Unifying metric on x-axis of a graph using series mode

Hi,

I am working with grafana 5.0.4 with MySQL as a data source and was trying to unify the value of x-axis. Currently, I am using two separate queries to have two values for the graph panel as seen in the image below


Is there a way to combine the x-axis having the same metric with values stacked up?

not sure what that means.

having same metric on the x-axis and multiple values against those metrics.

Not sure what you mean. Multi x value against some metric value? Where is x value coming from?
