Mark Borders
| All marks except lines and shapes have a black border. When your view contains a lot of data, mark borders can blend together and sometimes make it hard to identify colors. A common example is a dense heat map or a scatter plot. You can turn off the mark borders to clean up the view and make it possible to find hidden insights. | |||||
Here's how it works.The view below is a heatmap showing product category performance in terms of profit and discount by region and market segment. The size of each mark represents the total discounts while gross profit is encoded as color. With the mark borders turned on, it is difficult to distinuguish the profitability of the product categories with fewer sales. |

| This view shows the SUM of the Sales field for each product in Product Category 4. You can scroll through the list of thousands of products and search for the ones you are interested in, or you can create a computed set containing just the top products. | |||||
| To toggle the mark borders on and off, select Format > Show Mark Borders. | |||||

| You can see that without the mark borders, some findings become visible. For instance, it is now quite clear that the office chairs in the western region are bringing debt rather than profit. | |||||

| Note:Another way to inspect dense data is to manually sort the order in which marks are drawn. For example, in a scatter plot where marks overlap, you can re-order the marks by rearraning the color legend. | |||||
