Changing the metrics selector from a metric with multiple oplets to a few counters resulted in a bad y-axis legend

When a quarks application has metrics and multiple oplets have a counter say, the x-axis tick marks can become illegible. Although eventually when the refresh interval is called again, the tick marks are removed, the tick marks look bad until this refresh occurs.
I'll fix it so the tick marks only appear after a refresh for metrics whose tick marks will fit in the space provided.
