  Pointer is extended to the opposite side in Pointer Angular Meter

Hi,
I am using the Anugular Meter type chart with multiple pointers. In the Meter type charts,
the pointer is always extended to the opposite side (like in an analog clock needles).  I
checked the the sample chart available with the library, that too has the same behavior. I
am using the LinePointer type. There is option only to change the total length and width.
Is there anyway to trim the unwanted length at this one end ?

Thanks and regards,
Roopesh

Hi Roopesh,

You can use MeterPointer.setShape2 to use a custom shape as the pointer. A line is just a
thin rectangle, so it should be like (in C#):

private static readonly int[] lineShape = {-5, 0, 5, 0, 5, 1000, -5, 1000};
m.addPointer(myValue).setShape2(lineShape, myLengthRatio, myWidthRatio);

(In the default LinePointer is  {-5, -50, 5, -50, 5, 1000, -5, 1000}, in which the y-
coordinates of the bottom edge is at -50 instead of 0, that's why it goes through the origin
to the other side.)

Hope this can help.
