第一步...找到您喜欢的系统字体(使用该功能listfonts
查看可用字体)或安装与xkcd的手写样式匹配的字体。我在博客文章中提到的用户ch00f 找到了一种“ Humor Sans” TrueType字体,并将其用于后续示例。
如我所见,通常需要三个不同的修改后的图形对象来制作此类图形:axis对象,line对象和text对象。您可能还希望使用一个注释对象使事情变得更容易,但是我现在暂时不予说,因为它可能比上述三个对象更难以实现。
我创建了包装函数,该包装函数创建了三个对象,它们覆盖了某些属性设置,使它们更加类似于xkcd。一个局限性是它们生成的新图形在某些情况下(例如,调整轴大小时在文本对象上的边界框)不会更新,但是可以通过更完整的面向对象的实现来解决,其中涉及从句柄继承class,使用事件和侦听器等。现在,这是我更简单的实现:
