Re: [amibroker] Plotting discrete values?

["Steve" <avalon-ardy@xxxxxxxxxxxxxxx>]

Thanks Graham,
both your solutions work, but this causes a stair stepping effect i.e. the 
value is held & plotted until a new value is inputted. I was trying to plot 
single point values much like a regular line chart but with irregular time 
interval. i.e instead of plotting the close every hour, plot the close only 
at specific time intervals
Thanks again for taking the time to respond.
cheers
