# Apply symbol

The action will conditionally apply a symbol (icon) for a cell with a measure and the one of the predefined algorithms: “Positive/Negative” or “Less than 100%”.

### Positive/Negative

"Positive/Negative" algorithm can be used to show icons for postive, negative and zero values by setting appropriate icons.

### Less than 100%

"Less than 100%" algorithm can be used to show icons for values less than 100% and for values greater or equal to 100% by setting appropriate icons.

### Expression

The "Expression" option  allows to map the "Symbol" expression's values to particular icons. To be able to use such option a "Symbol" expression should be set for a measure using the properties panel:

![if("± SALES %" < 0, 'down', 'up')](https://4159443657-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lb8fteihZN5J-edUC8e%2F-MC7Bd6IgVjYftUfA1S-%2F-MC7CYJy0fqL_yuPrHxZ%2FSymbolExpression.png?alt=media\&token=0df349d7-c223-450b-89de-841648975929)

After binding the measure with a cell (in our case the "± SALES %" measure) it is possible to map the "Symbol" expression's values to particular icons:

You can add as many mapping items as needed by clicking the button<img src="https://4159443657-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Lb8fteihZN5J-edUC8e%2F-MC7CdADRqVziySHGNyk%2F-MC7FRevq-LMYzSCovQK%2F%D0%A1%D0%BD%D0%B8%D0%BC%D0%BE%D0%BA%20%D1%8D%D0%BA%D1%80%D0%B0%D0%BD%D0%B0%202020-07-13%20%D0%B2%2015.58.02.png?alt=media&#x26;token=65fe4ad9-f41a-45cf-93f4-66a835bbe7d6" alt="" data-size="original"> next to the "Edit mappings" label. For each added row you need to specify a value (by entering it in the input text field) and an icon (by selecting it from the icon popup menu).
