Plot combined historical and forecast data to visualize possible outcomes

`fanplot(historical,forecast)`

`fanplot(___,Name,Value)`

`h = fanplot(historical,forecast)`

`h = fanplot(___,Name,Value)`

`fanplot(`

generates
a fan chart. In time series analysis, a fan chart is a chart that
joins a simple line chart for observed past data with ranges for possible
values of future data. The historical data and possible future data
are joined with a line showing a central estimate or most likely value
for the future outcomes.`historical`

,`forecast`

)

`fanplot`

supports three plotting scenarios:

Matching — This scenario occurs when the time period perfectly matches for

`historical`

and`forecast`

data.Backtest — This scenario occurs when there are overlaps between

`historical`

and`forecast`

data.Gap — This scenario occurs when there are

`NaN`

values in the`historical`

or`forecast`

data.

`fanplot(___,`

generates
a fan chart using optional name-value pair arguments.`Name,Value`

)

generates
a fan chart and returns the figure handle `h`

= fanplot(`historical`

,`forecast`

)`h`
