By configuring the color ranges, you can assign any color change to each bar depending on its value.

Each range has a minimum and maximum value, a normal color and a limit color displayed outside the limits.

A signal must be assigned to each bar. The signal value is used to determine the bar’s colors with reference to the range settings. The Id column refers to the existing bars. Basically, the same signals as used for the bar values can be used again for the color ranges. Drag the signal to the desired line of the signal table or select the line of the desired bar and double-click on the suitable signal in the tree.

The individual assignment of signals enables you to determine for which bar the color range should apply or not.

However, you may assign other signals for controlling the color than the bar values. For instance, you can define a bar’s color by a state or a fault signal instead of the bar value itself.

Make sure that the Min range and Max range values comply with the signal assigned in the color range mapping table.

If you leave a line empty, the corresponding bar will use the default colors.

If the value of a signal defined for color range control is outside the range, the bar will be displayed in default colors.

If you like to use limits and the corresponding limit colors, make sure the color range covers the entire signal value range, including values inside and outside the limits.

Example:

The chart above is the result of the following settings and values.

Color ranges:

	Value	Mapped to color range	Comment
Lower limit	-50		Lower red horizontal line
Upper limit	60		Upper red horizontal line
Bar no. 1	55	Yes	In color range 0 – 100, inside limits
Bar no. 2	80	Yes	In color range 0 – 100, outside upper limit
Bar no. 3	-27	Yes	In color range 0 – -75, inside limits
Bar no. 4	-65	Yes	In color range 0 – -75, outside lower limit
Bar no. 5	-99	Yes	Out of color range, default colors
