle tmpRect = tChart1.Chart.ChartRect;
            tChart2.Width = tmpRect.Width;
            tChart2.Height = tmpRect.Height + 8;
            tChart2.Left = tmpRect.Left + tmpRect.Width + 10;
            tChart2.Top = 2;
            tChart2.Chart.ChartRect = new Rectangle(10, 10, 210, 210);

            tChart2.Zoom.Allow = false;

            tChart2.MouseDown += new MouseEventHandler(tChart2_MouseDown);
            tChart2.MouseMove += new MouseEventHandler(tChart2_MouseMove);
            tChart2.MouseUp += new MouseEventHandler(tChart2_MouseUp);
        }

        void tChart2_MouseUp(object sender, MouseEventArgs e)
        {
            MouseDownX = -1;
            MouseDownY = -1;
        }

        void tChart2_MouseMove(object sender, MouseEventArgs e)
        {
            if ((MouseDownX != -1) && (MouseDownY != -1))
            {
                tChart2.Left = tChart2.Left - (MouseDownX - e.X);
                tChart2.Top = tChart2.Top - (MouseDownY - e.Y);
                MouseDownX = e.X;
                MouseDownY = e.Y;
                Steema.TeeChart.Tools.Annotation annot1 = tChart2.Tools[0] as Steema.TeeChart.Tools.Annotation;
                annot1.Shape.Left = tChart2.Left + 20;
                annot1.Shape.Top = tChart2.Top + 50;
                tChart2.Refresh();
            }
        }

        void tChart2_MouseDown(object sender, MouseEventArgs e)
        {
            if ((Control.ModifierKeys & Keys.Control) == Keys.Control )
            {
                MouseDownX = e.X;
                MouseDownY = e.Y;
            }
        }

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;

            tChart1.Legend.Visible = false;
            new Steema.TeeChart.Styles.FastLine(tChart1.Chart);
            tChart1[0].FillSampleValues(5);
        }

        private void InitializeSubChart()
        {
            tChart2.Aspect.View3D = false;

            new Steema.TeeChart.Styles.FastLine(tChart2.Chart);
            tChart2[0].FillSampleValues(5);

            Steema.TeeChart.Tools.Annotation annot1 = new Steema.TeeChart.Tools.Annotation(tChart2.Chart);
            annot1.Text = "My annotation";
            annot1.Shape.CustomPosition = true;
            annot1.Shape.Left = tChart2.Left + 20;
            annot1.Shape.Top = tChart2.Top + 50;
            tChart2.Refresh();
        }
