Color Adjustments
You can make adjustments to affect the color in the grid image. These changes are applied equally
to the entire layer.
Contrast
Use the Contrast scroll bar to adjust the contrast in the image. Slide the bar between 0 and 100% to
set the grid’s contrast level. You can use the cursor keys for fine adjustment.
Brightness
Use the Brightness scroll bar to adjust the brightness in the image. Slide the bar between 0 and
100% to set the grid’s brightness level. You can use the cursor keys for fine adjustment.
Translucency
Use the Translucency slide bar to adjust the translucency for the image. Translucency can be set
between 0 and 100%. An image with 0% translucency is completely opaque (cannot be seen
through). An image with 100% translucency is completely transparent (completely invisible).
Gray scale
Check to show only gray scale colors in the grid.
Flip Colors Button
Click this button to invert the inflection colors. This affects only the beginning and ending colors at
this time.
Inflection Point Settings
The inflection point settings allow you to set the method used to calculate inflections to show how
your data is distributed across an area. Equal Cell count and Custom Cell Count are based on
percentages. Equal Value Ranges and Custom Value Ranges are based on values.
Equal Cell Count
Sets the inflections so that approximately an equal number of grid cells falls within the calculated
percentage ranges.
Equal Value Ranges
Spreads the inflections between the minimum and maximum of the source data range, where each
inflection value range is the same size.
Custom Cell Count
Choose this method when you want to use your own percentages and not ones that are evenly
spread.
Custom Value Ranges
Choose this method when you want to use your own values and not ones that are evenly spread.
Number of Inflections:
Select from a list of 2 to 16 inflections or type a number between 2 and 255.
Round:
Choose from a list of rounding factors to be applied to inflection values. You may not see the effects
of this rounding if the spread method is based on cell count until inflection values are actually
calculated.
