Thanks .I know how to use tooltip, tooltip shows  just when you put the mouse over the point,Now  whant I want is no matter I put the mouse over the point or not,the message(xvalue,yvalue or some information)  will always show arround the mouse!

Hello,

I believe that the functionality you need is the one described in this blog post. I have modified slightly the project. You can review the attached file.

Basically I changed the LayoutRoot from Grid to Canvas (so I can position freely objects inside of it) and on MouseMove set the Canvas.Top and Canvos.Left attached properties of the infoText to the coordinates given by the MouseEventArgs.GetPosition(). Also the 2 TextBlock-s (that display the coordinates of the mouse pointer) are hidden and shown on MouseLeave and MouseEnter respectively.

I hope this is the solution you are looking for.

I want the result is here:https://www.yousendit.com/download/TEhVZHlnUzg1UjZjZDhUQw, the result is better than tooltip,because When I drap or click the chartarea,I still want to show the (xvalue,yvalue).But tooltip is not display when I click or drag the area,and Location Crosshair is always show but is far away around the mouse!!
