It is a widget application and provides simple user interface for tailoring various plot options and labeling features on the final plot. It allows the user dynamically to reset the selected lines, line styles, plot title, plot margins, X label, Y label, legends, comments, etc.. Two types of PS plot are available: drawing area dump or PS plot.
Many plot options can be settable on the command line through the keyword specification.
The widget window associated with PLOT1D program is readjustable by the window manager.
source /usr/local/rsi/idl_5.3/bin/idl_setupIn order to access IDL programs installed in the local epics/extensions/bin, a user has to make sure that the following two environment variables are set before invoking IDL :
setenv EPICS_EXTENSIONS /usr/local/epics/extensions setenv IDL_STARTUP $EPICS_EXTENSIONS/bin/$HOST_ARCH/viewer_startup.proand make sure the directory /usr/local/epics/extensions/bin/$HOST_ARCH is in his/her IDL search path.
IDL> plot1d, [X,] YThis commnad will automatically load the plot1d.pro, PS_open.pro and xdisplayfile.pro program into the IDL session and initially all the lines defined in the data array Y are plotted. The optional variable X specifies the independent X vector values. The variable Y should contains either a single line of 1D vector or multiple lines of 1D data vectors (i.e. a 2D array).
The number of data points in X vector and Y array must be the same. If the variable X is not specified by the user on the command line the index vector of the number of the data point in Y vector is assumed.
A user then can use the various features of plot1d program to tailor the line plot according to his desire.
The buttons labeled with the suffix ... indicates there is a window or widgets associated with it.
If the background color is red a user may have problem to see the red curve drawned, a user can reverse the background color or try to use a different color table.
The drawing area plot dynamically reflects the plot option changes through the features in the user interface in the plot1dSetup dialog.
Data... - Tabulate plot data in plot1d.txt file , call xdisplayfile to display data, and pop up rename_dialog to save as a permanent file Rvs Bkg - Reverse the background color Options...- Pop up plot1dSetup dialog. Printer...- Pop up PS printer setup dialog. Print - Dump the drawing area to PS printer PS Plot - Send plot to PS driver Close - Close the plot1d programIf the 'Data...' button is pressed, then the file 'plot1d.txt' will be created in the current working directory. It should contains tabulated columns of X, Y data array. A user has the option of save it as a permanent file through the reanme_dialog.
If any other intermediate report text file to be displayed by plot1d, the user can use the keyword REPORT='Rptname' to add 'Rptname...' report button.
Both the 'Print' and 'PS Plot' buttons will save the POSTSCRIPT file 'idl.ps' and send the PS plot to the default or selected printer.

All - Toggle button for all curves from Y array Help... - Help info about multiple selection list Even # - Select even number of curves from Y array Odd # - Select odd number of curves from Y array List - Scroll curve list for multiple selectionPress the toggle button 'All' selects all curves or just first curve. Click any item # from the scroll list just selects that curve. Click a # from the list while hold down CNTL key adds the item to the selected list. Click a # from the list while hold down SHIFT key adds all the items between the current and last clicks.

XLegend - Slider to set normalized X location for legend strings YLegend - Slider to set normalized Y location for legend strings LegendStr: - Text widget to show legend strings of selected curvesDrawing the legend strings with the curves is meaningful only if a few curves are plotted. The defualt legend string is composed of 'curve'+'#'. To modify the legend string by highlighting the string and typing directly on the string and finished with the press of the Return key.
Peak X=... Y=... < X Position at Peak Y> H-Peak Y=... < Half Value of Peak Y> Centroid ... < X position of Centroid> FWHM ... < Full-Width-Half-Maximum at the Peak> Mean = ... < Mean of data points> Standard Dev = ... < Standard Deviation of data > Mean Abs Dev = ... < Mean Absolute Deviation of data > Variance = ... < Variance of data > Skewness = ... < Skewness of data > Kurtosis = ... < Kurtosis of data >
Since each curve has it's own FWHM window, if more than 10 curves selected only the first 10 selected curves will pop up. A user can use the SelectCurves list widget to pick different curves to be examined.
There is a 'fwhm.rpt...' button to access the current fwhm report. The temp file 'fwhm.rpt' is used for storing the detailed data information. Since all FWHM windows share the same report filename, therefore only the most current FWHM calculation is accessible thru this button. If user want to view detail fwhm report, one curve should be picked at a time.
