我有一個我想在溜冰場上繪制的曲棍球射擊位置的示例數據集( example_data
)。
structure(list(game_date = structure(c(17674, 17674, 17674, 17674,
17674), class = "Date"), event_team = c("WSH", "WSH", "T.B",
"T.B", "T.B"), event_description = c("WSH #8 OVECHKIN(12), Slap, Off. Zone, 53 ft.Assists: #92 KUZNETSOV(13); #43 WILSON(8) Expected Goal Prob: 1.6%",
"WSH ONGOAL - #92 KUZNETSOV, Wrist, Off. Zone, 13 ft. Expected Goal Prob: 50.4%",
"T.B ONGOAL - #17 KILLORN, Backhand, Off. Zone, 18 ft. Expected Goal Prob: 4.5%",
"T.B ONGOAL - #17 KILLORN, Wrist, Off. Zone, 23 ft. Expected Goal Prob: 4.6%",
"T.B ONGOAL - #27 MCDONAGH, Slap, Off. Zone, 57 ft. Expected Goal Prob: 1.2%"
), event_type = c(1, 0, 0, 0, 0), home_team = c("T.B", "T.B",
"T.B", "T.B", "T.B"), away_team = c("WSH", "WSH", "WSH", "WSH",
"WSH"), coords_x = c(-42, -80.3, 71, 67, 34), coords_y = c(-21,
12, -3, 9, 19)), class = c("tbl_df", "tbl", "data.frame"), row.names = c(NA,
-5L))
我成功地將溜冰場和我先前問題的答案結合在一起。 現在,我想嵌入兩個徽標(主隊/離隊徽標),並且我嘗試了此代碼,但無濟於事...
example_data %>%
plot_ly(x = ~coords_x, y=~coords_y,
text= ~event_description) %>%
add_markers(size = ~event_type,
sizes = c(150, 700),
alpha = 0.75,
color = ~factor(event_team),
colors = c("black", "slategrey")
) %>%
layout(
xaxis = list(range = c(-100,100)),
yaxis = list(range = c(-45,45)),
images= list(
list(
source= "https://i.imgur.com/Y2kOUX5.png",
xref= "paper",
yref= "paper",
x= 0,
y= 1,
sizex= 1,
sizey= 1,
opacity= 0.8,
layer = "below"),
list(
source = "http://www.capsinfo.com/images/NHL_Team_Logos/NHL_Ducks_Primary.png"
)
)
)
我究竟做錯了什么? 我想我需要在列表中指定xref
, yref
等,但是我不知道這些參數是什么意思
我認為您的第二張圖片可能有問題(太大,太小?)。 例如,使用網絡上的另一張圖片(在此處拍攝https://community.plot.ly/t/plotly-unable-to-embed-a-logo-or-background-image-in-plotly/2100/18 )作為第二個徽標,當您設置正確的參數時,您會看到第二個徽標出現。
example_data %>%
plot_ly(x = ~coords_x, y=~coords_y,
text= ~event_description) %>%
add_markers(size = ~event_type,
sizes = c(150, 700),
alpha = 0.75,
color = ~factor(event_team),
colors = c("black", "slategrey")
) %>%
layout(
xaxis = list(range = c(-100,100)),
yaxis = list(range = c(-45,45)),
images= list(
list(
source= "https://i.imgur.com/Y2kOUX5.png",
xref= "paper",
yref= "paper",
x= 0,
y= 1,
sizex= 1,
sizey= 1,
opacity= 0.8,
layer = "below"),
list(
source = "https://images.contentful.com/w3cthbuv8rf8/1g2AFv1q32mcceWaSK6CCS/7e8ae1f1a9266a044aa1c7988612b985/2008-the-dark-knight-version-of-the-symbol-is-largely-unchanged-from-the-original.png",
xref = "x",
yref = "y",
x = 50,
y = -20,
sizex = 20,
sizey = 20,
sizing = "stretch",
opacity = 0.5
)
)
)
現在,在您的問題中,您不必說要放在哪里。 要放置徽標,您可以使用兩個不同的參考(紙或x / y坐標)。
