How to configure ZingChart width and height? - javascript

I'm trying to use ZingChart. Trying to build gauge widget. Question is for those who worked with zingChart. How to configure width and height of space around chart. So here is what i'm saying about:
White container is a div with 100% width and height. All yellow space is plotarea of the zingChart, and in the center is gauge.
I want to cut all yellow space at the top and bottom around gauge. How to configure that?
Here is my chart config in react:
import React from 'react'
import './PlanGauge.sass'
import 'zingchart/es6'
import ZingChart from 'zingchart-react'
import WidgetTile from '../WidgetTile/WidgetTile'
function PlanGauge({ title }) {
const widgetConfig = {
minValue: 0,
maxValue: 150000,
currentValue: 100000,
}
const chartConfig = {
type: 'gauge',
'scale-r': {
aperture: 180,
values: `${widgetConfig.minValue}:${widgetConfig.maxValue}`,
ring: {
size: 12,
'background-color': '#F2F4F6',
tick: {
visible: false,
},
},
center: {
visible: false,
},
tick: {
visible: false,
},
item: {
//Scale Label Styling
visible: false,
},
},
plot: {
size: '100%',
},
series: [
{
values: [widgetConfig.currentValue],
'background-color': '#000',
'border-color': 'red',
indicator: [4, 4, 0, 0, 0.9],
},
],
plotarea: {
marginTop: 0,
marginBottom: 0,
backgroundColor: 'yellow',
},
}
return (
<WidgetTile title={title}>
<ZingChart data={chartConfig} />
</WidgetTile>
)
}
export default PlanGauge

Please set padding in the ZingChart configuration's plot object to control the area around it. The Plot object controllers the styling of the chart.

Set margin in the ZingChart configuration.
plotarea: {
margin: '0 0 0 0',
},
It works for me.

How to align a pie chart to the left in highcharts js?

I'm trying to pin a pie chart to the left.
A negative marginLeft and center: ['20%', '50%'] don't give me what i need
since when changing the screen width the position of the chart also changes.
I am using Vue 3 composition api
series: [{
center: ['20%', '90%'],
size: '150%',
innerSize: '65%',
data: [
{
name: 'Valid',
y: 10,
color: '#13CE66'
},
{
name: 'Failed Verification',
y: 5,
color: '#FF4949'
}
],
showInLegend: true
}]
It should be like this:
Use the chart.marginLeft property
Example config:
chart: {
type: 'pie',
width: 400,
height: 200,
marginLeft: -230
},

ChartJS: single bar of bar chart. I want a border around entire bar, including the max Y-value

I want to create a single bar using a bar chart. The setup is that the user can select different choices (representing the colors). In this example (codesandbox link below) I have a bar that has a max value of 90.000. The three chosen values are 20.000, 30.000 and 15.000, totaling 65.000.
Now, my goal is to have a border around this entire bar, not just the colors. In the image below this is represented with the red border. Currently I do this by putting a container element around my canvas element, but I would like to do this in the canvas itself, without using a container element. Someone has an idea on how to do this?
Codesandbox link
You need to define different dataset properties such as borderSkipped, borderRadius, borderWidth to achieve what you're looking for.
Don't know why but I also had to define the data of the dataset at the bottom as a floating bar in order to see the rounded border.
data: [[0, 20000]]
Please take a look at the runnable code below and see how it could work.
new Chart('chart', {
type: 'bar',
data: {
labels: [''],
datasets: [{
label: "currentAmount",
data: [[0, 20000]],
backgroundColor: "#bbb",
borderColor: "#f00",
borderWidth: 2,
borderSkipped: 'top',
borderRadius: 30,
barPercentage: 0.5
},
{
label: "amount 1",
data: [30000],
backgroundColor: "orange",
borderColor: "#f00",
borderWidth: { left: 2, right: 2 },
barPercentage: 0.5
},
{
label: "amount 2",
data: [15000],
backgroundColor: "green",
borderColor: "#f00",
borderWidth: { left: 2, right: 2 },
barPercentage: 0.5
},
{
label: "remaining",
data: [25000],
backgroundColor: "#fff",
borderColor: "#f00",
borderWidth: 2,
borderSkipped: 'bottom',
borderRadius: 30,

Apex Chart - How to target and style one specific grid line?

