How get rid of the border in Tchart.

Hi, I want to get rid of the border in the tee chart.

I tried the below options, but they don't work either!

m_MyPlot.TChart.BorderBrush = System.Windows.Media.Brushes.Transparent;

m_MyPlot.TChart.BorderThickness = new Thickness(0);

I did try setting BorderBrush to Transparent and BorderThickness to 0 in design mode, but didn't work.

I have uploaded the image file (border.JPG) on your upload page.

Any advice?

Thanks in advance.

Hi Frances,

You need to set Panel.Bevel as shown here:

Code: Select all

		public Form1()
		{
			InitializeComponent();
			InitializeChart();
		}

		private void InitializeChart()
		{
			this.BackColor = Color.White;

			tChart1.Aspect.View3D = false;

			tChart1.Panel.Color = Color.White;
			tChart1.Panel.Gradient.Visible = false;
			tChart1.Panel.Bevel.Inner = Steema.TeeChart.Drawing.BevelStyles.None;
			tChart1.Panel.Bevel.Outer = Steema.TeeChart.Drawing.BevelStyles.None;

			tChart1.Walls.Back.Transparent = true;
		}

Thanks, It works now.
But, I have one more thing to ask that I have set the panel.color to transparent and looks ok in wpf ui, but when I export it as image, the whole background changes to black and I can't see anything.

Any advice on this?

Thanks in advance.

Hi Frances,

Thanks for reporting.

As you can see in TeeChart for .NET v3 release notes this was fixed for TF02013027. However, it seems to be broken again so I added the defect to the bug list (TF02013744) to be fixed for next releases. I also found that the only format that works is Metafile. It fails for PNG, BMP, JPG, TIFF and GIF.

Hi Frances,

After investigating the issue here we found that code below works fine for us here.

Code: Select all

		public Form1()
		{
			InitializeComponent();
			InitializeChart();
		}

		private void InitializeChart()
		{
			this.BackColor = Color.Red;
			tChart1.Panel.Transparent = true;
		}

		private void button1_Click(object sender, EventArgs e)
		{
			bool useBuffer = tChart1.Graphics3D.UseBuffer;
			tChart1.Graphics3D.UseBuffer = false;
			tChart1.Export.Image.PNG.Save(@"C:\temp\trans.png");
			tChart1.Graphics3D.UseBuffer = useBuffer;
		}

Could you please check if it works fine at your end?

Thanks in advance.
