Thanks Ben for replying. I did see that function in Windows.PlotSurface2D. However, how would I know if I am mousing over a chart series or not? In other words the mouse over will be different if I am hovering over a candlestick vs if I am in empty space in the chart (i.e. not hovering over a series) Any ideas? ----- Original Message ---- From: Ben Gruver <jes...@je...> To: npl...@li...

I am trying to create my own "hit test" but I cant figure out how figure out what the coordinates are of each individual data point in the series. Any ideas where that info is stored? majid ----- Original Message ---- From: Ben Gruver <jes...@je...> To: npl...@li... Sent: Tuesday, July 1, 2008 3:30:42 PM Subject: Re: [Nplot-devel] mouseover text on plot Ah, ok. I see your difficulty. I don't recall seeing any built-in way to determine if the cursor is over a data point. (Although that doesn't mean it's not there :)). Assuming it's not, you'll probably have to do your own "hit test" to determine this. There are various functions which allow you to translate between world and physical coordinates, which you may find helpful. I'm kinda surprised it doesn't have support for that.. I may just not have run across that functionality yet :) On Tue, Jul 1, 2008 at 3:00 PM, MT <mt...@ya...> wrote: > Thanks Ben for replying.

Take a look at PhysicalAxis.WorldToPhysical. This will tranlate a world (data) coordinate to the corresponding physical (screen) coordinate. You can access the PhysicalAxis objects that were used for the most recent Draw operation via PlotSurface2D.PhysicalXAxis1Cache (along with the other 3 axises). To get a list of the data points themselves, I believe you can use CandleDataAdapter.
