populating x-axis(Category) Highcharts ajax - json

I need assistance on how to dynamically bind my x-axis. I have written a webservice, that will fetch the data from the stored procedure.
I am stuck on displaying just the first column from the SP as for the x-axis.
$.ajax({

url: "/path/path.asmx/xpath",
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function(data) {
alert("X_axis function is being hit")
// Parse JSON data:
var jsonCategories = eval('(' + data + ')');
alert(jsonCategories);
// Pass parsed data to the chart:
$('#Div3').xAxis[0].setCategories(jsonCategories);
}
})
// };
$('#Div3').highcharts({
chart: {
type: 'areaspline',
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 1, y2: 1 },
stops: [
[0, '#2a2a2b'],
[1, '#3e3e40']
]
}
},

Apex charts in Angular 9

I have some problem using apex charts in angular 9, essentially I'm able to see the chart (line chart) when I mock the data as in the first screenshot, but I can't get data from REST API, I mean the chart disappears.
mocked datas
This is the method containing the chart:
drawGraph(){
this.projectService.getLineChartData(this.getID()).then((data) =>{
for(let i = 0; i<data.resourceListSize; i++){
this.chartOptions = {
series: [
{
name: "data",
data: [28, 29, 33, 36, 32, 32, 33]
},
{
name: "Low - 2013",
data: [12, 11, 14, 18, 17, 13, 13]
}
],
chart: {
height: 350,
type: "line",
dropShadow: {
enabled: true,
color: "#000",
top: 18,
left: 7,
blur: 10,
opacity: 0.2
},
toolbar: {
show: false
}
},
colors: ["#77B6EA", "#545454"],
dataLabels: {
enabled: true
},
stroke: {
curve: "smooth"
},
title: {
text: "Average High & Low Temperature",
align: "left"
},
grid: {
borderColor: "#e7e7e7",
row: {
colors: ["#f3f3f3", "transparent"], // takes an array which will be repeated on columns
opacity: 0.5
}
},
markers: {
size: 1
},
xaxis: {
categories: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul"],
title: {
text: "Month"
}
},
yaxis: {
title: {
text: "Temperature"
},
min: 5,
max: 40
},
legend: {
position: "top",
horizontalAlign: "right",
floating: true,
offsetY: -25,
offsetX: -5
}
};
}
})
}
Any help would be appreciated! Thank you
Step 1,
set the configuration with out data like below(minimum configuration)
this.chartOptions = {
series: [],
chart: {
height: 350,
type: "line"
},
xaxis: {}
}
Step 2:
Data from api response and set to "chartoptions" variable,
this.chartOptions.series=[{
name: "data",
data: [28, 29, 33, 36, 32, 32, 33]
}, {
name: "Low - 2013",
data: [12, 11, 14, 18, 17, 13, 13]
}
];
this.chartOptions.xaxis=
{
categories: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul"]
}

How to update just data attribute under series in highcharts with json?

I am currently new on this and I am looking for the easiest way to load, from a json file, the data for different series, but keeping other attributes of each serie as they are in the javascript.
So as shown in the below code, there are two series "Carbon" and "Add". The JSON file will just have the data for both series:
[
{"data":[70]},
{"data":[-30]}
]
The script that I have is as the one below:
$(function () {
$(document).ready(function(){
$.getJSON('carbonData.json', function(data) {
var carbon = new Highcharts.chart({
chart: {
renderTo: 'Carbon',
marginLeft:-30,
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false,
type: 'bar'
},
credits: {
enabled: false
},
title: {
text: ''
},
xAxis: {
labels:{enabled:false},
lineWidth: 0,
minorTickLength: 0,
tickLength: 0,
gridLineWidth: 0,
minorGridLineWidth: 0,
categories: ['']
},
yAxis: {
labels:{
enabled: false,
},
plotLines: [{
value: -30,
label: {
text: 'Target<br/>30 kg/t',
style:{fontSize: "10px"},
rotation:0,
align: 'center',
x: 0,
y:25
}
},{
value: 70,
label: {
text: 'Target<br/>70 kg/t',
style:{fontSize: "10px"},
rotation:0,
align: 'center',
x: 0,
y:25
}
}],
gridLineWidth: 0,
minorGridLineWidth: 0,
min: -45,
max:75,
title: {
text: ''
}
},
colors:['#4572A7','#AA4643'],
legend: {
enabled: false,
},
tooltip: {
enabled:false,
},
plotOptions: {
series: {
stacking: 'normal',
}
},
series: [{
name: 'Carbon',
data: [70],
dataLabels: {
enabled:true,
x: 16,
format: '{series.name}<br/>{point.y} kg/t',
style: {
align: 'center',
fontSize: "10px",
fontWeight:'normal',
textOutline: false,
fontFamily: 'sans-serif',
'text-anchor': 'middle'
}
}
}, {
name: 'Add',
data: [-30],
dataLabels: {
enabled:true,
x:13,
formatter: function() {
return this.series.name+'<br/>'+Math.abs(this.y)+' kg/t';
},
style: {
color: 'white',
align: 'center',
fontSize: "10px",
fontWeight:'normal',
textOutline: false,
fontFamily: 'sans-serif',
'text-anchor': 'middle'
}
}
}]
});
});
});
});
So I am looking to map the information of the JSON file to each of the series correspondingly.
Thanks.
Use setData method:
var data = [{
"data": [70]
},
{
"data": [-30]
}
]
var chart = Highcharts.chart('container', {
series: [{
color: 'red',
data: []
}, {
color: 'blue',
data: []
}]
});
document.getElementById("data").addEventListener('click', function() {
data.forEach(function(el, i) {
chart.series[i].setData(el.data);
});
});

