• Here you can change and set permanently many program options.
  
  
• The settings are written to the file spekwin32.ini in the program folder. Write access is needed for this file!
  
  
• During program start, these settings are read from the file. Without write access, the settings can be read but not written. It is recommended to install Spekwin32 to a folder with write access
  

2. Menu Item [Axes]
for interconversion of different axis types and naming of axis titles.

• For the x axis, wavelength, wavenumbers and electron volts scale can be selected. Wavenumbers and electron volts are proportional to energy. The following equation holds true if the axis units are nm and 1/cm:
  and Further: 1eV=8056,5 cm^-1
  
  
• There is the option to manually set the x axis boundaries in the [boundaries] window.
  
  
• the y axis values can be shown as transmittance T, absorbance A, molar absorption coefficient and log(absorption coefficient) . For interconversion, the following equations are used:
  A=-logT and A=cd
  Additionally, the y type "Reflectance" and "Intensity" are recognized and handled by Spekwin32.
  
• For displaying and you have to assign a concentration to the spectrum. This can be done in the menu items [General] or [Concentration].
  
  
• If possible, the x and y axis types are choosen automatically according to the most recently opened spectral file.
  
• The display of axis titles can be turned off with the option [show Axis Title]. Set your own individual axis title with [Set Axis Title].
  
• The option [Alternating Tick Label] will be enabled by default when set in the menu item [Configuration].
  
  

3. Menu Item [Axes Font]

• For changing the font of both axes' tick labels.
  
  

4. Menu Item [Legend Font]

• For changing the font of both axis titles and of legend titles.
• Hint: When choosing very big font sizes, the axes titles and axes labels might overlap.
  
  

5. Menu Item [Legend on/off]

• For turning on and off the display of legend titles.
  
  

6. Menu Item [Grid on/off]

• For turning on and off the grid display.
  
  

7. Menu Item [Secondary x Axis on/off]

• For turning on and off the complementary second x axis at the upper edge of the graph.
  
  

8. Menu Item [Points/Lines]

• For switching spectral display as points or lines.
  
  

9. Menu Item [Flip X-Axis]

• For switching x-Axis direction. Affects only graphics display. Data will be saved in default direction.
  
  

10. Menu Item [Standard Lines&Colours]

• For setting back spectral display to default values. The colours are set to default order, line width to 1 and line style to "solid".
  
  

11. Menu Item [Thicker Lines]

• Increase the line width by one.
• Possible range is from 1 to 7.
  
  

12. Menu Item [Thinner Lines]

• Decrease the line width by one.
• Possible range is from 1 to 7.
  
  

13. Menu Item [Plot All Black]

• Set the line colour of all spectra to black.
• To go back, call the menu item [General] once.
  
  

14. Menu Item [Cycling Line Types]

• Sets the line types of all spectra to alternate between "solid", "dotted" and "dashed".
• To go back, call the menu item [General] once.
  
  

15. Menu Item [Display Values]

• Continuously shows the current x and y value for the spectrum selected in the drop down list.
• Close with [Abort].
  
  

16. Menu Item [Background Colour]

• For changing the graph's background colour.
• Will not be plotted, exported or saved, the background remains transparent!
