英文:
Highchart Tooltip in R
问题
我正在使用highchart绘制“初始肿瘤”与“复发肿瘤”的图表。我使用工具提示，以便在鼠标悬停时显示tumor_category的详细信息，例如：
初始肿瘤：
4个肿瘤
计数：16
复发肿瘤：
4个肿瘤
计数：18
我使用以下highchart代码：
highchart() %>%
hc_chart(type = "bubble") %>%
hc_add_series(
data = initial_tumors$count,
name = "Initial tumors",
type = "bubble",
color = "purple",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_add_series(
data = modified_recurring_tumors$count,
name = "Recurring tumors",
type = "spline",
color = "red",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_tooltip(
shared = FALSE,
formatter = JS(
"function() {
var tumorCategory;
if (this.series.name === 'Initial tumors' || this.series.name === 'Initial tumor categories') {
tumorCategory = this.point.y;
} else if (this.series.name === 'Recurring tumors' || this.series.name === 'Recurring tumor categories') {
tumorCategory = this.point.y;
}
var tooltip = '<b>' + this.series.name + '</b><br> : ' + tumorCategory + '<br>Count: ' + this.y;
return tooltip;
}"
)
) %>%
hc_title(text = "Initial vs Recurring Tumors")
但是当我将鼠标悬停在图表上时，它不显示tumor_category，而是显示计数。
如何更正它？
英文:
I Have two datasets (initial_tumors and modified_recurring_tumors).
dput:
initial_tumors:
structure(
list(
number = c(1L, 3L, 2L, 4L, 5L, 6L, 8L),
count = c(145L,
47L, 38L, 25L, 16L, 14L, 9L),
tumor_category = c(
"1 Tumor",
"3 Tumors",
"2 Tumors",
"4 Tumors",
"5 Tumors",
"6 Tumors",
"8 or more Tumors"
)
),
row.names = c(NA,-7L),
class = c("tbl_df", "tbl", "data.frame")
)
data2:
modified_recurring_tumors:
structure(
list(
recur = c(NA, 5L, 1L),
count = c(111L, 46L, 45L),
tumor_category = c("8 or more Tumors", "5 Tumors", "1 Tumor")
),
row.names = c(NA,-3L),
class = c("tbl_df", "tbl", "data.frame")
)
I am plotting a graph using highchart for Initial Tumors vs Recurrent Tumors. I am using tooltip so that when mouse is hovered it shows the tumor_category details such as:
Initial Tumors:
4 Tumors
Count:16
Recurrent Tumors:
4 Tumors
Count:18
Am using following highchart code:
highchart() %>%
hc_chart(type = "bubble") %>%
hc_add_series(
data = initial_tumors$count,
name = "Initial tumors",
type = "bubble",
color = "purple",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_add_series(
data = modified_recurring_tumors$count,
name = "Recurring tumors",
type = "spline",
color = "red",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_tooltip(
shared = FALSE,
formatter = JS(
"function() {
var tumorCategory;
if (this.series.name === 'Initial tumors' || this.series.name === 'Initial tumor categories') {
tumorCategory = this.point.y;
} else if (this.series.name === 'Recurring tumors' || this.series.name === 'Recurring tumor categories') {
tumorCategory = this.point.y;
}
var tooltip = '<b>' + this.series.name + '</b><br> : ' + tumorCategory + '<br>Count: ' + this.y;
return tooltip;
}"
)
) %>%
hc_title(text = "Initial vs Recurring Tumors")
But when I hover the mouse over the graph, it is not showing the tumor_category but is showing count.
How to correct it?

Sure, here is the translated code:
当您使用 `hc_add_series` 时，只传递了列值；如果您传递数据框，您可以访问其他列的数据。使用 `hcaes`，您可以定义 y 轴值（计数）。在格式化器中，您可以使用 `this.point.tumor_category` 访问类别，以及 `this.point.count` 访问计数。
library(tidyverse)
library(highcharter)
highchart() %>%
hc_chart(type = "bubble") %>%
hc_add_series(
data = initial_tumors,
hcaes(y = count),
name = "Initial tumors",
type = "bubble",
color = "purple",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_add_series(
data = modified_recurring_tumors,
hcaes(y = count),
name = "Recurring tumors",
type = "spline",
color = "red",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_tooltip(
shared = FALSE,
formatter = JS(
"function() {
var tooltip = '<b>' + this.series.name + '</b>' +
'<br>Tumor category: ' + this.point.tumor_category +
'<br>Count: ' + this.point.count;
return tooltip;
}"
)
) %>%
hc_title(text = "Initial vs Recurring Tumors")
Please note that I have translated the code portion as requested, excluding the code itself.
英文:
When you use hc_add_series you only passed in the column values; if you instead pass in the data.frame you can access other column data. Using hcaes you can define your y-axis value (count). In your formatter, you can use this.point.tumor_category to access the category, and this.point.count to access the count.
library(tidyverse)
library(highcharter)
highchart() %>%
hc_chart(type = "bubble") %>%
hc_add_series(
data = initial_tumors,
hcaes(y = count),
name = "Initial tumors",
type = "bubble",
color = "purple",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_add_series(
data = modified_recurring_tumors,
hcaes(y = count),
name = "Recurring tumors",
type = "spline",
color = "red",
dataLabels = list(enabled = TRUE, format = "{point.y}")
) %>%
hc_tooltip(
shared = FALSE,
formatter = JS(
"function() {
var tooltip = '<b>' + this.series.name + '</b>' +
'<br>Tumor category: ' + this.point.tumor_category +
'<br>Count: ' + this.point.count;
return tooltip;
}"
)
) %>%
hc_title(text = "Initial vs Recurring Tumors")
