Question

我有一些我尝试阅读的csv文件，然后将它们分成两列或列表并在数学图表中绘制它们。 csv文件包含两列，一列用于电压，一列用于时间。我阅读了csv文件并使用Interactive Data display

Xaml文件是根据：

<GroupBox Grid.Row="1" Grid.Column="0" Header="Sampled points" Style="{StaticResource GroupboxStyle}" FontFamily="{StaticResource LatoThin}" Foreground="{StaticResource TercoTextBrush}">
    <d3:Chart BottomTitle="Time" LeftTitle="voltage" Margin="-10" Style="{DynamicResource ChartStyle}">
        <d3:LineGraph x:Name="linegraph" Description="Simple linegraph" Stroke="Blue" StrokeThickness="2" Margin="-19,0,0,-23"/>
    </d3:Chart>
</GroupBox>

结果是线条本身伸出图形网格。如下图所示：我一直坐在这里试图修改图表的样式而没有运气。有人有这个问题吗？我使用交互式数据显示的原因是它使用起来非常简单。只需要两个阵列即可完成。如果您有任何更好的建议是免费的，我很乐意了解它。但不是Oxyplot。我无法使其发挥作用

您的LineGraph XAML标记的保证金正在改变这一行。

保证金指定为：

<object Margin="left,top,right,bottom"/>

因此-19,0,0的边距，-23指定向左移动19个单位并向下移动23个单位的xaml元素。这就是你所看到的。

变化：

<d3:LineGraph x:Name="linegraph" Margin="-19,0,0,-23" Description="Simple linegraph" Stroke="Blue" StrokeThickness="2" />

要：

<d3:LineGraph x:Name="linegraph" Margin="0" Description="Simple linegraph" Stroke="Blue" StrokeThickness="2" />
