Hide all series button in CanvasJS graph (javascript foreach usage)

The question related to CanvasJS, but probably any expert in pure javascript could help.
I need a button to hide/unhide all elements in canvasjs graph.
There is a working code that can hide element using array index:
chart.options.data[0].visible = !chart.options.data[0].visible;
I'm trying to go through array, but it doesn't work, obviously my code is wrong:
chart.options.data.forEach(visible = !visible);
How should I fix it?
The full code snippet is:
var chart = new CanvasJS.Chart("chartContainer",
{
title:{
text: "Test Button to Hide All Series"
},
legend: {
cursor: "pointer",
itemclick: function (e) {
//console.log("legend click: " + e.dataPointIndex);
//console.log(e);
if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
e.dataSeries.visible = false;
} else {
e.dataSeries.visible = true;
}
e.chart.render();
}
},
data: [
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 5 },
{ x: 20, y: 9},
{ x: 30, y: 17 },
{ x: 40, y: 32 },
{ x: 50, y: 22 },
{ x: 60, y: 14 },
{ x: 70, y: 25 },
{ x: 80, y: 18 },
{ x: 90, y: 20}
]
},
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 31 },
{ x: 20, y: 35},
{ x: 30, y: 30 },
{ x: 40, y: 35 },
{ x: 50, y: 35 },
{ x: 60, y: 38 },
{ x: 70, y: 38 },
{ x: 80, y: 34 },
{ x: 90, y: 44}
]
},
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 25 },
{ x: 20, y: 30},
{ x: 30, y: 20 },
{ x: 40, y: 45 },
{ x: 50, y: 30 },
{ x: 60, y: 10 },
{ x: 70, y: 15 },
{ x: 80, y: 18 },
{ x: 90, y: 20}
]
}
]
});
chart.render();
document.getElementById("showAllSeries").onclick = function(){
//Works for a single element using index:
chart.options.data[0].visible = !chart.options.data[0].visible;
//Doesn't work, need to modify
//chart.options.data.forEach(visible = !visible);
chart.render();
};
<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
<br/>
<div id="chartContainer" style="height: 300px; width: 100%;"></div>
<center><button id= "showAllSeries" style= "margin: 10px;">Show/Hide All series</button></center>
UP:
Found solution with for loop:
for (var i = 0; i < chart.options.data.length; i++) {
chart.options.data[i].visible = !chart.options.data[i].visible;
}
But still interesting how should it work with foreach

forEach is an Array method that you can use to execute a function on each element in an array. On the other hand for is a loop that is more flexible.
In your case, you can hide all dataSeries onclick of button either using for or forEach. Check the code below:
var chart = new CanvasJS.Chart("chartContainer", {
title:{
text: "Test Button to Hide All Series"
},
legend: {
cursor: "pointer",
itemclick: function (e) {
if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
e.dataSeries.visible = false;
} else {
e.dataSeries.visible = true;
}
e.chart.render();
}
},
data: [
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 5 },
{ x: 20, y: 9 },
{ x: 30, y: 17 },
{ x: 40, y: 32 },
{ x: 50, y: 22 },
{ x: 60, y: 14 },
{ x: 70, y: 25 },
{ x: 80, y: 18 },
{ x: 90, y: 20 }
]
},
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 31 },
{ x: 20, y: 35 },
{ x: 30, y: 30 },
{ x: 40, y: 35 },
{ x: 50, y: 35 },
{ x: 60, y: 38 },
{ x: 70, y: 38 },
{ x: 80, y: 34 },
{ x: 90, y: 44 }
]
},
{
showInLegend: true,
type: "line",
dataPoints: [
{ x: 10, y: 25 },
{ x: 20, y: 30 },
{ x: 30, y: 20 },
{ x: 40, y: 45 },
{ x: 50, y: 30 },
{ x: 60, y: 10 },
{ x: 70, y: 15 },
{ x: 80, y: 18 },
{ x: 90, y: 20 }
]
}
]
});
chart.render();
document.getElementById("showAllSeries").onclick = function(){
chart.options.data.forEach(function(dataSeries) {
if (typeof (dataSeries.visible) === "undefined" || dataSeries.visible) {
dataSeries.visible = false;
} else {
dataSeries.visible = true;
}
});
/*var dataSeries;
for(var i = 0; i < chart.data.length; i++){
dataSeries = chart.options.data[i];
if (typeof (dataSeries.visible) === "undefined" || dataSeries.visible) {
dataSeries.visible = false;
} else {
dataSeries.visible = true;
}
}*/
chart.render();
};

