HighCharts : Xaxis lables misplaced - json

I want to label xaxis with values from JSON data that is happening but it is printing it at wrong place as shown in screenshot :
Here only seven values are present its labeled in that manner but actual data is plotted by leaving a gap of one. For example at 11th there is value and then again at 13t so total seven values but taking 14 places and label properly taking there first seven places how to match labels and bar graph
Following is my code snippet :
var obj = data[$("#host").val()].stats_vol.result.sectoutput;
var my_data_list = [];
var my_data_list1 = [];
var my_data_list2 = [];
var volumes = [];
for(var key in obj) {
var avg_latency = parseInt(obj[key].avg_latency);
var read_latency = parseInt(obj[key].read_latency);
var write_latency = parseInt(obj[key].write_latency);
console.log(key);
volumes.push(key);
my_data_list.push('Average Latency', parseInt(avg_latency));
my_data_list1.push('Read Latency', parseInt(read_latency));
my_data_list2.push('Write Latency', parseInt(write_latency));
}
$('#graphcontainer3').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Volume Level Latency'
},
yAxis: {
tickInterval: 100,
title: {
text: 'Latency(ms)'
}
},
xAxis: {
categories: volumes,
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} ms</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 2
}
},
series: [{
name: 'Average latency',
data: my_data_list,
}, {
name: 'Read Latency',
data: my_data_list1,
}, {
name: 'Write Latency ',
data: my_data_list2,
}]
});
Can anyone help me in this code to make this work fine???

I rectified the problem by myself :) It just I was giving labels two times
var obj = data[$("#host").val()].stats_vol.result.sectoutput;
var my_data_list3 = [];
var my_data_list1 = [];
var my_data_list2 = [];
var volumes = [];
for(var key in obj) {
var avg_latency = parseInt(obj[key].avg_latency);
var read_latency = parseInt(obj[key].read_latency);
var write_latency = parseInt(obj[key].write_latency);
console.log(avg_latency);
volumes.push(key);
my_data_list3.push(parseInt(avg_latency)); //here no need to give label again as it is done my volume(key)
my_data_list1.push( parseInt(read_latency));
my_data_list2.push(parseInt(write_latency));
}
This is what I was expecting as output .Hope it might be helpful for someone else hence answered.

Is it possible that we can add dynamic borders to X axis labels and sub labels in chart.js?

I need to create dynamic borders to labels and sub labels of chart.js graph. Is there any way of achieving this scenario?.
Below is the output I am expecting.
Labels and sub labels are having borders
Has anyone been able to achieve this with the library?
Thanks in advance.
I have tried this code but unable to get borders to labels.

Razor chart.js labels/data not in sync

I have a Razor application that generates three columns of data to use in a chart graph. The page and javascript to do that looks like this:
<div><canvas id="myChart"></canvas></div>
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
<script>
var Maanden = [];
var Totalen = [];
#foreach (var m in Model.Grafieks)
{
#:Maanden.push("#m.maand" + "-" + "#m.jaar");
#:Totalen.push(#m.Total);
}
const ctx = document.getElementById('myChart').getContext('2d');
const myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: Maanden,
datasets: [
{ label: 'Facturen €',
data: Totalen,
backgroundColor: 'rgb(255, 255, 132)',
borderColor: 'rgb(255, 99, 132)',
borderWidth: 1,
}
]
},
});
</script>
Problem is that the labels are displayed OK but the data is off. Every second column is empty and its data pushed to the next column:
Chrome says:
Is there something wrong pushing the data into the arrays?
I had to convert the comma in decimal Totalen to a period!
#foreach (var m in Model.Grafieks)
{
#:Maanden.push("#m.maand" + "-" + "#m.jaar");
<text>bedrag = parsePotentiallyGroupedFloat("#m.Total");</text>
#:Totalen.push(bedrag);
}
function parsePotentiallyGroupedFloat(stringValue) {
stringValue = stringValue.trim();
var result = stringValue.replace(/[^0-9]/g, '');
if (/[,\.]\d{2}$/.test(stringValue)) {
result = result.replace(/(\d{2})$/, '.$1');
}
return parseFloat(result);
}
The function "parsePotentiallyGroupedFloat" is from here: Convert String with Dot or Comma as decimal separator to number in JavaScript

Google Visualization Column Chart set a data column from query as role: "Style"

