在JFreeChart的条形图上的X轴标签旁边添加图像 [英] Add an Image next to a X-axis label on a JFreeChart's barchart

问题描述

我需要使用JFreeChart库创建的条形图。

I have requirement for the barchart which I have created using JFreeChart libraries.

我用一个例子说明了这一点。让我们说：
我在X轴（学生）上绘制了John，Mark，Louis和Keith，并在Y轴上绘制了各自的标记。我为每个学生使用三个不同的酒吧来展示他们各自的英语，科学和数学标记。

I am illustrating this using an example. Lets say: I have plotted "John", "Mark", "Louis" and "Keith" on the X-axis (Students) and their respective marks on the Y-axis. I am using three different bars for each of the students to show their respective English, Science, and Maths marks.

让我们说，科学的权重最大，因此获得科学最高奖的学生将获得金奖。 数学中最高的会给学生一个白银，而英语最高的会给他一个铜奖

Lets say, Science weigh the most, hence a student getting highest in Science would get a "Gold-Medal". Highest in "Maths" would fetch a student a "Silver", and highest in English would fetch him a "Bronze"

我想放一个小图像（黄金，在每个科目中获得最高分的学生的标签旁边的银色或青铜色。一个特定的学生（显然）可以获得所有奖牌。可以这样做（或类似的事情）。

I want to put a small image (gold, silve or bronze) beside the label of the student who has got the highest marks in each of the subjects. A particular student (obviously) can get all the medals. Can this (or a thing similar to this) be done.

我正在使用JFreeChart的ChartFactory.createBarChart（...）api。我能够正确绘制图形，但坚持上述要求。

I am using JFreeChart's ChartFactory.createBarChart(...) api for this. I am able to plot the graph correctly but stuck with the above requirement.

谢谢！
