覆盖 WPF 工具包图表中的 DataPointStyle

问题描述

我想在我的 WPF 工具包 Chart 中覆盖 LineSeries 的 DataPointStyle:

I'd like to override the DataPointStyle of the LineSeries in my WPF Toolkit Chart:

<chart:LineSeries>
    <chart:DataPointSeries.DataPointStyle>
        <Style
            BasedOn="{StaticResource {x:Type chart:LineDataPoint}}"
            TargetType="{x:Type chart:LineDataPoint}">
            <Setter Property="Width" Value="20" />
            <Setter Property="Height" Value="20" />
        </Style>
    </chart:DataPointSeries.DataPointStyle>
</chart:LineSeries>

但是，当我这样做时，我丢失了每个系列具有不同颜色的自动调色板着色.应用 DataPointStyle 会使它们全部变为橙色.

However when I do this I lose the automatic palette coloring where each series has a different color. Applying a DataPointStyle causes them all to turn orange.

推荐答案

在有人提出更好的方法之前，我已经手动设置了颜色.我想我暂时不会使用自动调色板.

Until someone suggests a better method, I've manually set the colors. I guess I won't be using the automatic palette for now.

<Style
    x:Key="SimpleDataPointStyle"
    BasedOn="{StaticResource {x:Type charting:LineDataPoint}}"
    TargetType="{x:Type charting:LineDataPoint}">
    <Setter Property="Width" Value="20" />
    <Setter Property="Height" Value="20" />
</Style>

...

<chart:LineSeries ... >
    <chart:DataPointSeries.DataPointStyle>
        <Style
            BasedOn="{StaticResource SimpleDataPointStyle}"
            TargetType="{x:Type charting:LineDataPoint}">
            <Setter Property="Background" Value="Green" />
        </Style>
    </chart:DataPointSeries.DataPointStyle>
</chart:LineSeries>
<chart:LineSeries ... >
    <chart:DataPointSeries.DataPointStyle>
        <Style
            BasedOn="{StaticResource SimpleDataPointStyle}"
            TargetType="{x:Type charting:LineDataPoint}">
            <Setter Property="Background" Value="Red" />
        </Style>
    </chart:DataPointSeries.DataPointStyle>
</chart:LineSeries>
