An image of a chart or a bounding box that has a message is displayed instead of the chart in Office 2016 applications

When you save a document that contains a chart and the chart uses one of the new chart types (a treemap, sunburst, histogram, box and whisker, Pareto, or waterfall chart) in Office 2016 applications, the chart parts in the XML are marked as the same content type as a chart of the older chart types (such as a column or pie chart). However, the new chart parts need their own content type, and shouldn't rely on the old content type. Additionally, if you save the document as an ISO strict file format, incorrect namespace URIs are used (transitional URIs are used instead of strict URIs).
