One of the challenges I am facing involves manipulating multiple scatter plots created with highcharts. I have a list of checkboxes, each labeled to correspond with legend identifiers in the highcharts. My goal is to create a dynamic functionality so that when I check or uncheck a box, it will make the corresponding plot appear or disappear. How can I achieve this interactivity?
If you want to enable the desired functionality, you must change the Series.showInLegend flag by using the Series.update() method whenever a onchange event occurs on the checkbox. Additionally, remember to call the setVisible() function on that series to toggle its visibility on the plot. Below is an example code snippet demonstrating how this can be achieved:
Start by defining checkboxes as follows:
<input id="series1" type="checkbox" checked>Installation<br/>
<input id="series2" type="checkbox" checked>Manufacturing<br/>
<input id="series3"type="checkbox" checked>Sales and Distribution<br/>
Then iterate through each of these checkboxes and attach an onchange event handler. Within this function, update the corresponding series' showInLegend property based on the presence of the legendItem in the series object. See the code snippet below for more clarity:
var checkboxes = ['series1', 'series2', 'series3']
checkboxes.forEach((elem, i) => {
var checkbox = document.getElementById(elem)
checkbox.onchange = function() {
chart.series[i].update({
showInLegend: chart.series[i].legendItem ? false : true
})
chart.series[i].setVisible()
}
})
