Recent Updates to ZSimpWin V 3.10

Applies to: ZSimpWin V3.20.
Last updated: Saturday March 20, 2004.

The following features have been added to ZSimpWin V 3.10.   

Frequency labels on a complex plane plot

  We can add frequency labels on a Nyquist plot as shown below:

1. Applicable to Nyquist, Admittance, and Capacitance plot styles. 
2. Frequency labels should not be overlapped.
3. No label outside the chart area.  Cannot be too close to the boundaries of the rectangle.   
4. No label over data points.
5. Label font can be “normal” or “bold”.  Selected by the “Large fonts” checkbox.
6. Can enable or disable frequency label display.  Added “Freq. Labels” checkbox in the lower toolbar.

Addition of labels on multiple curves

Multiple curves are defined by a project (*.prj) file.  This file lists the location of impedance data, the location of corresponding parameter files, and the list of estimated parameters.   All the impedance data sets (measured data) should be present in a folder, and all the parameter files (representing calculated curves) should be present in a folder.    See the “Simulation demo.prj” given below:

04/03/2003,  12:01:32 PM

C:\Program Files\ZSimpWin\report\Simulation demo.grp

C:\Program Files\ZSimpWin\data\simulation data\

C:\Program Files\ZSimpWin\par\simulation par\

    3                    = the number of files

R(QR(CR)(CR)), R(QR(CR)(CR)).par

R(QR(CR)(LR)), R(QR(CR)(LR)).par

R(QR(LR)(LR)), R(QR(LR)(LR)).par

Impedance data filename is derived from data folder name and parameter filename.   The data file corresponding to the first parameter file will be  “C:\Program Files\ZSimpWin\data\simulation data\ R(QR(CR)(CR)), R(QR(CR)(CR)).* where “*” is the file extension.   The data file can have the extension of  “dat”, “sim”, “ext”, “txt”, “dta”, “z”, or “z60”.  The first extension (“dat”) has the highest priority and the last one the lowest priority.   If several files with different extensions exist in the data folder, the one with the highest priority will be taken as the data.  ZSimpWin does not save calculated data points.  Calculated curve is obtained from the parameter file. 

When multiple curves (for 7 data sets maximum) are presented in a chart, frequency labels are drawn in sequence from the first curve to the last curve.  The first curve has the highest priority in claiming a spot in the plotting area.  It is not possible to change the order of the parameter files in the list because the filenames are sorted automatically.   To change the order, assign file names such that they would be listed in desired order. 

The data shown in this example were prepared by running in simulate mode (Run | Run in Simulate Mode), saving simulated data as data points (“.sim”) (File | Save Simulation Data), opening the data (File | Open), running in iterate mode (Run | Select Mode & Run Mode), and saving analysis results.  

Print item selection

Allows more flexibility in printed output.  Different combinations of plot styles and layout can be selected.    Four plot styles can be printed in a page. 

1. Parameters and current plot in Portrait orientation.
2. Two selected plots (Left-Top and Left-Bottom) in Portrait orientation.
3. Four plot styles (including parameters) can be printed on a single page in Landscape orientation.   Each of the 4 items is to be selected separately.
4. Can save the current layout.   This configuration is loaded at program start-up.

Project Management

Updated this dialog box to offer the same options in the [Print item selection] dialog box.  Only the first 2 or 4 checked items are printed depending on page layout selection.   In the figure shown below, selection of the “2, Left, Portrait”, will lead to printing “Params” and “Z”.   When the “4, All, Landscape” is selected, the fifth item “Y” will be neglected.

Pop-up Menu

Reorganized and updated to provide a higher efficiency in operation.   Some users might feel more comfortable in using this menu rather than speed buttons.

Save plot

Fixed bugs and improved its performance.  Default graphics data format can be changed from the [Run | Options] menu.  When the [Output | Save plot] menu is clicked, a save filename assembled based on impedance data filename, selected model, current plot style, and the data format is suggested, and the message “Save plot with the filename” appears on the screen.  Click on the [Yes] button to save with this name in the …\pics folder.   If you want to change the data format, the filename, or the folder, click on the [No] button.

View saved plots

  Added [Tools | Select Image Viewer] and [Tools | View Saved Plots] menus to allow running an Image Viewer installed on your computer.  If you do not know the exact path and name of the program, right-click on the shortcut of the Image Viewer, click on the [Properties] in the pop-up menu, and read the path and the name of the executable file in the “Target” box.  

  Click [Tools | Select Image Viewer] menu.  A file save dialog box appears on the screen.  Navigate the folder and locate the executable file.  Select the file (e.g., “C:\Program Files\IrfanView\i_view32.exe”), and click on the [Save] button to save this information.  This information is loaded in the next sessions. 

  Click [Tools | View Saved Plots] to view the plots saved in the …\pics folder.
