A股交易时间为9:30-11:30,13:00-15:00，11:31-12:59分之间是没有数据的，X轴时间刻度也只显示9:30、10:30、11:30、14:00、15:00这5个刻度值。
要实现这个时间显示效果有两种方式：
1、直接使用ChartFactory.createTimeSeriesChart()实现，由于默认下显示的时间是连续的，11:31-12:59没有数值，会显示成一条直线，为了实现数据的连续，需要把13:00-15:00换算成11:31-13:30的数值，实现代码：

2、直接使用自带的折线图，但是默认的X轴坐标值不能只显示9:30、10:30、11:30、14:00、15:00这5个刻度值，需要重写CategoryPlot.drawDomainGridlines、CategoryAxis.refreshTicks、CategoryAxis.drawCategoryLabels三个方法，实现代码如下：
