    to match the docs this possibly wants a || autoRange
    
    otherwise it is having an effect; just not a very useful one.

    we should call normalizeData here too?
    
    otherwise it won't have an effect until the next addSample()

    does it makes sense to 
    
    if (autoRange)
    {
      if (m_rangeMax != adjustedMax) {
        m_rangeMax = adjustedMax
        emit autoMaxChanged()
      }
    }
    
    so that when it auto range mode you can retrieve the max and min from the API.

    so if you're not in auto range and you set max to be the same as min we'd see the data is just the raw values, not even scaled to the height of the plot.
    
    Is that what we intend?
