c# - C#图表，如何使文本不太像素化且没有边框？

Question

我正在使用 .NET 库来制作图表。我遇到的问题是 XY 轴的标签/标题非常像素化，它们似乎有一个黑色边框，我不知道如何删除。

另一个问题是，在图表上，有黑色轴从图表到黑色的标签，我不知道如何将它们设置为灰色。

我还为所有标签使用了一种名为 Inter 的字体，我不认为使用该字体会使标签有黑色边框。

谢谢您的帮助！

代码：

PrivateFontCollection pfc = new PrivateFontCollection();
int fontLength = RestocksDiscordBot.Properties.Resources.Inter_Bold.Length;
byte[] fontdata = RestocksDiscordBot.Properties.Resources.Inter_Bold;
System.IntPtr data = Marshal.AllocCoTaskMem(fontLength);
Marshal.Copy(fontdata, 0, data, fontLength);
pfc.AddMemoryFont(data, fontLength);
