Points

[TomAgos]

Hey

im using the 'Point' series on top of 'FastLine' to show the points in the line.

my question is:
can i make the shape of the Pointer of Points to not fill the inner shape with the color?

this is my code to create instance of Points:

Code: Select all

       public static Points CreatePointsLine(DataRecVectorM vectorM, Chart chart)
       {
           return new Points(chart)
           {
               Color   	= ChartDataToZData.MColorToDColor(vectorM.Color),
               Pointer 	=
               {
                   Style       	= vectorM.SelectedSymbolStyle,
                   HorizSize   	= 5,
                   VertSize    	= 5,
               },
           };
       }

For example, if the defined color is red and the shape (Pointer.Style) is triangle, i want to draw a red triangle but transparent on the inside.

Hello TomAgos,

There are a few ways to achieve this. If you're using a WinForms App, you can use the design-time editor to help you explore all the possibilities with ease. However, here’s how you can do it through code.

Given a Point series like this
Points points = new Points();
You can set a red border with a transparent inside using the following line:

points.Pointer.Pen.Color = System.Drawing.Color.FromArgb(255, 0, 0); // Red

To change the pointer shape to a triangle, use:

points.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Triangle;


Another way to make the inside transparent is by setting the same color for both Points.Color and _TChart.Panel.Color

For example, if you haven’t changed the chart's panel color (which is usually white), you can use:
points.Color = Color.FromArgb(255, 255, 255); // White

I hope these tips were helpful! Let me know if they worked for you, or if we should explore a different approach. If there’s anything else I can assist you with, feel free to ask.

Best regards,
Edu
