我正在尝试绘制一个堆积的条形图，但我遗漏了一些东西。我有以下数据表示例：

Summary
1: Avg
2: WAvg
3: Max
我使用了熔化函数将数据表从宽转换为长：
d <- grep("hdisk", names(DT), value = T)
DT_mdf <- melt(DT,
id.vars="Summary",
measure.vars=d,
variable.name="hdisks",
value.name="percentage")
得到了这个：
Summary hdisks percentage
1: Avg hdisk86 0
2: WAvg hdisk86 0
3: Max hdisk86 0
4: Avg hdisk88 0
5: WAvg hdisk88 0
---
446: WAvg hdisk148 0
447: Max hdisk148 0
448: Avg hdisk149 0
449: WAvg hdisk149 0
450: Max hdisk149 0
然后我尝试绘制堆积的条形图并保存到png文件：
# Plot line graphics...
g1 <- ggplot(DT_mdf, aes(x=hdisks, y=percentage, fill=Summary)) +
geom_bar(stat = "identity") +
theme_excel() +
scale_color_excel() +
scale_fill_excel()
# Saving in png format
png("CPU_ALL_g1.png", width=16*ppi, height=9*ppi, res=ppi)
plot(g1)
dev.off()
我收到以下错误消息：
Saving 7 x 7 in image
Don't know how to automatically pick scale for object of type list. Defaulting to continuous
Error in pmin(y, 0) : object 'y' not found
Calls: ggsave ... transform -> transform.data.frame -> eval -> eval -> pmin
Execution halted
我是否有太多元素可以在单个图表中绘图？或其他什么？
这里是长格式的数据表样本：
