===== Can I visualize multiple index patterns in a single visualization?
You can create *Bar*, *Line* and *Area* charts from multiple index patterns.
Each *Layer* in a visualization is associated with an index pattern and mutiple *Layers* can be combined together within the same visualization. Each *Layer* also has a chart switcher button in order to select the best type of visualization for the specific dataset.
You can also change the index pattern for a single *Layer*.

*Lens* provides a set of features to handle missing values for *Area* and *Line* charts, which is useful for sparse data in time series data.
To select a different way to represent missing values, open the *Visual options* menu, then select how to handle missing values. The default is to hide the missing values.
