1) Allow NinjaScript access to the chart's background color
An increasing number of users are recognizing the advantages of using black chart backgrounds. With access to the chart background color the appropriate color for text and drawn objects can be used in indicators and strategies.
2) Allow NinjaScript to access and modify the chart's right side margin value.
Now that lines can be drawn to the right of the zero bar, indicators need to know if the chart's right side margin is wide enough to hold the drawn lines so that chart bars are not obscured and increase the margin if necessary.
