I have a long series of charts (approx. 10 feet) that I need to extract data from. Is there any software that can read from a scanned picture of the chart (in A4 bits) and extract the chart values, whilst excluding the chart background?
Thanks IR. The Tracer software, you mentioned, I found on the web but appears to be for bar codes in shops. Whether there is another for scanning along a chart I don't know. I did find one, however, that can do charts from an A4 scan, which will save me a lot of time and effort.
