IDL Wavelet Toolkit User's Guide

20 Chapter 2: Using the IDL Wavelet ToolkitWavelet Toolkit Dataset ViewerYour dataset can consist of several different variables, each with a different dataformat. The Dataset Viewer, located in the middle of the Wavelet Toolkit applet,allows you to organize and manipulate your dataset.The variables are assigned a number and a name derived from the Variable name.You can sort the variables using the Move Variable Left and Move Variable Rightbuttons.Variable InformationEach variable contains a one-dimensional vector or two-dimensional array of datavalues. The data values can be of any numeric type, such as BYTE, INTEGER,FLOAT, etc.The variable also has several descriptor fields which you can modify, describedbelow and summarized in the table below. To modify a field, double-click with theleft-mouse button on the field. After editing the field, press the key to keepyour changes or, click outside of the table to discard your changes.TypeThis string shows the numeric type and the array size of the data. It is not modifiableby the user.TitleThis string contains the overall name of the variable. The Title field is used to labelthe Wavelet Power Spectrum and Multiresolution widgets. The default is the null('') string.VariableThis string provides a short name for the variable. The Variable is used to label plots,and for the labels in the Dataset Viewer. For a one-dimensional vector (e.g. a timeseries), the Variable is equivalent to Ytitle. The default is either the name of theimport file, or 'Data' if imported from the IDL> command prompt.UnitsThis string gives the units of the variable, and is used to label various plots. For aone-dimensional vector (e.g. a time series), the Units is equivalent to the Yunits. Thedefault is the null ('') string.Wavelet Toolkit Dataset ViewerIDL Wavelet Toolkit
