custom Plot() method AutoScale and PriceMarkers

[shawnj]

I know NT does not offer format support for overriding Plot() but perhaps someone can supply some "unofficial" info.

Do we have a way to Scale or AutoScale the screen from the Plot method? I'm thinking for now I'll have to add two "dummy" Plots in the OnBarUpdate() and position a couple of "invisible" dots on the screen to force AutoScale. This seems a little crude, so I thought I'd see if there is a better way to aproach this.

And while I'm asking "unofficially", with overriding Plot() do we have any way of showing the PriceMarker.

thanks,
