Dual-Axis support? What about fsync mode context? #1

Hey @nubskr,

I was thinking it'd be great to have Dual-Axis support for Walrus. For example maybe putting something under

That looks something similar to this:

def create_dual_axis_plot(self):
    self.fig, self.ax1 = plt.subplots(1, 1, figsize=(12, 6))
    self.ax2 = self.ax1.twinx()
    
    self.ax1.set_ylabel('Writes/sec', color='b')
    self.ax1.tick_params(axis='y', labelcolor='b')
    
    self.ax2.set_ylabel('MB/sec', color='r')
    self.ax2.tick_params(axis='y', labelcolor='r')

I also realized whilst using Walrus, I didn't see any fsync mode context. So essentially the benchmarks can run with different fsync settings, but the visualization doesn't show which mode was used, any plan when updates/versions are pushed out this may be a feature?

Thanks for Walrus @nubskr, been super helpful to me for this project I'm working on.
