DxChartAxis - Placeholder size

When the specified area is not enough to display axis labels completely, you can use the TextOverflow or WordWrap property to define how to display such labels.

The following example changes the content area size for the argument axis and uses drop-down menus to choose how to display axis labels:

<DxChart Data="@GetData()" Width="100%" Height="500" Rotated="true">
    <DxChartTitle Text="Pizza Shop Complaints" CssClass="mb-2" />
    <DxChartLegend Visible="false" />
        <DxChartBarSeries ArgumentField="@((DataPoint s) => s.Complaint)"
                          ValueField="@((DataPoint s) => s.Count)" />
    <DxChartTooltip Enabled="true">
        <div style="margin: 0.75rem">
            <div class="fw-bold">@context.Point.Argument</div>
            <div>Complaint frequency: @context.Point.Value</div>
        </div>
    </DxChartTooltip>
    <DxChartArgumentAxis PlaceholderSize="@CurrentPlaceholderSize">
        <DxChartAxisLabel WordWrap="@CurrentWordWrap"
                          TextOverflow="@CurrentTextOverflow" />
    </DxChartArgumentAxis>
</DxChart>

@code {
    ChartTextOverflow CurrentTextOverflow = ChartTextOverflow.Ellipsis;
    ChartWordWrap CurrentWordWrap = ChartWordWrap.Normal;
    double CurrentPlaceholderSize = 55;
    List<DataPoint> GetData() {
        List<DataPoint> result = new List<DataPoint>(7);
        result.Add(new DataPoint("Delayed delivery", 1123));
        result.Add(new DataPoint("Cold pizza", 780));
        result.Add(new DataPoint("Damaged pizza", 321));
        result.Add(new DataPoint("Wrong size delivered", 222));
        result.Add(new DataPoint("Not enough cheese", 120));
        result.Add(new DataPoint("Incorrect billing", 89));
        result.Add(new DataPoint("Underbaked or Overbaked", 52));
        return result;
    }
    public class DataPoint {
        public string Complaint { get; set; }
        public int Count { get; set; }
        public DataPoint(string complaint, int count) {
            Complaint = complaint;
            Count = count;
        }
    }
