I want a chart to update so that I can se either next column or previous
column in the chart. I want the user to push a commandbutton (next column or
previous column) to see data from one column at the time. The first column is
the x- values and the rest is the y- values.

FYI: The X- values are the time axis. The rest of the columns are logdata.
The point is to see how the logdata varies.
