Frequency labels on a Nyquist plot
Applies to: ZSimpWin version on evaluation after V 3.10
Last updated: Sunday March 23, 2003.
This
plot was obtained by copying the displayed plot to Windows clipboard (Copy plot)
and pasting to a Microsoft Word document (MS Word document).
Implementation
- Applicable
to Nyquist, Admittance, and Capacitance plot styles.
- Maximum
number of labels is 30.
- Label
font can be “normal” or “bold”.
Selected by the “Large fonts” checkbox.
- Limited
number of labels in the region crowded with many points.
- Can
enable or disable frequency label display.
Added “Freq. Labels” checkbox in the lower toolbar.
- Chart
color (outside of the charting area) is changed from silver to white when
the “Freq. labels” checkbox is checked.
Added to have a white background in captured screen.
- The
chart, CDC picture, iterate mode run statistics, and frequency labels are
assembled as a bitmap, and copied to Windows clipboard.
Saved Microsoft Word document contains all the items on the screen.
- For
other plot styles, chart is copied to clipboard in Enhanced Metafile format
(EMF). Higher resolution is
provided with this format for an output printed from the screen.
The
default format to copy a graphics image to Windows clipboard is Enhanced
Metafile format (a vector format). This
format provides a high resolution. We
have created a bitmap containing the chart, CDC picture, iterate mode run
statistics, and the frequency labels, and then copied to the clipboard.
BMP format led to a lower resolution in the output generated with Save
Plot and Print plot menus.
The labels on a chart, located on a different layer, could not be printed directly from the screen (Print plot) or included in the saved picture file (Save plot).
Screen Capture
To
save the displayed plot as a picture file, you must use a screen capture utility
program.
You
can use a simple program such as Capture Plus 2.0. This program works as follows:
- Setup
configuration (the folder to save captured files, graphics format (BMP or
JPG), and file name (NAME).
- Run
Capture Plus. This program stays in the toolbar.
- Run
ZSimpWin.
- Press
Alt – PrtScr to capture the active window.
Captured files are saved as **NAME.BMP, or **NAME.JPG, where ** is a
sequential two digit number.
- Remove
the main menu and toolbars included in the plot using other graphics editor.
Alternatively,
you can use a full-featured graphics application such as IrfanView to capture
the client area. The main menu and
the toolbars included in the plot should be removed (cropped) before saving the
picture.
Plan
After
further testing and evaluation, this feature will be included in the next
release.
