Candlestick Spread Charts

Was wondering if anyone knows of a charting package which is capable of plotting candlestick spread charts for pairs trading.
I am using Qcharts now but its recent unreliability has become unacceptable. Realtick is not capable of candlestick spread charts and I find eSignal's charts insufficient. Any other alternatives out there?
Thanks.
 
it seems esignal 7.4 does
