LinePlotterIndicator - how to change color, line width etc.?

deedy

I have a custom indicator with several lines. One of the line I would like to plot in a separate subplot.

I can do it using the SMA trick where I create a new instance of an SMA indicator then pass in my line.

I can also use the LinePlotterIndicator method.

My question is - how can I change line colour / plot type etc.?

Many thanks

I've already checked that

If you have checked that, what's missing? Unless you are a bit more specific ... adding some code with your own attempt at something does usually help.

So I have this in my strategy:

my_indicator = bt.LinePlotterIndicator(self.indicator.my_indicator_line, "ABC")

...and I don't know where to interface with this thing to tell it I want a green histogram

A LinePlotterIndicator is only meant to be an aid for quickly plotting a line. If you really want to customize it, you should go for a custom indicator in which you can define all properties of a line using plotlines

class MyCustomIndicator(bt.Indicator):
    lines = ('abc',)
    plotlines = dict(abc=dict(ls='--'))

As indicated in Docs - Plotting - Section: Line specific plotting options, customizations like line colors or line style (like in the above example) are from matplotlib and you have to refer to its documentation.
