e_on on tile and secondary plot

[antoine4ucsd]

Hello
I am struggling with e_on. My goal is to have a secondary graph to appear on the side of the primary graph when clicking on the tile corresponding to the 'yes'
for example this dataframe

df=data.frame(
                tx_o2.factor = c("yes", "no", "yes", "no", "yes", "no"),
                value = c(5, 3, 4, 2, 6, 1)
        )

I can generate the main pie chart

df%>%
        dplyr::summarise(n = n(), .by = tx_o2.factor) %>%
        dplyr::mutate(
                N = sum(n),
                pct = round(n / N, 2),
                lab_pct = str_c(round(pct * 100), "%"),
                lab_n = str_c(n, " / ", N)
        ) %>%
        e_charts(tx_o2.factor) %>%
        e_pie(pct, radius = c("40%", "70%")) %>%
        e_labels(formatter = htmlwidgets::JS("
        function(params) {
          return params.name + ': ' + 100 * params.value + '%'
        }")) %>%
        e_tooltip(trigger = "item", formatter = htmlwidgets::JS("
        function(params) {
          return '<strong>' + params.name + '</strong><br /> ' + 100 * params.value + '%'
        }"), backgroundColor = "rgba(255,255,255,0.7)") %>%
        e_on("click", htmlwidgets::JS("
        function(params) {
          console.log('Clicked on: ', params.name); // Debugging line
          Shiny.setInputValue('clickedSegment', params.name);
        }"))

and my secondary graph could be for example

df%>%
      filter(tx_o2.factor == "yes") %>%
     e_charts(tx_o2.factor) %>%
     e_bar(value)

but only appears when I click on the yes tile of the pie chart.... ?

and ALL in one (not working at all)

reactive_db <- reactive({
        data.frame(
                tx_o2.factor = c("yes", "no", "yes", "no", "yes", "no"),
                value = c(5, 3, 4, 2, 6, 1)
        )
})

                        echarts4rOutput("mainChart"),
                        uiOutput("secondaryChartUI")
                )
        )
)

server <- function(input, output, session) {
        output$mainChart <- renderEcharts4r({
                reactive_db() %>%

                        dplyr::mutate(

                                pct = round(n / N, 2),
                                lab_pct = str_c(round(pct * 100), "%"),
                                lab_n = str_c(n, " / ", N)
                        ) %>%
                        e_charts(tx_o2.factor) %>%

        }"), backgroundColor = "rgba(255,255,255,0.7)") %>%
                        e_toolbox_feature(feature = c("saveAsImage")) %>%
                        e_on("click", htmlwidgets::JS("

          Shiny.setInputValue('clickedSegment', params.name);
        }"))
        })
        observeEvent(input$clickedSegment, {

                }
        })
}

does that make sense? any suggestion?

Use name and refer to it in e_on, no need to wrap the handler in htmlwidgets::JS

df%>%
        dplyr::summarise(n = n(), .by = tx_o2.factor) %>%
        dplyr::mutate(
                N = sum(n),
                pct = round(n / N, 2),
                lab_pct = str_c(round(pct * 100), "%"),
                lab_n = str_c(n, " / ", N)
        ) %>%
        e_charts(tx_o2.factor) %>%
        e_pie(pct, radius = c("40%", "70%"), name = "pie") %>% # add name
        e_labels(formatter = htmlwidgets::JS("
        function(params) {
          return params.name + ': ' + 100 * params.value + '%'
        }")) %>%
        e_tooltip(trigger = "item", formatter = htmlwidgets::JS("
        function(params) {
          return '<strong>' + params.name + '</strong><br /> ' + 100 * params.value + '%'
        }"), backgroundColor = "rgba(255,255,255,0.7)") %>%

I removed the setInputValue in my response, you have to add it back in

trying now

really sorry.
anywhere close?

just tried the code below but nothing happen

df%>%
        dplyr::summarise(n = n(), .by = tx_o2.factor) %>%
        dplyr::mutate(
                N = sum(n),
                pct = round(n / N, 2),
                lab_pct = str_c(round(pct * 100), "%"),
                lab_n = str_c(n, " / ", N)
        ) %>%
        e_charts(tx_o2.factor) %>%
        e_pie(pct, radius = c("40%", "70%"), name = "myname") %>% # add name
        e_labels(formatter = htmlwidgets::JS("
        function(params) {
          return params.name + ': ' + 100 * params.value + '%'
        }")) %>%
        e_tooltip(trigger = "item", formatter = htmlwidgets::JS("
        function(params) {
          return '<strong>' + params.name + '</strong><br /> ' + 100 * params.value + '%'
        }"), backgroundColor = "rgba(255,255,255,0.7)") %>%
        e_on(list(seriesName = "myname"), # use name
             "function(params) {
          console.log('Clicked on: ', params);
          Shiny.setInputValue('clickedSegment', params.name);
        }")

I would like to see a secondary plot to appear based on the segment I click on.
in that case, If I click on 'yes', I would see

df%>%
      filter(tx_o2.factor == "yes") %>%
     e_charts(tx_o2.factor) %>%
     e_bar(value)

and if I click on no,

df%>%
      filter(tx_o2.factor == "yes") %>%
     e_charts(tx_o2.factor) %>%
     e_bar(value)

the final objective is to have it to run in a shiny app...
all suggestions are very welcome

[JohnCoene]

Did you check that params.name does exist?, params change from one callback to another.

[antoine4ucsd]

I thought params.name was coming from e_charts(tx_o2.factor)
my df can be reproduced as follow

reactive_df <- reactive({
data.frame(
tx_o2tor.factor = c("yes", "no", "yes", "no", "yes", "no"),
value = c(5, 3, 4, 2, 6, 1)
)
})

[antoine4ucsd]

I confirm params.name exists
with the following code,

df=        data.frame(
        tx_o2.factor = c("yes", "no", "yes", "no", "yes", "no"),
        value = c(5, 3, 4, 2, 6, 1)
)

df%>%
        dplyr::summarise(n = n(), .by = tx_o2.factor) %>%
        dplyr::mutate(
                N = sum(n),
                pct = round(n / N, 2),
                lab_pct = str_c(round(pct * 100), "%"),
                lab_n = str_c(n, " / ", N)
        ) %>%
        e_charts(tx_o2.factor) %>%
        e_pie(pct, radius = c("40%", "70%"), name = "pie") %>% # add name
        e_labels(formatter = htmlwidgets::JS("
        function(params) {
          return params.name + ': ' + 100 * params.value + '%'
        }")) %>%
        e_tooltip(trigger = "item", formatter = htmlwidgets::JS("
        function(params) {
          return '<strong>' + params.name + '</strong><br /> ' + 100 * params.value + '%'
        }"), backgroundColor = "rgba(255,255,255,0.7)") %>%
        e_on(list(seriesName = "pie"), # use name
             "function(params) {
          console.log('Clicked on: ', params);
          Shiny.setInputValue('clickedSegment', params.name);
        }")

so params.name corresponds to yes or no.
the objective is that when one click on yes, a bar plot show up beside the pie chart and a different bar plot appears when click on no.

I cannot run the code you shared.

sorry.

would you mind trying
