![堆叠面积图的一些问题 - pgfplot](https://linux22.com/image/328484/%E5%A0%86%E5%8F%A0%E9%9D%A2%E7%A7%AF%E5%9B%BE%E7%9A%84%E4%B8%80%E4%BA%9B%E9%97%AE%E9%A2%98%20-%20pgfplot.png)
我对堆叠面积图有三个问题。
1:我想让绘图更宽,以适合我的演示文稿。但如果我在 x 方向上缩放,字体(标签)也会缩放。如何避免这种情况?
2:我尝试过的所有方法都\sffamily
不起作用。可能是我没有找到正确的开关。我该怎么做?
3:我想更改xlabels
。绘图应从 2014 年开始,但标签应从 2015 年开始。没有标签的刻度应有 |。我尝试说明我想要什么xlabels

这是我迄今为止尝试过的:

答案1
- 问题是如何您缩放图表。如果您直接使用
width
和height
命令缩放轴,字体大小将不会改变。 - 这是一个非常常见的问题,并且已得到解答这里例如。简而言之,您只更改了“普通”字体,而没有更改“数学”字体。而且由于数字
tick
是在数学模式下打印的,因此您只获得了默认的数学字体。 - 在这里,您可以简单地使用键“手动”声明标签
xtick
并提供您想要显示的值。正如您在代码中看到的,您还可以使用“智能”版本。使用键,minor x tick num
您可以提供次要刻度数。
