Hi,
I'm trying to change the Value of the MiddleText of the speedometer to the
value that the tick of the speedometer points to.
I am changing the value of the tick of the speedometer via SetSpeedalue,
but when I try to change the middleText via SetMiddleText(), the tick mark
disappears, and no value is shown in the middle.

What can I do to solve this issue?
Attaching the code for your reference. (In the code, I have used an OnMouse
function for testing, but actually the value of Speedometer is changed via
some other data.)

Thanks
Regards,
Tanmay
