Bar- and candle style graph for stocks

Plots a bar graph of stock OHLC values, o

I needed to plot some bar charts but I haven't got the financial toolbox. I couldn't find one here so I modified Nagi Hatoum's Candlestick Graph script to display bar charts.

I've also updated Hatoum's candlestick plotter, custom colors are available for both bars and candles. Also expanded the number of ways to input data. In combination with tlabel (see acknowledgements), auto-updating dates can be shown on the x axis.

Input instructions are in the file (look at the file or use 'help [fcnname]')