Stacked bar chart from JSON file - seems to be ignoring a value

Pretty new to this stuff, so any help is greatly appreciated. To start off with, here is my JSON file's contents:
[
{
"drg": "NONSPECIFIC CEREBROVASCULAR DISORDERS W MCC",
"approved": 124,
"denied": 38
},
{
"drg": "SEIZURES WO MCC",
"approved": 138,
"denied": 26
},
{
"drg": "CHRONIC OBSTRUCTIVE PULMONARY DISEASE W CC",
"approved": 352,
"denied": 61
},

"denied": 29
},
{
"drg": "POISONING TOXIC EFFECTS OF DRUGS WO MCC",
"approved": 144,
"denied": 24
}
]
My stacked bar chart, which worked fine with a CSV file, keeps ignoring the "denied" value. I suspect the issue has something to do with my formatting of the "processed_json.push()" portion of my code. It renders the approved value stacked on top of itself. Here is the script file:
<script>
$(document).ready(function() {
var processed_json = new Array();
$.getJSON('/dashboard-test-data/denied-percentage-2015-chart.json', function(data) {
for (i = 0; i < data.length; i++) {
processed_json.push([data[i].drg, data[i].approved, data[i].denied]);
}

Here is what the end product should produce (screen grab from my csv version):
Correct
And here is what I'm getting from the JSON file: incorrect
Any assistance or guidance is greatly appreciated. Thanks.
Have a look at highchart's stacked bar chart example. For each series, data contains the array of values for that series.
series: [{
name: 'John',
data: [5, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
In your case, instead of creating the processed_json array of objects, you should create separate arrays containing each series' values.
Change the loop this way:
var xAxis = []
, approvedCount = []
, deniedCount = []
for (i = 0; i < data.length; i++) {
xAxis.push(data[i].drg);
approvedCount.push(data[i].approved);
deniedCount.push(data[i].denied);
Then adapt the chart's instantiation accordingly:
// (...)
xAxis: {
categories: xAxis
},
// (...)
series: [{
name: 'approved',
color: '#55B4E4',
data: approvedCount,
}, {
name: 'denied',
color: '#005079',
data: deniedCount,
}],
// (...)

Highchart speedometer take input from csv

I am trying to read the data from csv and display it as a input to Speedometer but I am unable to get the chart. Please tell me where i am going wrong.

}, {

}]
},
series: []
};
$.get('data.csv', function(data) {
var series = {
data: [],
name: 'Speed',
tooltip: {

}
};
series.data.push(parseFloat(data));
options.series.push(series);
alert("data "+options.series);
var chart = new Highcharts.Chart(options);
});
});
and the csv file is simple
data.csv has only one value 30.
or incase it is
t1,30
t2,40
t3,60
how do i display 3 corresponding speedometers with respective speed.
Your help is greatly appreciated.
Thanks in advance.
In your case data your data (from ajax) is a single string, but you need to split elements and then choose which should be parsed to integer (parseFloat).
