What will be returned by h=voronoi(...) in R2018 version.

According to the doc of voronoi, it seems h would be a a vector of two chart line handles in h=voronoi(...). In R2014b it's true.

```matlab

h(1)

ans =

Line with properties:

Color: [0 0.4470 0.7410]

LineStyle: 'none'

LineWidth: 0.5000

Marker: '.'

MarkerSize: 6

MarkerFaceColor: 'none'

XData: [1x200 double]

YData: [1x200 double]

ZData: [1x0 double]

Show all properties

```

h contains the information of edges and vertices.

While in R2018, it becomes

```matlab

h(1)

ans =

handle to deleted Data

```

and all the data are gone.

Is there any way that I can get the same data on R2018 as what I did in R2014?
