ColumnChart Visibility

[gisela]

Hi syncfusion team,

I have slightly modified the demo example "ColumnChart":

<div class="control-section" align='center' style="visibility: collapse; height:0px;">

    <SfChart Title="Olympic Medal Counts - RIO" Width="@Width" Theme="@Theme">

        <ChartArea><ChartAreaBorder Width="0"></ChartAreaBorder></ChartArea>

        <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" Interval="1">

            <ChartAxisMajorGridLines Width="0"></ChartAxisMajorGridLines>

            <ChartAxisMajorTickLines Width="0"></ChartAxisMajorTickLines>

        </ChartPrimaryXAxis>

        <ChartPrimaryYAxis Title="Medal Count" Maximum="50" Interval="10">

            <ChartAxisMajorTickLines Width="0"></ChartAxisMajorTickLines>

            <ChartAxisLineStyle Width="0"></ChartAxisLineStyle>

        </ChartPrimaryYAxis>

        <ChartSeriesCollection>

            <ChartSeries TooltipMappingName="MappingName" DataSource="@ChartPoints" XName="Country" YName="GoldMedal" Name="Gold" ColumnSpacing="0.1" Type="ChartSeriesType.Column">

                <ChartMarker>

                    <ChartDataLabel Visible="false" Position="LabelPosition.Top">

                        <ChartDataLabelFont FontWeight="600" Color="#ffffff"></ChartDataLabelFont>

                    </ChartDataLabel>

                </ChartMarker>

            </ChartSeries>

            <ChartSeries TooltipMappingName="MappingName" DataSource="@ChartPoints" XName="Country" YName="SilverMedal" Name="Silver" ColumnSpacing="0.1" Type="ChartSeriesType.Column">

                <ChartMarker>

                    <ChartDataLabel Visible="false" Position="LabelPosition.Top">

                        <ChartDataLabelFont FontWeight="600" Color="#ffffff"></ChartDataLabelFont>

                    </ChartDataLabel>

                </ChartMarker>

            </ChartSeries>

            <ChartSeries TooltipMappingName="MappingName" DataSource="@ChartPoints" XName="Country" YName="BronzeMedal" Name="Bronze" ColumnSpacing="0.1" Type="ChartSeriesType.Column">

                <ChartMarker>

                    <ChartDataLabel Visible="false" Position="LabelPosition.Top">

                        <ChartDataLabelFont FontWeight="600" Color="#ffffff"></ChartDataLabelFont>

                    </ChartDataLabel>

                </ChartMarker>

            </ChartSeries>

        </ChartSeriesCollection>

        <ChartLegendSettings Visible="true" EnableHighlight="true"></ChartLegendSettings>

        <ChartTooltipSettings Header="<b>${point.tooltip}</b>" Enable="true" Shared="true"></ChartTooltipSettings>

    </SfChart>

</div>

So I would expect the chart not to be visible, but the result is:

In the case of other types of charts such as StepArea, the output is correct.

Thanks in advance

Hi Durga,

Thanks for your sample project, here is the chart layout as expected.

You can reproduce the error by adding the specified style for the "Column" ChartType of the Syncfusion Sample Demo project  (BlazorServerDemos_NET6):

You will then get the following output:

Thank's in advance

Hi Gisela,

In the demo sample, we have set the minimum height as 350px for the control section. So, the reported scenario occurs in our demo sample. But if we tried to reproduce this in our sample, we are unable to replicate the same. Please modify the standalone sample to replicate the reported scenario based on your requirement. It will be helpful for us to analyze further and assist you better.

Regards,

Hi Swetha,

I've now attached your demo project with a few modifications (the chart embedded in a div element with class=row).

In my development project I have several  controls (created dynamically)  embedded in rows, that are shown or hidden depending on buttons.

Thanks in advance
