3 仪表盘上设置
3.1 时间控制 ：
生成仪表盘以后，展示的数据是添加的趋势图所定义的数据范围（即当时搜索的日志来源、时间范围）。当我们的时间范围发生变化，每天都有新的数据导入的话，能否像数据搜索时一样，对仪表盘获取数据的时间范围进行设置呢？日志易提供了两种时间范围设置方法。
1、可以通过日志易自带的过滤按钮来控制标签页内所有图表的时间范围，做统一处理。
如当我们指定时间范围为“10 分钟”时，该仪表盘标签页内的所有图表的时间范围都为最近 10 分钟，图表会从最近 10 分钟采集的日志中依照定义好的过滤及处理规则获取数据并展示。
2、也可以单独指定某个图表的查询时间范围，图表框内附带的工具栏提供针对该图表时间控制功能。当我们想要该图表实时刷新时，如每 1 分钟刷新一次，可以选择“实时 1 分钟”，如下图:
3.2 图表配置 ：
生成仪表盘之后，我们是否还能对仪表盘的各种配置项及参数进行修改呢？答案是肯定的。
仪表盘中各图表自带的设置按钮，有一个设置项“通用配置”，可以通过它修改这些配置信息以调整图表的数据来源及其他设置。
打开“通用配置”可以看到，通过前期操作生成的趋势图已经由系统自动处理生成了一个查询语句。可以修改这个查询语句从而调整图表的显示效果，如何修改这个语句以实现更多样化的图表展示呢，可以参考我们前面发布的《花几分钟看完这篇使用指南，再也不用担心用不好SPL了》。
3.3 仪表盘其他配置 ：
仪表盘右上方的菜单栏除了过滤按钮外，还有一些其他按钮。
1、仪表盘默认显示为“白天模式”，我们可以通过下面的按钮将其调整为“夜间模式”。
2, in addition, the dashboard can display full-screen, stored as a report, regularly updated, removed or added provided charts.
