我們有一個可視化顯示代表 CPE 質量 KPI 的聚合資料。這里簡化了，只有 1 天：
在左側，我們看到兩類引數。SNR 和 RX，分為 AVG、MIN_AVG、MAX_AVG。
現在我想填充snr_min_avg_daandsnr_max_avg_ds和之間的區域rx_min_avgand rx_max_avg，但它不起作用。我試過：
df_snr_ds_ribbon = df_topo_cpe[, c("dt", "snr_min_avg_ds", "snr_max_avg_ds")]
df_snr_ds_ribbon[, Type:="Downstream"]
ggplot(df2plot, aes(x=dt, y=Value, color=Parameter, group=Parameter))
geom_line()
geom_ribbon(data=df_snr_ds_ribbon, aes(ymin=snr_min_avg_ds, ymax=snr_max_avg_ds))
facet_wrap(~Type)
theme_bw()
scale_color_manual(values=group.colors)
-->Error in FUN(X[[i]], ...) : object 'Parameter' not found
有人可以幫忙嗎？

uj5u.com熱心網友回復：
也許這就是你要找的？不幸的是，您的 MWE 無法重現，因為它缺少資料集df_topo_cpe。但是我試了一下，因為我猜這是您df2plot的寬格式資料，因此問題是您用于功能區的資料集缺少列Parameter，Value并且您指定為全域 aes。
要解決此問題，您可以簡單地將這些美學設定為geom_line圖層的區域。
group.colors <- c(
snr_avg_ds = "red3", snr_min_avg_ds = "red1", snr_max_avg_ds = "red1",
rx_avg = "royalblue4", rx_min_avg = "royalblue1", rx_max_avg = "royalblue1",
snr_avg_us = "royalblue1"
)
df_snr_ds_ribbon = df2plot[Parameter %in% c("dt", "snr_min_avg_ds", "snr_max_avg_ds"), ] |>
tidyr::pivot_wider(names_from = "Parameter", values_from = "Value")
ggplot(df2plot, aes(x = dt))
geom_line(aes(y = Value, color = Parameter, group = Parameter))
geom_ribbon(data=df_snr_ds_ribbon, aes(ymin=snr_min_avg_ds, ymax=snr_max_avg_ds), fill = "red1")
facet_wrap(~Type)
theme_bw()
scale_color_manual(values = group.colors)
