Hi all,

I have a line chart that I would like to be able to recreate and plot
another data series. My problem is that it is a chart that was sent as a
print out and I am not able to get the data is plotted in the chart. My
first thought are to apply a grid to the picture (chart) and approximate the
data points. Does anyone know of another way to do this?

Thanks for the reply. Looks like it will do the trick. I also found a
spreadsheet at Andy Popes website, bmp to chart.
http://www.andypope.info/fun/bmpconvert.htm With it I was able to determine
the data points by using the spreadsheet and floating the courser over the
xy coordinates and then calculating their position in relationship to the
minimum xy values, and then plot them on my new chart.

Again, Thanks for the reply.
