It's not scrollable vertically in case of LiveCharts in WrapPanel of WPF,

Question

I implemented the presentation of several charts by the LiveChart in ListBox. It works well. It's displayed by wrapping charts on page space automatically. But, It's not scrollable vertically.

It's scrollable horizontaly when I set ScrollViewer.HorizontalScrollBarVisibility as Enabled as 1 line with a horizontal scrollbar.

But, It is not the result what i want by using the wrapPanel.

Do you have this kind of experience? Please help me.

<StackPanel Orientation="Vertical">
<ListBox ItemSource="{Binding info}" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
  <ListBox.ItemsPanel>
    <ItemsPanelTemplate>
      <WrapPanel/>
    </ItemsPanelTemplate>
  </ListBox.ItemsPanel>

  <ListBox.ItemTemplate>
    <DataTemplate>
      <StackPanel Width="350" Height="250">
        <lvc:CartesianChart>
          <lvc:LineSeries Values="{Binding data}"/>
        </lvc:CartesianChart>
      </StackPanel>
     </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>
</StackPanel>

Make sure that there is no `StackPanel` among the visual ancestors of the `ListBox`. — mm8, May 16 '19 at 10:14
@mm8 I am sorry that it does not work yet when I try `StackPanel` in vertical orientation. — yaho cho, May 16 '19 at 10:42
The comment was meant to say that there should *not* be a StackPanel. Neither as direct parent of the ListBox, nor somewhere higher in the visual tree. Use a Grid or DockPanel instead. — Clemens, May 16 '19 at 11:24
Yes. It's little bit complicated. Now, It is current hierarchy: ``. — yaho cho, May 16 '19 at 11:31
@Clemens I thought that the reason was `livecharts`. Thanks for your help. — yaho cho, May 16 '19 at 12:07

The reason why you don't get a vertical scrollbar is that you have put the ListBox in a StackPanel. A StackPanel measures its children with infinite vertical space if its Orientation property is set to Vertical:
