R - y axis as time interval

[arak]

I'm building an R report to display time in y axis.

The R code I'm using is as follows:

library(ggplot2)


c1_graph <- ggplot(dataset, aes(workflow_code,Value, fill= Attribute))+
geom_col(width=0.4, position=position_dodge(width=0.5)) +
#scale_y_continuous(limits=c(min_value,max_value))+
 theme(axis.text.x=element_text( angle=90, hjust=1, vjust=0.5))+
 theme(axis.title.x=element_blank())+
        #scale_y_time(breaks = time_breaks)
# theme(axis.text.y=element_text(size=8))+
        scale_y_time(labels=function(1), strftime(1, '%H:%M:%S'))
theme(axis.title.y=element_blank())+
 theme(legend.position="bottom")+
 theme(legend.title=element_blank())
 c1_graph

My time appears a bit congested. How can I set time intervals?

Also, is it possible to get tooltips so that when I hover over the graph it would display the values?
And, how can I adjust the overall size of R report?

Thanks,

AR

You might be interested in c1_graph + coord_flip(...)

Otherwise, try ggsave() to save the graph in certain size (with certain DPI), and load that image. I'm not sure how that would work in PowerBI though.
