I found this stackoverflow post over here (Highlight/find data points in plotly scatter from the browser) in which they show how to create a search bar for a scatterplot in plotly.
I tried to run the code provided in this example:
library(plotly)
library(htmlwidgets)
library(htmltools)
pcaCars <- princomp(mtcars, cor = TRUE)
carsHC <- hclust(dist(pcaCars$scores), method = "ward.D2")
carsDf <- data.frame(pcaCars$scores, "cluster" = factor(carsClusters))
carsClusters <- cutree(carsHC, k = 3)
carsDf <- transform(carsDf, cluster_name = paste("Cluster", carsClusters))
p <- plot_ly(carsDf, x = ~Comp.1 , y = ~Comp.2, text = rownames(carsDf),
mode = "markers", color = ~cluster_name, marker = list(size = 11), type = 'scatter', mode = 'markers')
p <- htmlwidgets::appendContent(p, htmltools::tags$input(id='inputText', value='Merc', ''), htmltools::tags$button(id='buttonSearch', 'Search'))
p <- htmlwidgets::appendContent(p, htmltools::tags$script(HTML(
'document.getElementById("buttonSearch").addEventListener("click", function()
{
var i = 0;
var j = 0;
var found = [];
var myDiv = document.getElementsByClassName("js-plotly-plot")[0]
var data = JSON.parse(document.querySelectorAll("script[type=\'application/json\']")[0].innerHTML);
for (i = 0 ;i < data.x.data.length; i += 1) {
for (j = 0; j < data.x.data[i].text.length; j += 1) {
if (data.x.data[i].text[j].indexOf(document.getElementById("inputText").value) !== -1) {
found.push({curveNumber: i, pointNumber: j});
}
}
}
Plotly.Fx.hover(myDiv, found);
}
);')))
htmlwidgets::saveWidget(p, paste('pca', ".html", sep=""))
p
The code seems to run, but I do not see a search bar:
Can someone please show me what I am doing wrong and how I can fix this problem?
Thanks!
