<p>smartchart提供非常精细的数据刷新功能,及内存加速功能
你可以在数据集开发界面的菜单中，连接图标&ndash;&gt;刷新设定，进行设定

<p>你可以设定前端页面数据集向后端请求刷新的时间间隔，单位秒</p>
<blockquote>
<p>如果你发现定时刷新，数据并没有变化，可能原因是您数据的缓存时间设定大于定时刷新的时间</p>

<p>smartchart专业版提供内存加速技术，对数据库仅需请求一次，之后都是毫秒级响应</p>
<ul>
<li>间隔时间刷新,单位分钟,如设定间隔时间为0.5, 则如果下一次访问时间超过30秒, 即触发数据刷新</li>
<li>固定时点刷新, 如设定间隔时间为-1, 则固定时点刷新, 即访问的时间超过固定的时点时(如上图每天12:39), 触发数据刷新</li>
<li>强制刷新, 访问url加上&amp;refresh=Y, 则强制刷新数据, 此刷新不会影响间隔或固定刷新的时间, 不会更新下次同步时间</li>
