What is maximum? If it's the biggest point in ranges, it can be derived from ranges and doesn't need to be passed separately

You are right. I will add logic to get the maximum value(Basically the largest end value in the array)

| * line(x-axis) by incrementing the start point by 1 and decrementing end point by -1 on the | ||

I created a feature branch and sent another pull request using that, and will reset my master branch to upstream |
