我在plotly
创建条形图,y轴代表0-1内的百分比或份额。 y轴显示为0.05而不是5.0%。
有没有办法将y轴刻度标签显示为%##
?
我尝试使用tickformat = "%"
,但似乎无法正常使用。

您可以使用plotly
:
layout
中执行此操作
p <- p %>%
layout(yaxis = list(tickformat = "%"))
或者,如果您只想添加%
并且不重新格式化数字,那么:
p <- p %>%
layout(yaxis = list(ticksuffix = "%"))
这是一个示例,显示如何根据需要编辑y轴刻度。 (比如乘以数字并添加后缀等)
我有这段代码和下图:
p <- plot_ly(z = eegmean$value,
x = eegmean$xproj, y= eegmean$yproj, type = "contour") %>%
layout(yaxis = list(range = c(0, 1)))
然后我修改如下,这给了我想要的输出:
g <- plot_ly(z = eegmean$value,
x = eegmean$xproj, y= eegmean$yproj*100, type = "contour") %>%
layout(yaxis = list(range = c(0, 100)))%>%
layout(yaxis = list(ticksuffix = "%"))
eegmean <-
structure(list(xproj = c(-4.36892281283989, 4.35956894475236,

plotly
documentation会将我们引导至this页面,其中包含可用格式选项的完整列表。
在这种情况下,格式化5%
,tickformat='%'
等百分比就足够了。如果你想显示小数点,那么像'.n%'
这样的东西就可以了(用小数点后面的数字替换n)。
上面引用的github页面包含更多格式化选项。干杯!
