Hello K,

Thanks for a new reference.. This is entirely a new one.

What I am expecting is a single chart ,a horizontal histogram, the base of the histogram is in y axis rather than the usual x axis, with space inbetween bars, like in a bar chart, where each bar will represent a different stock and the length of the bar representing the price.

Re: Amibroker AFL needed for Horizontal bar chart for each day for multiple scripts

Hello Singh,

Thank you for your reply. I am looking for Amibroker AFL to do this realtime.

Hence not preferring excel now.
