我正在尝试使用crosstalk package,特别是filter_select()
函数,制作一个带有过滤到speci的选择框的交互式图表。
例如,我希望以下代码(在例如Flex仪表板中运行)生成一个图表,其中数据集中的国家/地区可以通过交互式输入进行过滤。
library(crosstalk)
library(ggplot2)
library(gapminder)
library(plotly)
sd <- SharedData$new(gapminder)
filter_select("country", "Country:", sd, ~ country)
g <- ggplot(sd, aes(year, lifeExp, color = country, group = country)) +
geom_line()
ggplotly(g)
虽然我得到了一个“国家:”选择输入,其中包含了国家/地区的名称,但结果图表(下面的屏幕截图)仍包含所有国家/地区,而不仅仅是我输入的国家/地区。
我尝试将图形显示为普通ggplot而不是调用ggplotly,并尝试在flexdashboard和R笔记本中运行它,但输入最终不会影响图形。如何使情节互动?
以下会话信息。顺便说一句,你需要使用sqly的dev版本(从GitHub安装)来使用带有串扰的情节。
