CandleStick chart with non-Date axis

Post by matW » Fri Jul 06, 2007 2:42 am

Hi,
I'm trying to render candlestick charts with historical data from the e-Mini S&P. My data format (trading technique) is not based on time, but rather on transactions (ie. a new candle forms after every 144 transactions). So i may have 10 candles that form within the space of a minute, or one candle that forms in the space of 5 minutes. When i render this data with the regular candlestick charts i get overlapping candles, or very spaced candles. What i would like is to have the candles evenly spaced, ie. time not scaled. Rather i would like a category type axis where the candles each lie in their own category, with the category values being the times that each candle closed...

Is this possible with the current implementation?

cheers
Mat

if time is not important then maybe you can alter your historical data with arbitrary dates so that they come out evenly spaced
