Hi Jagan,
Do you mean something like the attached image?
The image is produced by adding two pointers to the meter (calling BaseMeter.addPointer twice). For the second pointer, I use MeterPointer.setShape to set an inverted pentagon as the pointer shape. See:
https://www.advsofteng.com/doc/cdnet.htm#MeterPointer.setShape2.htm
In C#, it is likeL
// First pointer
m.addPointer(74.25, 0x0000cc);
// Second poineter
MeterPointer p = m.addPointer(15, 0xcc0000);
// The original "pencil pointer" shape as described in the ChartDirector documentation
int[] pointerShape = { -30, 0, 30, 0, 30, 768, 0, 1000, -30, 768 };
// Invert, shorten, and shift the pointer upwards
for (int i = 1; i < pointerShape.Length; i += 2)
pointerShape[i] = 1300 - pointerShape[i] * 8 / 10;
p.setShape2(pointerShape);
Hope this can help.
Regards
Peter Kwan

Create 2 set of pointers (up and down) in horizontal Linear Meter
