myfactor<-reorder(x,X,FUN=。。)其中,x参数是一个离散型的向量,X是与x等长的一个变量,按照fun(X)对x进行排序即可 8、stat参数 加上stat=“identity”的参数,类似于weight的功能 ggplot(data=mtcars,mapping=aes(x=factor(cyl),y=wt))+geom_bar(color="red",fill="blue",alpha=0.5,stat="identity")...
接下来,用ggplot()+geom_bar()画出基本的条形图。 ?...这里面,使用reorder()函数,使得按照Difference取值大小,条形图进行排序。同时,在这一步设置对每个条形加黑色边框,调整条形宽度,并使得中间留有空隙。 ?...最后,我们修改图例的颜色、字体,并在条形图两侧加入标签文字,就可以得到最终的效果了。 ? ? 想要图...

利用ggplot实现的思路也是先构建bar(geom_bar),然后将坐标系转为极坐标系(coord_polar) 下边是官方文档给出的例子: # A coxcomb plot = bar chart + polar coordinates cxc <- ggplot(mtcars, aes(x = factor(cyl))) + geom_bar(width = 1, colour = "black") ...
Bar plots in ggplot2 with the geom_bar and geom_col functions. Flip the axes, add labels to the bars, reorder the bars and customize the colors and the legend
Basic bar plots # Basic bar plotsggplot(df, aes(x = rowname, y = mpg)) + geom_col() + rotate_x_text(angle =45) # Reorder row names by mpg valuesggplot(df, aes(x = reorder(rowname, mpg), y = mpg)) + geom_col() + rotate_x_text(angle =45) ...
The trick is the following: - input data frame has 2 columns: the group names (`group` here) and its value (`value` here) - build a stacked barchart with one bar only using the `geom_bar()` function. - Make it circular with `coord_polar()` The result is far from...
