Override y-scale and x-scale using xlim/ylim or xrange/yrange in quantmod::chart_Series() - impossible?
I am trying to plot some support/resistance lines on top of quantmod::chart_Series(). The issue is that the interesting support/resistance lines are outside (below or above) series data range up to current time (I would also like to extend a chart a bit to the right beyond last timestamp of data).

Looking at the source code of quantmod::chart_Series() I can see no way of specifying ylim/xlim or, what was possible in "the old days" with quantmod::chartSeries using yrange to override y-scale. Comment here https://r-forge.r-project.org/scm/viewvc.php?view=rev&root=quantmod&revision=520 is also comfirming my hunch...

Is my diagnosis correct or is there maybe a way that enables y-scale overriding in quantmod::chart_Series? Any idea how to do what I want highly appreciated.

Thanks.

Best,
Samo
