- line/point charts based on XY coordinates
- category (bar) charts
- OHLC financial charts
- pie charts
- bubble chars
- Gantt charts

I use it and love it. One thing is really missing, in my point of view : manage mouse event to have information about x/y values of mouse position.
May be it's possible to extend this facility by the user himself (but I don't know how).

Yes, it's possible. But it need additional code.
First you need to translate mouse position to chart data coordinate space, by calling AxisPlot::ToData.

Ya,this function is good idea.
I use it for candlesticks chart, but as you think.
Miss:manage mouse event to hit bar of chart and to show something

Log - mean logarithmic? Logarithmic axis is in future plans. :)
Today only linear axis supported.
