问题描述
我想显示鼠标指针相对于当前jfree图表的坐标系的(x，y)位置.即使在图形的任何部分上都没有设置鼠标指针，我也希望不断地做到这一点.
I would like to display the (x, y) location of the mouse pointer with respect the coordinate system of the current jfree chart. I would like to do this constantly even if the mouse pointer is not set on any part of the graph.
我知道我可以按照此处所述的方式激活工具提示，但该工具提示会显示仅当鼠标位于图形点上方时，鼠标才会位于该位置.我怎么一直都能看到鼠标指针(工具提示之类的东西)旁边的XY?
I know I can activate the tooltip the way explained here but that displays the mouse location only if the mouse is on top of a graph point. How can I see the XYs all the time next to mouse pointer (tooltip or something)?
推荐答案
如此处所示，坐标位于由ChartMouseEvent中的getTrigger()返回的MouseEvent发送到ChartMouseListener.
As shown here, the coordinates are in the MouseEvent returned by getTrigger() in the ChartMouseEvent sent to a ChartMouseListener.
