Layer in Leaflet JS doesnt show again when check the control layer

I use the leaflet control layer to show up and remove the layer when I didn't wanna show the layer. when I uncheck my control layer it worked properly. the layer can disappear, but when I check again the control layer, the layer didn't show again. but there is no error in the console .
var pieChartGroup = L.featureGroup().addTo(map);
vals.forEach(val => {
var pictures = L.marker(val.location, {
icon: L.divIcon({
className: 'leaflet-echart-icon',
iconSize: [160, 160],
html: '<div id="marker' + val.id + '" style="width: 160px; height: 160px; position: relative; background-color: transparent;"></div>'
})
}).addTo(pieChartGroup);
// Based on the prepared dom, initialize the echarts instance
var myChart = echarts.init(document.getElementById('marker' + val.id));
// Specify chart configuration items and data

Google Scatter Chart multiple tooltips overlapping each other

I am using google charts and showing 3 tooltips by default when chart is loaded for that i have used
tooltip: { trigger: 'selection' },
aggregationTarget: 'none',
selectionMode: 'multiple'
Every thing is working fine but when the points get very close to each other like (1,1) and (1,1.5) the tool tips comes over each other please see this image. Is there any option or a way to overcome this.

there are no options you can set to avoid overlap...
a possible solution would be to use the explorer option to pan and zoom
explorer: {
actions: ['dragToZoom', 'rightClickToReset']
}
see following working snippet, when the chart loads,
use the mouse to draw a square around the two points on the lower left,
once zoomed, both tooltips are displayed fully...

How can I show only one x-axis in synchronous chart highchart

function syncExtremes(e) {

Highcharts.each(Highcharts.charts, function (chart) {

Any help will be appreciated

You can hide unwanted x axes using visible property:
xAxis: {
visible: i === 2,
(...)
},

Google chart - role: annotation in candlestick bar [duplicate]

i'm trying to use Google Chart API for building an Waterfall chart. I noticed that Candlestick/Waterfall charts are not supporting the annotations.
See this jsfiddle sample
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Category');
data.addColumn('number', 'MinimumLevel');
data.addColumn('number', 'MinimumLevel1');
data.addColumn('number', 'MaximumLevel');
data.addColumn('number', 'MaximumLevel1');
data.addColumn({type: 'number', role: 'tooltip'});
data.addColumn({type: 'string', role: 'style'});
data.addColumn({type: 'number', role: 'annotation'});
data.addRow(['Category 1', 0 , 0, 5, 5, 5,'gray',5]);
data.addRow(['Category 2', 5 , 5, 10, 10, 10,'red',10]);
data.addRow(['Category 3', 10 , 10, 15, 15, 15,'blue',15]);
data.addRow(['Category 4', 15 , 15, 10, 10, 10,'yellow',10]);
data.addRow(['Category 5', 10 , 10, 5, 5, 5,'gray',5]);
var options = {
legend: 'none',
bar: { groupWidth: '60%' } // Remove space between bars.
};
var chart = new google.visualization.CandlestickChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
I would like to put the value of the 5th column at the top of every candlestick.
It should look like this :
Is there a way to do this?
Thanks

I add annotations to candlestick charts by adding annotations to a hidden scatter plot. You can set exactly where you want the annotations to sit by changing the plot.
google.charts.load('current', { 'packages': ['corechart'] });
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Low');
data.addColumn('number', 'Open');
data.addColumn('number', 'Close');
data.addColumn('number', 'High');
data.addColumn('number'); //scatter plot for annotations
data.addColumn({ type: 'string', role: 'annotation' }); // annotation role col.
data.addColumn({ type: 'string', role: 'annotationText' }); // annotationText col.
var high, low, open, close = 160;
for (var i = 0; i < 10; i++) {
open = close;
close += ~~(Math.random() * 10) * Math.pow(-1, ~~(Math.random() * 2));
high = Math.max(open, close) + ~~(Math.random() * 10);
low = Math.min(open, close) - ~~(Math.random() * 10);
annotation = '$' + close;
annotation_text = 'Close price: $' + close;
data.addRow([new Date(2014, 0, i + 1), low, open, close, high, high, annotation, annotation_text]);
}
var view = new google.visualization.DataView(data);
var chart = new google.visualization.ComboChart(document.querySelector('#chart_div'));
chart.draw(view, {
height: 400,
width: 600,
explorer: {},
chartArea: {
left: '7%',
width: '70%'
},
series: {
0: {
color: 'black',
type: 'candlesticks',
},
1: {
type: 'scatter',
pointSize: 0,
targetAxisIndex: 0,
},
},
candlestick: {
color: '#a52714',
fallingColor: { strokeWidth: 0, fill: '#a52714' }, // red
risingColor: { strokeWidth: 0, fill: '#0f9d58' } // green
},

Not able to click on label in google chart api

I am new to javascript and i am using google chart api for creating charts. i wanted to click on left side label that shows in below image. so, my question is that can we click on left side label?
give me some idea for this. if it is possible then help me.
function drawStackedChart(reqCategoryId,fcategoryName)

for(var i=0;i<complaintStatus.length;i++)
{
data.addColumn('number',complaintStatus[i].statusName);
data.addColumn({type: 'number',role: 'scope'});
}
data.addRows(jsonData.length);
var maxVal=jsonData[0].totalCountComplaint;
for(i=0;i<jsonData.length;i++)
{
// trying to create hyperlink
data.setCell(i,0,'+jsonData[i].categoryName+');
data.setCell(i,1,jsonData[i].categoryId);
for(j=0; j< jsonData[i].complaintStatus.length; j++)
{
data.setCell(i,parseInt(jsonData[i].complaintStatus[j].statusId)*2, jsonData[i].complaintStatus[j].countComplaint);

var chart = new google.visualization.BarChart(document.getElementById('donutchart'));
chart.draw(data, options);
new google.visualization.events.addListener(chart, 'select', selectionHandler);
function selectionHandler() {
// code for selection handler
}

you can use the targetID of the 'click' event to find the label that was clicked
when a y-axis label is clicked, the targetID will hold a value similar to the following...
vAxis#0#label#0
you can use the string method split, to find the label value in the data
selection = e.targetID.split('#');
when the first value = vAxis, this means a y-axis label was clicked
if (selection[0].indexOf('vAxis') > -1) {
the first integer refers to the y-axis, in this example, there is only one
the second integer refers to the row in the data
to get the value clicked...
data.getValue(rowIndex, colIndex);
e.g.
data.getValue(parseInt(selection[selection.length - 1]), parseInt(selection[1])));
see following working snippet...
google.charts.load('current', {
callback: drawChart,
packages:['corechart']
});
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Element', 'Density', { role: 'style' } ],
['Copper', 8.94, '#b87333'],
['Silver', 10.49, 'silver'],
['Gold', 19.30, 'gold'],
['Platinum', 21.45, 'color: #e5e4e2']
]);
var options = {
title: 'Density of Precious Metals, in g/cm^3',
width: 600,
height: 400,
bar: {groupWidth: '95%'},
legend: { position: 'none' },
};
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
google.visualization.events.addListener(chart, 'click', function(e) {
var selection;
if (e.targetID) {
selection = e.targetID.split('#');
if (selection[0].indexOf('vAxis') > -1) {
console.log('label clicked = ' + data.getValue(parseInt(selection[selection.length - 1]), parseInt(selection[1])));
}
}
});
chart.draw(data, options);
