MS图表控件：格式化轴标签

Question

我对格式化MS ASP.NET图表控件的轴标签有疑问。在深入探讨我的问题之前，请看看这个截图。

正如你在截图中看到，轴标签是很难读，似乎加粗。现在，我的问题是：

• 哪些默认图表属性导致轴标签看起来不像Arial 11px常规，即粗体和紧密字符？
• 轴标签的外观如何更易于阅读和清理，即规则的字体重量和字符之间的分隔度？

该负责代码：

public Chart GetChart(ChartData chartDataData, IChartSettings settings) 
{ 
    var chart = new Chart 
    { 
     BackColor = Color.Transparent, 
     Height = settings.Height, 
     Palette = ChartColorPalette.None, 
     PaletteCustomColors = settings.PaletterCustomColors.ToArray(), 
     Width = settings.Width 
    }; 
    if (settings.ShowLegend) 
    { 
     chart.Legends.Add("Legend").Alignment = StringAlignment.Center; 
    } 
    AddChartArea(chart); 

    foreach (var seriesData in chartDataData.Series) 
    { 
     AddSeries(chart, seriesData, settings.ChartType); 
    } 

    chart.AlignDataPointsByAxisLabel(); 
    return chart; 
} 

private void AddChartArea(Chart chart) 
{ 
    var area = new ChartArea(); 
    area.AxisX.LabelStyle.Angle = -45; 
    area.AxisX.MajorGrid.LineColor = Color.Transparent; 
    chart.ChartAreas.Add(area); 
    area.AxisX.LabelStyle.Font = area.AxisY.LabelStyle.Font = new Font("Arial", 11, GraphicsUnit.Pixel); 
} 

private void AddSeries(Chart chart, SeriesData data, SeriesChartType chartType) 
{ 
    var series = new Series 
    { 
     ChartType = chartType, 
     Name = data.Name, 
     ToolTip = data.Name, 
     Url = data.Url 
    }; 

    foreach (var pointData in data.Points) 
    { 
     AddPoint(series, pointData.XValue, pointData.YValue); 
    } 
    chart.Series.Add(series); 
} 

private void AddPoint(Series series, string xValue, float yValue) 
{ 
    var point = new DataPoint 
    { 
     AxisLabel = xValue 
    }; 
    point.SetValueXY(xValue, yValue); 
    series.Points.Add(point); 
} 

，其中用于设置代码对象是：

public static ChartSettings TaskSummary = new ChartSettings 
{ 
    ChartType = SeriesChartType.StackedColumn, 
    Height = Unit.Pixel(300), 
    Width = Unit.Pixel(450), 
    PaletterCustomColors = new[] 
    { 
     Color.FromArgb(191, 214, 151), 
     Color.FromArgb(249, 255, 149), 
     Color.FromArgb(191, 79, 75), 
     Color.Green 
    }, 
    ShowLegend = true 
}; 

感谢您的帮助。

如果将图表的BackColor设置为Color.Transparent，则需要设置AntiAliasing="Graphics"。
