堆叠面积图的一些问题 - pgfplot

Question

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：

Answer 1

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。
2. 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。
3. 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。
