It can extract 2D array from ASCII text file as well as from multiple 2D image arrays from MDA 2D/3D scan file.
The GUI is implemented through using Tkinter and Pmw. It can load any text file of 2D array data into plot2d whether the data contains row or column oriented vectors. Any line starting with ';' or '#' will be treated as comment and ignored. The text data may or may not contain independent variable vector. 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.
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. To update the plot title by typing the new string in the field and followed by pressing the carriage return or 'Enter' key.
Please refer plot2d for functions and class object methods defined in plot2d.py.

plot2d.config - configuration file to remember the last MDA and TXT directories used *.txt - contains row / column oriented 2D image data file *.mda - any 2D/3D MDA scan files which contains 2D image arrays 1.txt - temporary text file to hold the row oriented 2D data array to pass to 3dgraph.py surface plot program *.png - various png file name can be used for storing various image or line plot plot2d.jpg - current figure saved to plot2d.jpg before sending to PS printerAt present the matplotlib can only save the plot as PNG file, and the python program pilprinter.py can only print JPEG file. Therefore on UNIX system the PS print job is automatically processed like below:
- first saved the plot as intermediate 'plot2d.png' file - then use PIL image save function to convert to 'plot2d.jpg' - then pass 'plot2d.jpg' to pilprinter.pyOn WIN system the MicroSoft Photo Editor is used to show the image and which let the user easily print the image plot.
Every menu item end with '...' indicates there is a new window asscociated with it. The active plot window can be easily closed by simply clicking the right mouse button (button 3). The active plot window is the current plot window generated. Closing of current active plot window results that the very last generated plot window becomes the current active plot window.
Figure 0 is reserved for panimage of 2D images found in 2D/3D MDA files. Each row contains 10 images/detectors and image figure is placed sequentially row by row starting from the top left corner. There are 2 button events asscociated with the panimage window:
button 1 - click the thumbnail image area to pop up the desired detector 2D TV image button 3 - close the panimage window (figure 0)There are 3 click button events asscociated with each 2D TV image window:
button 1 - update the cursor values label in the main window to reflect the X,Y,Value at the cursor location button 2 - pop up the X-horizontal and Y-vertical line profile windows cross at the cursor location button 3 - close the current TV image window
Menu Bar - hold various program control menus Plot Labels: Title - fields used to modify plot title of current figure Xlabel - fields used to modify plot xlabel of current figure Ylabel - fields used to modify plot ylabel of current figure X,Y,V Ranges: Xrange Imin - image ROI X range start index # Imax - image ROI X range end index # Yrange Jmin - image ROI Y range start index # Jmax - image ROI Y range end index # Array Vmin - minimum of image array value Vmax - maximum of image array value 2D Columns Data: XCol vectore seq # - specify the zero based X column vector # in ascii file, enter -1 if no X vector defined YCol start seq # - specify the Y vectors start column seq number 2D Rows Data : XRow vector seq # - specify the zero based X row vector # in ascii file, enter -1 if no X vector deined YRow start seq # - specify the Y vectors start column seq number Cursor Values ? - label field to reflect the image values at the click of button 1 Command Button Area Close - button close all windows and quit the plot2d program CloseAllPlot - button automatically close all plot figures
