The GetData command returns the Array from a DataSeries object that contains the actual data.

By default, GetData returns the data Array itself: if you modify the values in the returned Array, then the values in the DataSeries object will change. If you use the copy = true option, GetData returns a copy of this Array. You can shorten this option to just copy instead of copy = true. The default is copy = false.

$\mathrm{ds}≔\mathrm{DataSeries}\left(⟨1\,2\,3\,4⟩\,\mathrm{labels}=\left[A\,B\,C\,\mathrm{D}\right]\right)$

$\mathrm{ds}≔\left[\begin{array}{cc}A& 1\\ B& 2\\ C& 3\\ \mathrm{D}& 4\end{array}\right]$

$a≔\mathrm{GetData}\left(\mathrm{ds}\right)$

$a≔\left[\begin{array}{cccc}1& 2& 3& 4\end{array}\right]$

$a\left[2\right]≔-2$

$a_2≔\mathrm{-2}$

$\mathrm{ds}$

$\left[\begin{array}{cc}A& 1\\ B& \mathrm{-2}\\ C& 3\\ \mathrm{D}& 4\end{array}\right]$

$b≔\mathrm{GetData}\left(\mathrm{ds}\,'\mathrm{copy}'\right)$

$b≔\left[\begin{array}{cccc}1& \mathrm{-2}& 3& 4\end{array}\right]$

$b\left[3\right]≔-3$

$b_3≔\mathrm{-3}$

$\mathrm{ds}$

$\left[\begin{array}{cc}A& 1\\ B& \mathrm{-2}\\ C& 3\\ \mathrm{D}& 4\end{array}\right]$

The DataSeries/GetData command was introduced in Maple 2016.
