Previously, the Insight object key is displayed when plotted in charts because the key is stored as the custom field value.
However, it is not intuitive thus we decided to retrieve and display the Insight object name.
Labels with very long words and languages without space between each word (e.g. Chinese) are now split into multiple lines as well.
Labels are also limited to a maximum of 3 lines to avoid overlapping labels. Any labels longer than that will have ellipses appended to the last line.
