plot and zoom

Hello guys,
i'm new here and i made the first tests with zorro. Now i have 2 questions:
1.) If i want to plot a curve i can use "plot()". Then i can analyse the curve with zoom and check every single candle.
But if i want to plot symbols above or below the candles i have to use "plotGraph()". Unfortunately the function zoom doesn't work with "plotGraph()".The scale doesn't change.
What can i do to analyse the single candles?
2.) If i use another indicator in addition and want to plot it in another window, the marks from the first window (from above and below the candles) come to the second window.
Where is the mistake?

Thank you for the help

If you mean plotting larger or smaller symbols: use PlotScale for that. Zooming zooms the chart, it won't make text or symbols bigger.

If you have plot objects in a wrong window, you likely called the plot commands in wrong order.
