plotter: add support for figure title
Created by: derkling
The LinePlotter can generate one or many plots, depending on pivoting and filters configuration. All these plots usually provides a common view on a specific set of metrics and/or experiment. An overall figure title could be useful to better represent what the set of generated plots refers to.
This patch adds the required support to defined a figure title which can be defined using an optional new 'title' paramter. For example:
trappy.LinePlot(run, pivot="cpu", title="This is a title").show()
