Map rendering when data contains invalid latitude or longitude

The way invalid latitude and longitude data are handled in a map visualization changed. The legend is updated to reflect the removed data point and add a warning message if the domain in the legend changes.

When invalid or missing latitude and longitude data value were encountered, Cognos Analytics remapped the coordinate to [0,0]. As of version 11.1.6 Cognos Analytics does not display the data point on the map at all.

Example of a warning for invalid latitude and longitude coordinates.

In previous versions, when a location string was not matched, then the datapoint was not displayed on the map, and a warning was shown. In IBM Cognos Analytics 11.1 R6, the legend is updated to reflect the removed data point and add a warning message if the domain in the legend changes. If the data points that are removed affect the data domain, IBM Cognos Analytics adjusts the legend that displays the domain to be accurate and displays a warning message.

Example of a warning and how the legend changes.
