When a data item is created in Information Map Studio, the defaults are assigned for classifications and aggregations. If the data item is a percentage, this defaults may not make sense. For instance, the following figure shows the Gross Margin in scientific notation instead of a percentage.
When the data item was imported, the default aggregation method was SUM, which does not work in this case. The gross margin is your profit from this sale and it should remain constant or in other words.
So how do you fix it?
You need to change the default measurement for the data item. For a value like Gross Margin, there is not reason to aggregate this data item – when is a sum of all Gross Margins for a customer or product used?
For this item, the gross margin is associated with the Product data item. Any product no matter to which customer in any region, the gross margin remains constant. You have to select a default aggregation method, so I chose Average. I thought it would make the most sense to the end user. I could have also used Minimum. In the following figure, minimum would have set the value to 70% for the non-aggregated figure.
