I am trying to edit hovertext in figure_factory.create_quiver().

I am visualizing Spatio-temporal data and basically have 5 columns for coordinates (x, y), differences in coordinates (dx, dy) and velocity (calculated by dx and dy).

the exact code I am using now is below.

```
fig.add_traces(
ff.create_quiver(
df['x'],
df['y'],
df['dx'],
df['dy'],
hovertext=df['v']
).data[0]
)
```

When I hover the cursor on an arrow, it only shows the coordinate of one of its edges, not the velocity(`df['v']`

).

Then I looked into the `ff.create_quiver().data[0]`

and found out the lengths of x and y axes and that of `df['v']`

(i.e. length of original df) do not match; x and y axes are twice as long as the original dataframe.

Is it because one arrow consists of multiple lines?

And how can I put hovertext on each arrow?

thanks
