Contouring range
By default, WinPICS uses the full range of values in your data. However, you can narrow this range by changing the maximum and minimum values.
- - Select this check box to change the maximum value for the contour lines. Any values higher than this value will be excluded from the contour.
- - Select this check box to change the minimum value for the contour lines. Any values lower than this value will be excluded from the contour.
- The top and bottom values match the values displayed in the color bar.
Contour drawing
WinPICS will save your selections
as the default settings for these attributes.
Primary Line
- Frequency - The frequency value corresponds to the interval selected, to determine how often the bold (secondary) contour will be displayed.
- Width - The width value determines
the thickness in pixels to display the contour line.
- Style - Set if the line appears solid, dashed, etc.
- Color - Click this box to open the Color
dialog box, where you can set the line's color.
Secondary Line

to determine how often the contour label will be displayed.
