Hi, all:
I'm writing to ask how to use QWT to draw a curve with multiple colors???
Say, I've got a 2D curve, say, y = f(x), both x and y are natural number.
x is the time index, it starts from 1 and till 1000 ( milliseconds)
and y is a number calculated with the time goes by. it varies from 1 to 20 .
I want to realize something like:
x from 1 to 100, draw red dots
x from 101 to 500, draw yellow dots
x from 501 to 990, draw red dots again
x from 991 to 1000, draw blue dots.
So, how can I realize that?
Best Regards
JIA
