15.11.1 Introduction

For each X entered, the corresponding Y is added/averaged to a bin in the histogram. If all selected Y and DYs are zero Y and DY are assumed to be 1.0. When averaging any data with zero DY is ignored. The result is an evenly spaced series of X values with the corresponding distribution in Y and the standard deviation of each Y in DY/NDY. The symbol for each bin is set to the default. You may find that the resulting data is not in the correct storage locations especially if a 3-d plot is to be produced. You may change locations with the SWAP command. If the data has a non zero DX then it may be distributed over more than 1 bin. The DX error distribution is assumed to be gaussian, and the data is distributed with a cut off at 4 sigma. If NORMAL=OFF a flat distribution is assumed. You may not BIN mesh data. If you need to rebin mesh data then it should be decomposed to a series of data sets using the PROJECT BY n command.
