The GUI is implemented through using Tkinter and Pmw. It can handle ASCII or MDA file. It will extract 1D multiple array from any ASCII text file as well as any MDA file. Extracting 1D array from MDA file is obtained by properly handling of the scan data object returned by the readMDA program.
The ASCII file can contain row or column oriented vectors. By default the column oriented vector array is assumed. If the data set is row oriented vector, a user can simply use the 'Row Oriented' entry from Setup menu to convert the row data into column data internally. Any line start with ';' or '#' will be treated as comment and ignored. The text data may or may not contain independent variable vector.
Zero based index sequence number is used in setting up array vectors. By default the first column (0) contains the X vector. The remaining columns starting from the second column (1) contain the dependent variable vectors. User can override the default setting by properly modifying the X or the starting Y sequence index fields.
A collection of sequenced check buttons will be created when the extracted 1D array is loaded in. The total number of check buttons reflects the total number of dependent variables or curves found in file. For each column vector there associates a checkbutton for it. By default only the first two curves are selected for plot a user can easily to change the selections by checkbutton or setup menu.

The active plot window is the current plot window generated. and it can be easily closed by simply clicking the right mouse button. Closing of current active plot window results that the very last generated plot window becomes the current active plot window.
The main window consists of menu bar, a collection of control label input fields, a row of command buttons area, and a set of various popup dialogs. They are described below:
File Menu Load Ascii Data... - use file selection dialog to pick a file, by default it assumed column oriented data in ASCII file Print Plot1d.jpg - created plot1d.jpg and send the color jpg file to a PS printer through pilprinter.py program Printer... - dialog to override the default PS printer Quit - exit the plot1d program Setup Menu Display Ascii File... - display text contents of a picked ascii data file to provide convenient varification of column or row data array and plot curves Row Oriented - treat ascii file as row oriented data array Column Oriented - treat ascii file as column oriented data arrayy (default this is assumed) Select All Checkbutton - select all curve check buttons to be plotted Select None Checkbutton - deselect all checked curve buttons PlotOption Menu Line Style On - checkbutton for using different line styles Grid Line On - checkbutton for drawing grid line Log Xaxis On - checkbutton for logarith X axis Log Yaxis On - checkbutton for logarith Y axis Symbol On - checkbutton whether to plot symbols with curve Setup Symbol... - a dialog to modify the default curve symbols Legend Menu Legend On - checkbutton whether to plot legend or not Default Legend Location - a collection of radiobutton to set default legend location User Legend Location... - a dialog to set the desired legend location Setup Legend Labels... - a dialog to set the legend strings for plotting Analysis Menu Statisic ... - dialog to setup statistics calulation for desired curve Fitting ... - dialog to setup polynomial fitting for desired curve Histogram ... - dialog to setup histogram plot for desired curve Errorbar ... - dialog to setup errorbar plot for desired curve Statistic Dialog Curve # to Pick: - droplist field to specify the picked curve number Close - terminate the statistic dialog Accept - calculate and update statistic info for picked curve Next - calculate and update statistic info for next curve Prev - calculate and update statistic info for previous curve All... - calculate and display statistic for all data curves Statistic Info - label area display statistic info of picked data curve Polynomial Fitting Dialog Curve # to be fitted: - droplist field to specify the curve number Polynomial order #: - field to specify order of fitted polynomial Ok Button - accept entry fields and performed fitting calculation Close Button - terminate the fitting dialog Output Title - field to specify the plot title for fitted result Output Xlabel - field to specify the plot xlabel for fitted result Output Ylabel - field to specify the plot ylabel for fitted result Output Fitting Coeffs - field to display coeficients of fitted result Help Menu About ... - help about the progrm information Balloon Help - checkbutton for balloon info about each menu and button Help Info... - pops on line help about plot1d program Curve Plot Control Label Widgets Title - enter plot title and update current figure Xlabel - enter new xlabel and updagte current figure Ylabel - enter new ylabel and updagte current figure Xrange: Xmin - enter X starting value for plot Xrange: Xmax - enter X ending value for plot Yrange: Ymin - enter Y starting value for plot Yrange: Ymax - enter Y ending value for plot X Column Seq# - specify the column seq # for X vector in data array default 0 indicates first column contains X vector use -1 to indicate file contains no X vector X Row Seq# - specify the row seq # for X vector in data array default -1 indicates file contains no X vector in file Group of Curve Check Buttons CheckButtons - collection of check buttons are created when an ASCII file is loaded in, one button per defined curve By default only first 2 curves are picked, a user can configure the line plot by select/deselect any curve as user prefered Command Button Row Close - close and exit the plot1d program Plot Curves - plot checked column vectors with current control setting, each time a new multi-line plot window is generated Subplots - plot checked column vectors as subplots, at most 9 subplots can be drawn, each time a new subplot window is generated CloseFigures - automatically close all plot/figure windows
The Title, Xlabel and Ylabel fields allows the user easily to modify the plot Title, X label and Y label for the current active plot window. For example, to change the plot title by typing the new string in the field and then followed by pressing the carriage return or 'Enter' key.
