如何在ZedGraph中设置y2、y7等非主Y轴的字体与字号

解决方案 #

你调用AddYAxis方法时返回的索引值，可直接用于定位GraphPane的YAxisList集合中对应的额外Y轴实例，分别设置轴标题和刻度标签的字体属性即可，修改后的代码参考如下：

if (plotValue.Keys.Contains("DD_CurrentPrice"))
{
    y2 = graphArea.AddYAxis("DD - Price");
    // 设置y2轴标题字体
    graphArea.YAxisList[y2].Title.FontSpec = new FontSpec("Cambria", 10.0f, Color.Black, false, false, false);
    // 设置y2轴刻度数值字体
    graphArea.YAxisList[y2].Scale.FontSpec = new FontSpec("Cambria", 9.0f, Color.Black, false, false, false);
    
    curve = new LineItem("DD - Current Price", null, plotValue["DD_CurrentPrice"], Color.FromArgb(255, 198, 001), SymbolType.None) { YAxisIndex = y2 };
    curve.Label.FontSpec = new FontSpec("Cambria", 10.0f, Color.Black, false, false, false);
    graphArea.CurveList.Add(curve);
}

if (plotValue.Keys.Contains("PD_MarkdownPrice") || plotValue.Keys.Contains("PD_CurrentPrice"))
{
    y7 = graphArea.AddYAxis("PD - Price");
    // 设置y7轴标题字体
    graphArea.YAxisList[y7].Title.FontSpec = new FontSpec("Cambria", 10.0f, Color.Black, false, false, false);
    // 设置y7轴刻度数值字体
    graphArea.YAxisList[y7].Scale.FontSpec = new FontSpec("Cambria", 9.0f, Color.Black, false, false, false);
    
    if (plotValue.Keys.Contains("PD_MarkdownPrice"))
    {
        curve = new LineItem("PD - Markdown Price", null, plotValue["PD_MarkdownPrice"], Color.FromArgb(045, 186, 030), SymbolType.None) { YAxisIndex = y7 };
        curve.Label.FontSpec = new FontSpec("Cambria", 10.0f, Color.Black, false, false, false);
        graphArea.CurveList.Add(curve);
    }
    if (plotValue.Keys.Contains("PD_CurrentPrice"))
    {
        curve = new LineItem("PD - Current Price", null, plotValue["PD_CurrentPrice"], Color.FromArgb(011, 138, 000), SymbolType.None) { YAxisIndex = y7 };
        curve.Label.FontSpec = new FontSpec("Cambria", 10.0f, Color.Black, false, false, false);
        graphArea.CurveList.Add(curve);
    }
}

其中Title.FontSpec对应轴标题的字体样式，Scale.FontSpec对应轴刻度数值的字体样式，可根据需求调整字号、颜色等参数。
