Charts disappear when zooming is enabled

[Manfred Unger]

I am testing Blazor Server Side Charts  (SF Blazor 18.2.0.44).

I have 4 Charts on my page which works very fine.

After enabling zoom function (see ChartZoomSettings) I have the following problem:
When zooming in one of the four charts all other charts disappear. Only the one I am zooming in is still on the page.

I have tried to assign each chart a unique ID. I have also tried to give them in div containers with unique IDs.

Nothing helped.

Did I miss something?

After trying a few things my code looks like this:

<div id="control-content">
                @foreach (var track in analyzerTracks)
                {
                    string chartId = string.Format("chart_id_{0}", track.AnalyzerTrackId);
                    <div [email protected]>
                        <div class="control-section">

                            <SfChart ID=@chartId Width="90%" [email protected]>
                                <ChartEvents Load="ChartLoad" />
                                <ChartTitleStyle Size="26px"></ChartTitleStyle>
                                <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.DateTime">
                                </ChartPrimaryXAxis>
                                <ChartTooltipSettings Enable="true"></ChartTooltipSettings>
                                <ChartZoomSettings EnableMouseWheelZooming="true" EnablePinchZooming="true" EnableSelectionZooming="true"></ChartZoomSettings>
                                <ChartSeriesCollection>
                                    @if (analyzerStatisticData != null && analyzerStatisticData.AnalyzerTracks.ContainsKey(track.TrackName))
                                    {
                                        @foreach (string groupName in analyzerStatisticData.AnalyzerTracks[track.TrackName].MaterialgroupValues.Keys)
                                        {
                                            <ChartSeries DataSource="@analyzerStatisticData.AnalyzerTracks[track.TrackName].MaterialgroupValues[groupName]"
                                                         Name=@groupName PointColorMapping="Color"
                                                         Width="2"
                                                         XName="Date" YName="Value" Type="ChartSeriesType.MultiColoredLine">
                                            </ChartSeries>
                                        }
                                    }
                                </ChartSeriesCollection>
                                <ChartLegendSettings Visible="true"></ChartLegendSettings>
                            </SfChart>
                        </div>
                    </div>
                }
            </div>

After updating from version 18.2.0.44 to 18.2.0.55 zooming works as expected.

Thank you very much for your sample project.