<center><button id= "showAllSeries" style= "margin: 10px;">Show/Hide All series</button></center>

Thanks to Vishwas for detailed answer. Generally - yes, both for & forEach are fine usable here. I will mark it as correct, but it helped me to get more concise solution using forEach that I expected:
document.getElementById(""showAllSeries"").onclick = function(){
chart.options.data.forEach(function(dataSeries) {
dataSeries.visible = !dataSeries.visible })
chart.render();
};
Will leave it here for a history also:

if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {

} else {
e.dataSeries.visible = true;
}
e.chart.render();

Draw grid lines using Canvas js logarithmic chart

i have created a chart using canvas js library
but i am having issue while displaying grid lines on the chart
<!DOCTYPE HTML>

this is how i wanted the grid to be
this is how it looks now
anyone know how to properly format the grid lines, i have alse added demo snipped of how my data will look like

Minor grids are not available as of now. However by adding stripLines you can achieve the same as shown below.
var chart = new CanvasJS.Chart("chartContainer", {
title: {
text: "Axis Y with interval 10"
},
axisY: {
logarithmic: true,
gridThickness: 0,
tickThickness: 0,
labelFormatter: function(e) {
return ""
},
minimum: 10,
maximum: 101,
},
data: [{
type: "line",
dataPoints: [
{ x: 100, y: 71 },
{ x: 200, y: 55},
{ x: 300, y: 50 },
{ x: 400, y: 65 },
{ x: 500, y: 95 },
{ x: 600, y: 68 },
{ x: 700, y: 28 },
{ x: 800, y: 34 },
{ x: 900, y: 14}
]
}]
});
chart.render();
addStripLines(chart);
function addStripLines(chart) {
var stripLines = [];
for (var i = chart.axisY[0].minimum; i < chart.axisY[0].maximum;
(i += 10)) {
chart.axisY[0].addTo("stripLines", {
value: i,
label: i,
labelPlacement: "outside",
labelBackgroundColor: "transparent",
labelFontColor: "black",
color: "black"
});
}

Canvas js Charts not responding correctly in Bootstrap 3 Layout

I am UI Developer and I am using Bootstrap 3 and Canvas Js Charts like pie chart,column chart.
I have decided to place two charts in each row for desktop.And It works properly. But when I resize the browser window It doesnot stack two charts in mobile device. Rather the Pie Chart gone away only second chart only visible. Why this happen.

Bootstrap provides grid-classes to maintain responsiveness design. To explicitly set width for tablet or mobile devices, you need to add grid-classes of tablet and mobile along with desktop class.
Refer to Bootstrap-Grid for more info. And here is a link to refer to examples of Bootstrap-Grid in multiple devices like desktop, tablet and mobile devices.
Here is the working code for your issue.

canviasjs is not showing chart multiple times

I am facing problem to show chart multiple times in a page. following is my code. my application is dynamic. but if the following can show the chart twice or more, my problem will be solved.

You only have to add them together and make sure that your first created canvas is emptied whenever the second is created:
This is the JS you need:
var chart = new CanvasJS.Chart("chartContainer", {
title: {
text: "Using all form of color inputs",
fontColor: "#6A5ACD"
},
axisY: {
interlacedColor: "rgb(255,250,250)",
gridColor: "#FFBFD5"
},
data: [{
type: "column",
color: "darkgreen",
dataPoints: [
{
x: 10,
y: 71
}, {
x: 20,
y: 55
}, {
x: 30,
y: 50
}, {
x: 40,
y: 65
}, {
x: 50,
y: 95
}, {
x: 60,
y: 68
}, {
x: 70,
y: 28
}, {
x: 80,
y: 34
}, {
x: 90,
y: 14
}
]
}]
});
chart.render();
chart = {}; // empty your first chart
var chart1 = new CanvasJS.Chart("chartContainer1", {
title: {
text: "Using all form of color inputs",
fontColor: "#6A5ACD"
},
axisY: {
interlacedColor: "rgb(255,250,250)",
gridColor: "#FFBFD5"
},
data: [{
type: "column",

dataPoints: [
{
x: 10,

Look at this JSFIDDLE

Thanks everyone. I have exact solution with Google Chart.
