[amibroker] Plotting High & Lows as a line chart

[Paul]

I am new to Amibroker and have previously used Metastock. I want to be 
able to plot on the chart with a line the Highs & Lows. On Metastock I 
just used two 1 day simple moving average one calculated off the high & 
the other calculated off the low. When I tried this with Amibroker it 
will only let me plot a 2 day simple moving average it wont plot down 
to a 1 day moving average. Any help please
