[amibroker] Importing Intraday Data

["Esteban" <ygroups@xxxx>]

I'm having difficulty importing intraday 
data into Amibroker. My import file is csv in the form 
Date,Time,O,H,L,C,Volume,Open Interest. It is one minute per line.
<FONT face="MS Sans Serif" 
size=2> 
Using the ASCII Import Wizard, the file 
is imported without a hitch. But after import there is no intraday data to 
view. The daily chart built from this underlying data shows on the chart sheet. 
Selecting View-Intraday shows all the different intraday intervals blanked 
out.
 
I'm a complete novice with AmiBroker. 
Would someone nudge me in the right direction please?
