我在 R 中创建了一个 plotly 图表,然后通过 htmlwidget 保存该图,以便可以在 slidify 中调用该图。我在两个论点中都使用了width
and ,以便在滑动幻灯片上拟合绘图,但是当将一些文本添加在一起时,最终结果总是会切掉图表的底部。height
layout
index.Rmd
如何在 slidify 中真正调整绘图图表的大小?
R脚本中的代码
## first slide
date <- seq(from = as.POSIXct("2015/4/1"),
to = as.POSIXct("2015/10/1"),
by = "month")
as.Date(date, "%Y/%m/%d")
set.seed(2016)
tot.prem <- runif(n = 7, min = 0, max = 1200)
pol.frce <- runif(n = 7, min = 0, max = 6000)
tot.data <- cbind(date, tot.prem, pol.frce)
tot.data <- data.frame(Date = as.POSIXct(date, format = "%Y/%m/%d"),
WP = tot.prem,
PIF = pol.frce)
m = list(
l = 50,
r = 50,
b = 100,
t = 100,
pad = 4
)
p1 <- tot.data %>%
subplot(plot_ly(x = date, y = tot.prem, type = "bar"),
plot_ly(x = date, y = pol.frce, type = "bar"), margin = 0.05) %>%
layout(showlegend = FALSE,
title = "Written Premium and PIF",
yaxis = list(title = "WP (in Millions)", showgrid = FALSE),
xaxis = list(title = "Date"),
yaxis2 = list(title = "Policy in Force", showgrid = FALSE),
xaxis2 = list(title = "Date"),
autosize = F, width = 600, height = 400, margin = m
)
p1
# saveWidget(dplot, 'plotlyex1.html')
htmlwidgets::saveWidget(as.widget(p1), "wp.html")