Does anyone has clue how to target specific grid line and style like in the example?
I know how to dash line with:
grid: {
strokeDashArray: 10,
},
But how can I target grid line according to the tick value?
Desired result
Only way you can do it is via css
.apexcharts-gridline:nth-child(2) {
stroke-dasharray: 10;
}
Or use annotations instead https://apexcharts.com/docs/annotations/
I have sorted it by using annotations property. Here is an example:
// Breakdown line
annotations: {
position: 'front',
yaxis: [
{
y: 3000,
strokeDashArray: 5,
label: {
position: 'left',
borderColor: 'transparent',
textAnchor: 'middle',
offsetY: -10,
offsetX: 50,
style: {
color: '#D0D4D9',
background: "transparent",
},
text: ''
}
}
]
}

Highcharts - Solid Gauge - Inconsistent Styling and Improper Values

I have a website which makes use of HighCharts Solid Gauge .
There are two rows of gauges.
The first row of gauges is built as follows.
var workgroups =['WG01','WG02','WG04',
'WG05','WG06','All'];
$(function ()
{
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: 'Gauge',
pane: {
// Positioning
center: ['50%', '60%'],
// img size
size: '100%',
// full circle/half circle
startAngle: -90,
endAngle: 90,
// gauge coloring
background: {
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || '#000',
// Inner semi circle sizing
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
// Set the limits for coloring
[0.1, '#55BF3B'], // green
[0.4, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
// Outside Line buffer
lineWidth: 0,
minorTickInterval: null,
tickPixelInterval: 400,
tickWidth: 0,
title: {
// Title Location
y: -30
},
labels: {
style:{
color: "#000000",
fontSize: "13px"
},
// Bottom Label Offset
y: 15,
distance: -10,
}
},
plotOptions: {
solidgauge: {
dataLabels: {
style:{
color: "000000",
fontSize: "15px"
},
borderWidth: 0,
useHTML: true
}
}
}
};
// The gauges
for( i in workgroups){
if(workgroups[i] == 'All'){
header = "All";
gaugeOptions.yAxis['stops'] = [[.5, '#000000']]
}else{
header = "WG" + workgroups[i].slice(-2);
}
$('#'+workgroups[i]).highcharts(Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: 100,
title: {
style:{
color: "#000000",
fontWeight: 'bold',
fontSize: '22px'
},
text: header
}
},
credits: {
enabled: false
},
series: [{
name: workgroups[i],
data: [0],
dataLabels: {
y: 40,
format: '<div style="text-align:center"><span style="font-size:25px;color:' +
((Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black') + '">{y}</span><br/>' +
'<span style="font-size:12px;color:silver">clients</span></div>'
},
}]
}));
}
}
);
and results in the following image.
This is fine, proper values, all styles fit where they are supposed to.
After doing these gauges, we then do a second row of gauges.
The (Current) Configuration for these gauges are:
var application_array = new Array(3);
application_array['Sapphire'] = 50;
application_array['Magic Bullet'] = 35;
application_array['Boris'] = 30;
$(function ()
{
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: 'Gauge',
pane: {
// Positioning
center: ['50%', '85%'],
// img size
size: '150%',
// full circle/half circle
startAngle: -90,
endAngle: 90,
// gauge coloring
background: {
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || '#000',
// Inner semi circle sizing
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
// Set the limits for coloring
[0.1, '#55BF3B'], // green
[0.4, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
// Outside Line buffer
lineWidth: 0,
minorTickInterval: null,
tickPixelInterval: 400,
tickWidth: 0,
title: {
// Title Location
y: -30
},
labels:{
y:13
}
},
};
// Build the gauges here
var license_gauges = document.getElementsByClassName('gaugeCell2');
var myLength = license_gauges.length;
for (i=0; i <myLength; i++){
var header = license_gauges[i].id;
var selector = "[id='"+header+"']";
if (header == 'Boris'){
var max_value = 30;
}else if (header == 'Magic Bullet'){
var max_value = 35;
}else if (header == 'Sapphire'){
var max_value = 50;
}
console.log(header)
$(selector).highcharts(Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: max_value,
title: {
style:{
color: "#000000",
fontWeight: 'bold',
fontSize: '22px'
},
text: header
}
},
credits: {
enabled: false
},
series: [{
name: header,
data: [0],
}]
}));
}
});
Which Produces the following BAD Gauges
My Question
1) In the second row of gauges, Why is it printing 25 as max for the 2nd and 3rd gauge?
- I have tried an associate array to hold the proper value, same issue occurs
I have tried a function which returns a static value, same issue occurs
I have tried logic in the gauge creation itself, same issue occurs
I have tried writing a static value as max, and all gauges get the proper value
2) In the second row of gauges, why is it that the max Value, for the second and third gauges is inconsistently formatted with the first gauge?
I have tried virtually every layout configuration I can think of, but yet it stays the same issue.
When Using a static max value, this issue does not occur.
Do I need to make an individual gaugeoption for each gauge since they have different max values? I would like to use 1 gauge style for the top row and 1 gauge style for the bottom row (fatter).
A JSFiddle has been created here. There is most likely extraneous code (especially css), as I wanted to get it up and running quickly.

