[Solved] Line Chart - Nothing but the data

Hi All,

I'd like to make certain that I'm just showing one data line and no legends, tick marks, axes, padding and so on. I would also like the first data point to be the center of the graph vertically.

Here's my chart markup, please let me know if you have any suggestions. Thank you so much.

<TelerikChart Width="100%" Height="100%" Transitions="false" RenderAs="Telerik.Blazor.RenderingMode.Canvas">

<ChartSeriesItems>

<ChartSeries Type="ChartSeriesType.Line" Name="" Data="@Data" Color="@LineColor">

<ChartSeriesMarkers Visible="false" />

<ChartSeriesLabels Visible="false" Background="transparent" />

</ChartSeries>

</ChartSeriesItems>

<ChartCategoryAxes>

<ChartCategoryAxis Visible="false"><ChartCategoryAxisMajorGridLines Visible="false" /></ChartCategoryAxis>

</ChartCategoryAxes>

<ChartValueAxes>

<ChartValueAxis Visible="false"><ChartValueAxisMajorGridLines Visible="false" /></ChartValueAxis>

</ChartValueAxes>

<ChartTitle Visible="false" />

<ChartLegend Visible="false" />

</TelerikChart>

[Solved] Displaying dots on a candlestick chart

Hello!
I am trying to implement a box and whisker chart using a candlestick chart.
Everything looks good, but I can not display outliers in the form of points.
The problem is that you can't mix categorical candlestick chart type and numeric type. Using a categorical type of line chart also does not produce the desired result.
Can anyone tell me how to display a scatter chart on a candlestick chart?

ComboBox filter text behavior

Would be fine if when you click on a filterable combobox the whole text in it will be selected, so you can click and start digit new text filter without delete the old text before.
