I am trying to animate a plotly chart using the UpdateMenu's animate method.
I can't get it to animate back to the original trace.
In the example below, I can change the chart to trace 2. But it does not go back to trace 1.
Here is a code example of my problem
//myPlot = document.getElementById('chart')
var trace1 = {
x: [1],
y: [1],
type: 'scatter',
mode: 'markers',
name: 'Trace 1',
}
var trace2 = {
x: [.5],
y: [.5],
type: 'scatter',
mode: 'markers',
name: 'Trace 2',
}
var frames = [{
name: 'trace 1',
data: [trace1]
},
{
name: 'trace 2',
data: [trace2]
}
]
console.log(frames)
var layout = {
yaxis: {
range: [0, 2]
},
xaxis: {
range: [0, 2]
},
updatemenus: [{
buttons: [{
method: 'animate',
args: [
['trace 1']
],
label: 'One'
},
{
method: 'animate',
args: [
['trace 2']
],
label: 'Two'
}
]
}]
}
Plotly.newPlot("chart", [trace1], layout).then(function() {
Plotly.addFrames('chart', frames);
});

and a modified code example of their working sample.
In the working sample, you can change between the three traces using the drop down.
For some reason you can't put the trace in the list for data (inside the frames variable). You need to set the data x and y values manually.
//myPlot = document.getElementById('chart')
var trace1 = {
x: [1],
y: [1],
type: 'scatter',
mode: 'markers',
name: 'Trace 1',
}
var trace2 = {
x: [.5],
y: [.5],
type: 'scatter',
mode: 'markers',
name: 'Trace 2',
}
var frames = [{
name: 'trace 1',
data: [{
x: trace1.x,
y: trace1.y
}]
},
{
name: 'trace 2',
data: [{
x: trace2.x,
y: trace2.y
}]
}
]
//console.log(frames)
var layout = {
yaxis: {
range: [0, 2]
},
xaxis: {
range: [0, 2]
},
updatemenus: [{
buttons: [{
method: 'animate',
args: [
['trace 1']
],
label: 'One'
},
{
method: 'animate',
args: [
['trace 2']
],
label: 'Two'
}
]
}]
}
Plotly.newPlot("chart", [trace1], layout).then(function() {
Plotly.addFrames('chart', frames);
});

Hi,
this is my first post on stack so plz correct if wrong. I wish to know how do I access the properties of highstock chart in the above example. eg. if i want to set the 'selected' property of 'rangeselector' externally through code how to do it. Any help will be highly appreciated.
Thanks
You can:
Store a chart in a variable:
const chart = Highcharts.stockChart('container', {...});
chart.rangeSelector.buttons[0].element.dispatchEvent(new Event('click'));
Use load event:
Highcharts.stockChart('container', {
chart: {
events: {
load: function() {
this.rangeSelector.buttons[0].element.dispatchEvent(new Event('click'));
}
}
},
...
});
Use a callback function:
Highcharts.stockChart('container', {
...
}, function(chart) {
chart.rangeSelector.buttons[0].element.dispatchEvent(new Event('click'));

I am new to coding and am trying to make a barchart with eCharts. I have made a simple bar chart example but now I want to make a thick outline for the bars on the chart. This is my code.

How do I add a thick black outline on the bars?
You can use the option barBorderColor and barBorderWidth to set the color and width of the border respectively for each bar.
Below is an example based on your existing code.
var myChart = echarts.init(document.getElementById('main'));
// specify chart configuration item and data
var option = {
title: {
text: 'ECharts entry example'
},
tooltip: {},
legend: {
data: ['Sales']
},
xAxis: {
data: ["shirt", "cardign", "chiffon shirt", "pants", "heels", "socks"]
},
yAxis: {},
series: [{
name: 'Sales',
type: 'bar',
data: [5, 20, 36, 10, 10, 20],
//Added item style
itemStyle: {
normal: {
barBorderWidth: 5,
barBorderColor: "#000"
}
}
}]
};
// use configuration item and data specified to show chart
myChart.setOption(option);

