  The graph and values was difference with zabbix graph.
  I found some description in official website like this:
  https://www.zabbix.com/documentation/3.2/manual/config/visualisation/graphs/simple
  > Recent data vs longer periods
  > For very recent data a single line is drawn connecting each received value. The single line is drawn as long as there is at least one horizontal pixel available for one value.
  > For data that show a longer period three lines are drawn - a dark green one shows the average, while a light pink and a light green line shows the maximum and minimum values at that point in time. The space between the highs and the lows is filled with yellow background.

Just look at this example:

Can we do that min/max automatically when we are collecting from trends, and not when we are using history?

That would help a lot when debugging and creating/managing dashboards.

@fpaternot I'm not sure, may be it requires some tricks. Flow of this looks like:

1. Add two additional series (with min and max values)
2. Create series override rule for panel
