Column Chart Bar Width and Spacing

I achieved the following result with these settings.

<RadzenChart style="width: 500px">
    <RadzenColumnSeries Data="@revenue2020" CategoryProperty="Quarter" Title="2020" LineType="LineType.Dashed" ValueProperty="Revenue" />
    <RadzenColumnSeries Data="@revenue2019" CategoryProperty="Quarter" Title="2019" ValueProperty="Revenue" />
    <RadzenColumnOptions Radius="10"  />
    <RadzenValueAxis Formatter="@FormatAsUSD">
        <RadzenGridLines Visible="true" />
        <RadzenAxisTitle Text="Revenue in USD" />
    </RadzenValueAxis>
</RadzenChart>

Bottom border radius is not supported though.
