John Madarasz: Log and Semi-log are one in the same. Assuming you are referring to linear and semi-log (log) scale differences I'll explain: Linear scale plots the price axis giving equal weighting to each price unit. QCOM chart example of a linear plot.. lgscharts.homestead.com Semi-log scale plots the price axis on a a percentage basis. (IE: A move from 4 to 8 looks the same as a move from 40 to 80 on the chart, as they are both doubling moves. I discovered back in 1985 that charting the markets using the semi-log scale resulted in a better read of investor sentiment.)
