Mouse wheel event

[dalshin]

Hi,

Is it possible to catch mouse wheel event? If I can, I would like to use this event for zooming in and out rather than scrolling up and down.

Hi dalshin,

If you can catch the MouseWheel event in your IDE, you can catch it for the TeeChart control. For example, in VS2008:

Code: Select all

        private void InitializeChart()
        {            
            axTChart1.Aspect.View3D = false;

            axTChart1.AddSeries(TeeChart.ESeriesClass.scFastLine);
            axTChart1.Series(0).FillSampleValues(25);

            this.MouseWheel += new MouseEventHandler(Form1_MouseWheel);            
        }

        void Form1_MouseWheel(object sender, MouseEventArgs e)
        {
            axTChart1.Header.Caption = "mousewheel event";
            Rectangle rect = new Rectangle(axTChart1.Location.X, axTChart1.Location.Y, axTChart1.ChartBounds.Right-axTChart1.ChartBounds.Left,axTChart1.ChartBounds.Bottom-axTChart1.ChartBounds.Top);
            if (rect.Contains(e.X, e.Y))
            {
                axTChart1.Header.Caption = axTChart1.Header.Caption + " in chart";
            }
        }
