See the specific tutorial on “Adding Images” for more information on this custom cell.
Percentage Graphic
The cell formula result may be:"next" or "previous" indicating the input cell containing the percentage, or the percentage itself.
The unique custom cell properties are shown below.
The shape options are shown below.
Formulas can be used for the various color options. Left clicking on the label (i.e. “Bar color”) presents a menu of color options as shown below. Choosing one sets the formula text accordingly.
Shown below are a label cell and a custom cell in the design mode.
Consider a cell with the formula
= @current / 8
The output from these 2 cells is shown below with values of 1, 3, 6, and 8.
Graphic
The cell formula result is the name or code of the graphic to show. There are options for foreground color, background color and shapes.
The unique custom cell properties are shown below.
The name options are shown below.
Below are examples of its results from the “example/Custom cells/Graphic Shapes” template.
Formulas can be used for the graphic colors. Below is one for the fill color.
= compareValue(43, 4, "#00FF00", "#FFFFFF", "#FF0000")
The signature for the compareValue() function which compares 2 values and returns one of the 3 possible values.
result = compareValue(value1, value2, lessThanResult, equalResult, greaterThanResult)
This technique can also be used for regular cell background or foreground colors. For example,
compareValue(@cellValue, 200, 'lightRed', null, ' paleGreen')
Unicode Symbol
The cell formula result is the numeric Unicode value. See the mapping tables at https://jrgraphix.net/r/Unicode.
Below are examples of its results from the “example/Custom cells/Unicode symbols” template.

The codes listed at the web site above use hexadecimal notation. The custom cell requires a numeric value. Below is a formula to easily convert between hexadecimal and decimal values.
Shown below are a label cell and a custom cell in the design mode.
The output from these 2 cells is shown below.
Smiley