Thanks for reading
Why is it printing 25 as max for the 2nd and 3rd gauge?
It isn't. That is, the max isn't 25, but the drawn axis label shows the value 25, as there is an axis tick at this value. The max value is not showing with a label.
why is it that the max Value, for the second and third gauges is inconsistently formatted with the first gauge?
The position is inconsistent because the 25 label is in varying positions depending on what the max value is. In your case it is 35 and 30 for the last two gauges.
Do I need to make an individual gaugeoption for each gauge since they have different max values?
No. From my understanding you want a label at the start (0) and end (max_value). To get this you need to ensure that the axis ticks (which have associated labels) are at these positions, and only these.
A simple way is this (JSFiddle):
yAxis: {
min: 0,
max: max_value,
tickPositions: [0, max_value], // Ensure position of ticks, which have labels
// ...
}
I was having the same issue, but following what Halvor Strang said solved my problem like so
displayOptions.yAxis.min = widget.display.minimum;
displayOptions.yAxis.max = widget.display.maximum;
displayOptions.yAxis.tickPositions = [widget.display.minimum, widget.display.maximum];
distorted labels
- Minimum and maximum out of place

Knockout-kendo radial gauge not drawing correctly when initialized using data-bind

Having issues with the Knockout-Kendo radial gauge in my application.
I'm trying to initialize it via the data-bind property, but it does not appear to be resizing itself correctly.
<div id="speedGauge" data-bind="kendoRadialGauge: $parent.speedGaugeOptions"></div>
...
self.speedGaugeOptions = {
renderAs: 'svg',
value: 0,
gaugeArea: {
background: 'transparent'
},
pointer: {
color: 'lightgray',
animation: {
speed: 100
}
},
scale: {
minorUnit: 75,
majorUnit: 150,
startAngle: -40,
endAngle: 220,
max: 300,
min: -300,
labels: {
position: 'inside',
font: '10px Arial,Helvetica,sans-serif'
},
ranges: [
{
from: -300,
to: -200,
color: "darkgray"
},
{
from: 300,
to: 200,
color: "darkgray"
}
],
rangeSize: 5,
rangeDistance: -5,
rangePlaceholderColor: '#f2f2f2'
}
Here comes the fun part;
When the page has activated (using durandal), the gauges are drawn like this:
In order for the gauge to scale correctly and fit inside the gray circle, I have to redraw it like this (either from the browser console, or in the .js file):
$("#speedGauge").data("kendoRadialGauge").redraw()
When doing so, my gauge looks the way it's suppose to;
Now, I've tried creating it using the regular Kendo implementation - and that works just fine resulting in the gauge to be drawn correctly like in the image above;
<div id="speedGauge"></div>
...
self.activate = function () {
createGauge();
}
...
function createGauge() {
$("#speedGauge").kendoRadialGauge({
renderAs: 'svg',
value: 0,
gaugeArea: {
background: 'transparent'
},
pointer: {
color: 'lightgray',
animation: {
speed: 100
}
},
scale: {
minorUnit: 75,
majorUnit: 150,
startAngle: -40,
endAngle: 220,
max: 300,
min: -300,
labels: {
position: 'inside',
font: '10px Arial,Helvetica,sans-serif'
},
ranges: [
{
from: -300,
to: -200,
color: "darkgray"
},
{
from: 300,
to: 200,
color: "darkgray"
}
],
rangeSize: 5,
rangeDistance: -5,
rangePlaceholderColor: '#f2f2f2'
}
});
}
Does anyone have an idea of what might be wrong here?
A colleague suggested to do a forced redraw of the gauges on durandals attached event, which solved the problem for now. The actual resizing of the gauge is not visible with this solution.
self.attached = function(element) {
$(element).find("[data-role='radialgauge']").each(function () { $(this).data("kendoRadialGauge").redraw(); });
};
I've reported the issue here.
