You can apply conditional formatting by defining thresholds in a story, or you can apply the formatting to all stories based on a model by defining thresholds in that model. For example, in your model you could define a threshold for revenue at $1,000,000, so that all stories based on the model would have a revenue threshold of $1,000,000.
Thresholds can be applied to account dimension members and measures.
Conditional formatting covers several options, including thresholds in models and stories, and assigned colors in stories.
Define Thresholds in a Story
To define thresholds in a story, choose Conditional Formatting from the main toolbar (or the More menu). From there, simply define your criteria for the formatting, including the colors and display options. Once the conditional formatting is defined, you can apply it to charts or tables on your story pages.
Apply to a Chart
You can apply conditional formatting to either a measure in a chart or to the Color definition for a chart in the Builder pane.
Apply to a Table
You can apply conditional formatting to a measure in a table in the Builder pane. You can also define a new threshold, just as you would from the main toolbar.
