# HISTORICAL PRICE AND VOLUME PLOTS

  # Screen-captured plots of daily mean bitcoin price (log and linear scale) and daily volume,
  # over full history, from BitcoinWisdom.com, of the main available exchanges
  
     pdate="2014-06-29"
     ${pdate}-{EX}-{SEQ}-log.png  Mean daily prices, logarithmic scale.
     ${pdate}-{EX}-{SEQ}-lin.png  Mean daily prices, linear scale.
     ${pdate}-{EX}-{SEQ}-vol.png  Daily volumes in BTC, linear scale.
     
  # where {EX} is the exchange code, one of
  
    exes=( HUBI OKCO BSTP BTCE BTCC BFIN MGOX )
    
  # The {SEQ} is 0 (believed to be the best) or 1 (superseded by 0).

# !!! TO DO:

  # Trim each image to the correct plot area. Beware that the plot size may have changed 
  # halfway through some of the series ("lin", "log", or "vol").
  
  # Collect two points (value and pixel cordinate) for the vertical scale, and the horizontal
  # pixel coordinate of the last data bar (for ${pdate}).
  
  # Extract the data values from the plots.
  
  # Combine the extracted linear- and log-scale data according to their accuracy.
  
  # Check the resulting values with the actual data downloaded from BitcoinCharts.
  
  # Make a combined logscale plot of price.
  
  # Make plots of volume, on the same scale, that can be stacked.
