Multi-Color plot using PlotStyle.Bar

[spongeb0b]

I am new to NinjaTrader and have made a simple SMA indicator using PlotStyle.Line that changes color based on it rising or falling. When using PlotStyle.Bar I can't get the color to change. How do you implement a multi-color bar?

Hello spongeb0b,

You can use PlotBrushes to color bar type plots. The sample from the help guide works for that type. This is also a simple way to demonstrate that just using the close price:

if (IsRising(Close))
    PlotBrushes[0][0] = Brushes.Blue;
else if (IsFalling(Close))
   PlotBrushes[0][0] = Brushes.Red;
else
   PlotBrushes[0][0] = Brushes.Yellow;

Jesse, thank you for your response. I realized after reading my question again that I wasn't very clear about what I was asking. If you think of a line plot as a single contiguous line then the example code you gave changes it's color back and forth. In other words that single line can take on 3 different colors. I want to do the same thing for a single bar when the style is PlotStyle.Bar. So for example a single bar could take on 3 different colors. I am using OnEachTick and setting values and switching colors intrabar. What I'm noticing is that when I set a value for the plot a.k.a. bar and switch colors it just re-paints the entire bar with the last color set. If I set the bar to 25 and color it red, then set the bar to 50 and color it green, and set it to 75 and color it yellow, I want the same bar to show all 3 colors at the values they were set.

Hello spongeb0b,

A single bar can only have one color, the plotbrushes changes the color for each of the plots datapoints in total.

Hi Jesse, I was afraid that was the case. Thank you so much for your help.