I'm an beginner in js code and i want to use Highcharts to construct a treemap with color from a csv.
My csv looks like that :
Name,Value,colorValue
The first column is the name.
The second one is the percentage of activity.
The third one is a color attribute to say if the percentage (of the 2nd column) has been increase or decrease (Color red to green).
Do someone has an example ?
Because it doesn't work, nothing happen (no error too), i think it come from the csv load.
Here my actual code :

</html>
my Js :
Highcharts.chart('container', {
colorAxis: {
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[5]
},
series: [{
type: 'treemap',
layoutAlgorithm: 'squarified',
data: {
csv: document.getElementById('data').innerHTML,
seriesMapping: [{
colorValue: 2
}]
}
}],
title: {
text: 'Highcharts Treemap'
}
});
The CSV data properties should not be inside a series object but chart object, like that:
Highcharts.chart('container', {
colorAxis: {
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[5]
},
data: {
csv: document.getElementById('data').innerHTML,
seriesMapping: [{
colorValue: 2
}]
},
series: [{
type: 'treemap',
layoutAlgorithm: 'squarified',
keys: ['name', 'value', 'colorValue']
}],
title: {
text: 'Highcharts Treemap'
}
});

When I only have one chart, nothing's gone wrong, but when I try to add one more chart, my charts become so large and my page layout becomes so messy. Can you guys figure out what's wrong with my code? Thanks.
As per chartjs documentation:
Detecting when the canvas size changes can not be done directly from
the CANVAS element. Chart.js uses its parent container to update the
canvas render and display sizes. However, this method requires the
container to be relatively positioned and dedicated to the chart
canvas only. Responsiveness can then be achieved by setting relative
values for the container size
Source: https://www.chartjs.org/docs/latest/general/responsive.html
You should wrap your canvas into div and add width,height into it.
Here is the change I did
<div style="width:240px;height:240px">
<canvas id="layanan"></canvas>
</div>
<div style="width:240px;height:240px">
<canvas id="layanan_subbagian" ></canvas>
</div>
$(function () {
var ctx = document.getElementById("layanan").getContext('2d');
var data = {
datasets: [{
data: [10, 20, 30],
backgroundColor: [
'#3c8dbc',
'#f56954',
'#f39c12',
],
}],
labels: [
'Request',
'Layanan',
'Problem'
]
};
var myDoughnutChart = new Chart(ctx, {
type: 'doughnut',
data: data,
options: {
maintainAspectRatio: false,
legend: {
position: 'bottom',
labels: {
boxWidth: 12
}
}
}
});
var ctx_2 = document.getElementById("layanan_subbagian").getContext('2d');
var data_2 = {
datasets: [{
data: [10, 20, 30],
backgroundColor: [
'#3c8dbc',
'#f56954',
'#f39c12',
],
}],
labels: [
'Request',
'Layanan',
'Problem'
]
};
var myDoughnutChart_2 = new Chart(ctx_2, {
type: 'doughnut',
data: data_2,
options: {
maintainAspectRatio: false,
legend: {
position: 'bottom',
labels: {
boxWidth: 12
}
}
}
});

Try to add
options: {
responsive: false
}
I found two solutions:
You have to put the charts in a container such as a div. <canvas> is an element semantically dedicated for drawing graphics dynamically via scripting. <div> is a general-purpose container. The important point is: width and height properties are not the size in px but the ratio between them. <canvas id="layanan" width="240px" height="240px"></canvas> would result into a 1:1 ratio, but you need a parent container to work with. In the example below, I put a div around each canvas.
You can disable this feature by setting maintainAspectRatio to false. Removing the divs from my code and setting this into yours gives the same result :)
Cheers!

But when I type this : alert(data.datasets[0].data); I get nothing... basically I just want to express this 426777.148122 which is part of the data but I don't know how to do it, I thought to write this data.datasets[0].data but it does not work...
Any ideas ?
Thank you very much !
Try:
alert(JSON.stringify(config.data.datasets[0].data[0]));
You will need JSON.stringify because config.data.datasets[0].data is also an array of objects
or
alert(config.data.datasets[0].data[0].x);
To get the X value of the first entry of config.data.datasets[0].data
