Visualize data from multiple influxdbs in one graph

I am trying to show data from multiple influxdbs in a single graph to compare. I tried to use Chronograf and Grafana, but failed. Could some one help me in this issue.

My idea is to monitor changes in current data by comparing baseline data or data stored in diff data base.

@sai This is not currently supported in either Grafana or Chronograf. You can display graphs from different datasources on the same dashboard in Grafana and that is a feature we are planning to add in chronograf soon as well.
