legend.position = 'none') 绘制分组柱状图,默认是堆叠柱状图,即position=‘stack’ ggplot(data,aes(x=Experiment,y=Value, fill=Type))+ #根据不同Type填充颜色 geom_bar(stat = 'identity')+ labs(x=NULL)+ theme_bw(base_size = 18)+ theme(axis.text = element_text(colour = 'black')) 在柱状图...
本例在一个Stack组件中添加一个Text子组件,同时给Text组件添加position属性和markAnchor属性。Text组件会先采用position的坐标系,以Stack组件左上角为原点,移动到(50,50)的位置,再以(50,50)为坐标原点,采用markAnchor的坐标系移动到(25,25)的位置,代码如下: ...

1.Stack Stack 这个是Flutter中布局用到的组件,可以叠加的现实View. alignment : 指的是子Widget的对其方式,默认情况是以左上角为开始点 ,这个属性是最难理解的,它区分为使用了Positioned和未使用Positioned定义两种情况,没有使用Positioned情况还是比较好理解的.fit :
position_identity()函数的意思是不调整位置,所以对x,每种净度的bar都是从y=0开始的,而不是像stack似的一个堆在另一个的上面,所以identity图中每个净度bar是有覆盖的。仔细观察纵坐标,两者是不一样的。identity这种选项更适合2D的geom(比如散点图,x和y都从从原始数据集中得到,展示原始的数据点)...
