thank you so much!
I still have a question!
As support, we must write code by script (java) to find mouse position then display image... ==> Write fix display image for one chart.
So, Can we write one function by vb.net to do it??
We want to display image static for chart dynamic
>> Example: If I choose Male, it will display one chart, and we choose all (male and female), this form display two chart.
And, with one chart will have the property display other image when move the mouse....
=======================================
function mousemove(e) { e = e || window.event; var divTag = $('<%=MyDiv.ClientID %>'); if (topPosition == 0) { var chartTag = $('<%=Chart1.ClientID %>'); // I want this chart is dynamic leftPosition = getXLocationFromBody(chartTag) + (chartTag.clientWidth / 2); topPosition = getYLocationFromBody(chartTag) + (chartTag.clientHeight / 2); } var mouseXPosition = getMousePosX(e); var mouseYPosition = getMousePosY(e); var mouseX if (mouseXPosition > leftPosition) mouseX = mouseXPosition - 10; else mouseX = mouseXPosition + 10; var mouseY if (mouseYPosition > topPosition) mouseY = mouseYPosition - 10; else mouseY = mouseYPosition + 10; divTag.style.left = mouseX + "px"; divTag.style.top = mouseY + "px"; divTag.style.position = "absolute"; }
