Easy Chart Database Pen problem

Hi, I have an Easy Chart with some database pens, my question is how can I specify a start date and end date? when I select the pens, don’t give that option, I’m using Manual mode.

Start and end are properties of the chart as a whole, not of individual pens. In manual mode, you need to set those properties through scripting, or by binding date entry components, or otherwise bind date computations.

Thank you pturmel!
