描述
Brief description of the problem:
Adding some lines and labels using the ggQC library causes a hard fail.
This code works with ggplotly:
min_date = as.Date(min(lots_df_filtered()$DATE))
max_date = as.Date(max(lots_df_filtered()$DATE))
if (!is.na(min_date)) {
num_days = length(seq(from = min_date, to = max_date, by = 'day')) - 1
date_breaks <- if(num_days <= 31) 'day' else 'week'
XmR_Plot <-
ggplot(lots_df_filtered(), aes(x = as.Date(DATE), y = YRS_YIELD)) +
geom_point(alpha = .5) + geom_line() +
labs(title=paste0(input$mfg_step_name, ' Lot Yield Control Chart')) +
scale_x_date(date_breaks=date_breaks) +
theme_ipsum_ps() +
theme(axis.text.x = element_text(angle = 60, vjust = 0.5, hjust=1),
axis.title.x=element_blank())
output$lot_time_series <- renderPlotly(ggplotly(XmR_Plot))
}`
Produces a nice chart as so:

The following code results in an error (alpha must be of length 1 or the same length as x):
min_date = as.Date(min(lots_df_filtered()$DATE))
max_date = as.Date(max(lots_df_filtered()$DATE))
if (!is.na(min_date)) {
num_days = length(seq(from = min_date, to = max_date, by = 'day')) - 1
date_breaks <- if(num_days <= 31) 'day' else 'week'
XmR_Plot <-
ggplot(lots_df_filtered(), aes(x = as.Date(DATE), y = YRS_YIELD)) +
geom_point(alpha = .5) + geom_line() +
stat_QC(method = "XmR",
auto.label = T,
label.digits = 2,
show.1n2.sigma = T
) +
labs(title=paste0(input$mfg_step_name, ' Lot Yield Control Chart')) +
scale_x_date(date_breaks=date_breaks) +
theme_ipsum_ps() +
theme(axis.text.x = element_text(angle = 60, vjust = 0.5, hjust=1),
axis.title.x=element_blank())
output$lot_time_series <- renderPlotly(ggplotly(XmR_Plot))
}
Here is what the ggplot looks like when I do not use ggplotly and do use ggCC:

Could this be related to the ggplotly argument layerData? Any help is appreciated.
thx

调研方向
首先运行提供的 R 复现代码,使用 ggplotly、ggplot2 和 ggQC,并将正常工作的图与使用 stat_QC() 的版本进行比较。调查报告的“alpha must be of length 1 or the same length as x”失败,并确认控制图图层能够通过 ggplotly 进行渲染,而不会发生硬错误。
