如何从JfreeChart获取[x，y]值以设置鼠标在屏幕上的位置? [英] How to get [x,y] values from a JfreeChart to set the mouse position on screen?
本文介绍了如何从JfreeChart获取[x，y]值以设置鼠标在屏幕上的位置?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
此问题是从先前的问题[
但是我希望它看起来如下:
为了获得第二张图像的效果[在交叉点处有价格提示]，我需要模拟鼠标点动作，我知道如何使用机器人设置鼠标，但是我没有知道它的[x，y]值，所以我的问题是:如果我知道十字准线[x，y]，如何将它们转换为鼠标的[x，y]，所以当我将鼠标设置为那个位置，提示会显示出来吗?我试图在注释掉的代码[robot.mouseMove()]中实现这一点，但是它不起作用，正确的方法是什么?
解决方案
好的，感谢@trashgod，我想出了以下代码.
(1)它会在启动时显示信息，但是当用户移动鼠标后，它将消失并在新的鼠标位置显示信息:
plot.getRenderer().removeAnnotation(note); (2)它也足够聪明，可以避免出现左右边缘，因此注释不会在图表的左侧和右侧被剪掉.
note.setTextAnchor(Index< Volume_Color_Vector.size()/2?TextAnchor.TOP_LEFT:TextAnchor.TOP_RIGHT); 完整代码:

The app looks like this :
But I want it to look like the following :
In order to achieve the effect of the 2nd image [ with hint of the Price at the crossing point ], I need to simulate a mouse point action, I know how to set the mouse using a Robot, but I don't know the [x,y] values for that, so my question is : if I know the cross-hair [x,y], how to convert them to the [x,y] for the mouse so when I set the mouse to that position, the hint will show up ? I was trying to achieve that in the commented out code [ robot.mouseMove() ], but it didn't work, what's the right way to do that ?
解决方案
Alright, thanks to @trashgod, I came up with the following code.
(1) It would show info at start up, but after user moves mouse, it will disappear and show info at new mouse location:
plot.getRenderer().removeAnnotation(note);
(2) It's also smart enough to avoid left and right edge, so annotation won't be cut off at the left and right side of the chart.
note.setTextAnchor(Index<Volume_Color_Vector.size()/2
?TextAnchor.TOP_LEFT:TextAnchor.TOP_RIGHT);
Complete code:
