    resource-graph: Adaptive ymax
    
    For the case of data being I/O bytes written/read, we can't just assume a
    particular fixed value for max on y-axis (ymax) since I/O speed varies a
    lot across different hardware. The result of a fixed ymax is typically
    graphs fluctuating between 0 and ymax and that is not just useless but
    also looks ugly.
    
    Lets reset ymax to the value of data point if it happens to be greater
    than current ymax.
