12.4.1轴图元的轴线属性
在12.1绘图基本流程 中，我们介绍了设定轴线的颜色、风格、粗度等的例子，这些都属于轴图元的外观属性；此外，还可以设定坐标轴的箭头样式，如下面的例子：
|
|
A |
|
1 |
=canvas() |
|
2 |
=demo.query("select * from GYMSCORE order by NAME") |
|
3 |
=A1.plot("BackGround") |
|
4 |
=A1.plot("EnumAxis","name":"x","axisColor":-16737895,"axisLineWeight":2,"axisArrow":256) |
|
5 |
=A1.plot("NumericAxis","name":"y","location":2) |
|
6 |
=A1.plot("Column","axis1":"x","data1":A2.(EVENT+","+NAME),"axis2":"y","data2":A2.(SCORE)) |
|
7 |
=A1.plot("Legend","legendText":A2.id(NAME),"x":0.81,"y":0.2,"width": 0.18) |
|
8 |
=A1.draw@p(450,250) |
A2中获得绘图数据如下：
在画法中，A4个设定了横轴的线色、线粗和箭头等属性：
绘图结果如下：
可以看到，绘图参数修改后，下方的横轴样式发生了变化。
