标题不支持设置中文字体

[nanakoww]

我安装了中文字体，但是标题部分没有生效，如图

测试代码如下：

x := "18:44:10 18:44:15 18:44:20 18:44:25 18:44:30 18:44:35 18:44:40 18:44:45 18:44:50 18:44:55 18:45:00 18:45:05 18:45:10 18:45:15 18:45:20 18:45:25 18:45:30 18:45:35 18:45:40 18:45:45 18:45:50 18:45:55 18:46:00 18:46:05 18:46:10 18:46:15 18:46:20 18:46:25 18:46:30 18:46:35 18:46:40 18:46:45 18:46:50 18:46:55 18:47:00 18:47:05 18:47:10 18:47:15 18:47:20 18:47:25 18:47:30 18:47:35 18:47:40 18:47:45 18:47:50 18:47:55 18:48:00 18:48:05 18:48:10 18:48:15 18:48:20 18:48:25 18:48:30 18:48:35 18:48:40 18:48:45 18:48:50 18:48:55 18:49:00 18:49:05 18:49:10 18:49:15 18:49:20"

	valueX := strings.Split(x, " ")

	valueY := [][]float64{}
	valueY = append(valueY, [][]float64{
