It seems the issue happens randomly -> crashes on a Windows 19 Server while running a basic Windows Maui app.

There is a public bug report: https://github.com/mono/SkiaSharp/issues/3168   

The signatures are stored in the database as a string, representing the point data of all the lines in the signature.
For example, something like 

"1,2;3,4;5,6;7,8/10,11;12,13;14,15/21,22;23,24;25,26"

Currently, i can use the public method ScrollItemIntoView to scroll to an item in the DataGrid. 

I noticed you have an internal method: ScrollColumnIntoView. Please make it public so I can use it to scroll to a specific column.

For the distinct values, there is a bool property that allows you to hide the distinct values: ShowDistinctValuesFilter. 

Expose similar way for the Show Rows with Values options

Provide an option to sort the template column by nested property. 

For example: 

<dataGrid:DataGridTemplateColumn>
    <dataGrid:DataGridTemplateColumn.CellContentTemplate>
        <DataTemplate>
            <Label Text="{Binding MyAddress.City}" />
        </DataTemplate>
    </dataGrid:DataGridTemplateColumn.CellContentTemplate>
    <dataGrid:DataGridTemplateColumn.SortDescriptor>
        <dataGrid:PropertySortDescriptor PropertyName="MyAddress.City"  />
    </dataGrid:DataGridTemplateColumn.SortDescriptor>
</dataGrid:DataGridTemplateColumn>

when rendering thousands of data, provide fast line chart. This type of series can be used for system performance monitoring or with chart than need to display thousands data points.

WinForms has fast line chart: https://docs.telerik.com/devtools/winforms/controls/chartview/series-types/fastline 

Currently the only buttons which can be navigated to and are interactable using keyboard are the next and back buttons, i.e.:

However, the user is unable to navigate to the 'month' selector or the individual dates:

In addition, if we were to click on the Month label, we also can't navigate or select the month we desire using the keyboard.
