Original Message (ID '42231') By yehuda:
You use DataRange when not having the "x" part The default Mathematica behavior is to use successive integers and DataRange changes this default You mention that you have two columns, that is, the "x" part is set, so DataRange cannot take place If you want to change this, assuming that your points a evenly spaced between the minimum and maximum values of the horizontal ("x") axis, you can omit the "x" part and then use DataRange or modify the values using Map or ReplaceAll yehuda
