jfree折线图显示每个索引的值

Question

I am trying to create a using jfree chart library line chart and i need to display the value associated with each index in the lineChart, I cannot use a tool tip for this because I am converting the chart into an image, is there a way of displaying the value on top of each index?

Thanks, Bhavya
