I am trying to make a chart that is variable with the scroll bar
I made the chart and the scroll bar and it's working except the slider part
If I click on the arrows it moves from side to side by one or I can click in between to move by more than one and the slider also works but not dynamically by that I mean when I drag the slider nothing happens on the chart it only changes when I release the slider

When I move the slider I see the values changing in the cells but it's not reflected in the chart until I release the slider
I used the index function to set it up
I also saw it set up with the Offset function but I am nut sure if this would make the scroll function any different
I am doing this with Excel 2003 if that makes any difference

Is it possible to make the slider work dynamically or do I need some code to make it work ?
