plot(binary(), map(), [plot_opt()]) :: :ok

Plot the metric name to the screen

If there are tags for the metric you can pass those in the second argument:

Mobius.Charts.plot("vm.memory.total", %{some: :tag})

By default the plot will display the last 3 minutes of metric history.

However, you can pass the :from and :to options to look at a specific range of time.

Mobius.plot("vm.memory.total", %{}, from: 1630619212, to: 1630619219)

You can also plot data over the last x amount of time. Where x is an integer. When there is no time_unit() provided the unit is assumed to be :second.

Plotting data over the last 30 seconds:

Mobius.plot("vm.memory.total", %{}, last: 30)

Plotting data over the last 2 hours:

Mobius.plot("vm.memory.total", %{}, last: {2, :hour})