I have a Google Visualization Column Chart from a query that works fine. I can set the a columns with a style role after the query by using the code snippet below. It adds a new column to the query data and sets the role as "Style". This colors each of the column chart bars accordingly. But I want to be able to use one of my query columns "C" for example as the color code and not have to add it afterward. I can't seem to get this to work. Any ideas? I posted more of my code below the snippet so you can see where I'm coming from. Thanks so much guys for any help you can give. Brandon
var data = response.getDataTable();
data.addColumn({type: "string", role: "style" });
data.setCell(0,2,'red');
data.setCell(1,2,'orange');
data.setCell(2,2,'green');
data.setCell(3,2,'yellow');
// More code above this, but I ommited it.
function drawDashboard() {
var query = new google.visualization.Query(
'URL');
query.setQuery('SELECT A, B, C');
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
data.addColumn({type: "string", role: "style" });
data.setCell(0,2,'red');
data.setCell(1,2,'orange');
data.setCell(2,2,'green');
data.setCell(3,2,'yellow');

dashboard.bind([scoreSlider], [table, columnChart]);
dashboard.bind([ClassFilter], [table, columnChart]);
// Draw the dashboard.
dashboard.draw(data);
}// More code below this, but I ommited it.
I'm not sure how you would add this to a column in the query but...
using a DataView with a calculated column should work...
Assumes the value you want to test is in the second column -- index 1
var data = response.getDataTable();
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
type: "string",
role: "style",
calc: function (dataTable, rowIndex) {
if (dataTable.getValue(rowIndex, 1) < 0.69) {
return 'color: red;';
} else if ((dataTable.getValue(rowIndex, 1) >= 0.69) && (dataTable.getValue(rowIndex, 1) <= 0.79)) {
return 'color: yellow;';
} else {
return 'color: green;';
}
}
}]);

KendoGrid refresh

I'm using KendoGrid to display some data fetched from my service.
The user selects some parameters (company and date) and cliks on a load button.
The user selects a month on a datePicker and the server will return data from that date plus 11 months.
I only display the grid after the user click on the load button.
Load function:
function loadGrid(e) {
var companyIds = [1, 3, 7]; // user select it
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var rowHeaders = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K"];
var _dataSource = function () {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: URL,
dataType: "json",
data: {
companyIds: companyIds,
date: kendo.toString(picker.value(), "yyyy-MM-dd") // user select it
}
}
},
schema: {
data: function (data) {
// function to handle data returned from server
var dataArray = [];
var index = 0;
for (var key in data[0]) {
if (Object.prototype.hasOwnProperty.call(data[0], key)) {
var property = key;
if (property == "date") {
continue;
}
key = {};
key["X"] = rowHeaders[index];
index++;
for (var i = 0; i < data.length; i++) {
var date = data[i].date;
var dateSplit = date.split("-");
var year = dateSplit[0];
var month = months[dateSplit[1] - 1];
var header = month + "_" + year;
key[header] = data[i][property];
}
dataArray.push(key);
}
}
return dataArray;
}
}
});
return dataSource;
};
$("#grid").kendoGrid({
scrollable: false,
editable: false,
dataSource: _dataSource()
});
}
When I click on the load button for the first time, the datasource is loaded and the grid is displayed correctly.
But, for instance, if I change the date on the datePicker and click on the load button again, the datasource is loaded with the correct data (new records for other months), but the grid is not refreshed.
If the first time I select the month Jan/2015, it loads and displays from Jan/2015 until Dec/2015, which is correct.
But if than I select the month Feb/2015, the datasource loads from Feb/2015 until Jan/2016 (correct), but the grid display the columns from Jan/2015 until Dec/2015, which is wrong. In this case, the column Jan/2015 is shown empty and the column Jan/2016 is not displayed.
Can someone point me to the right direction?
Thanks!
You should use a function for your dataSource -> transport -> read -> data:
data: function() {
return {
companyIds: companyIds,
date: kendo.toString(picker.value(), "yyyy-MM-dd") // user select it
};
}
UPDATE:
Here is how I would do it:
function loadGrid(e) {
$("#grid").data("kendoGrid").dataSource.fetch();
}
function getData() {
var companyIds = ...
var picker = ...
return {
companyIds: companyIds,
date: kendo.toString(picker.value(), "yyyy-MM-dd") // user select it
};
}
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: URL,
dataType: "json",
data: getData
}
},
schema: {
data: function (data) {
// function to handle data returned from server
var dataArray = [];
var index = 0;
for (var key in data[0]) {
if (Object.prototype.hasOwnProperty.call(data[0], key)) {
var property = key;
if (property == "date") {
continue;
}
key = {};
key["X"] = rowHeaders[index];
index++;
for (var i = 0; i < data.length; i++) {
var date = data[i].date;
var dateSplit = date.split("-");
var year = dateSplit[0];
var month = months[dateSplit[1] - 1];
var header = month + "_" + year;
key[header] = data[i][property];
}
dataArray.push(key);
}
}
return dataArray;
}
}
});
$("#grid").kendoGrid({
scrollable: false,
editable: false,
dataSource: dataSource
});
I ended up destroying and recreating the grid when the user clicks on load button.
$("#loadButton").kendoButton({
click: loadGrid
});
var loaded = false;
function loadGrid(e) {
if (value) {
if (loaded) {
var grid = $("#grid").data("kendoGrid");
grid.wrapper.empty();
grid.destroy();
}
$("#grid").kendoGrid({
scrollable: false,
editable: false,
autoBind: false,
dataSource: _dataSource()
});
$("#grid").data("kendoGrid").dataSource.read();
loaded = true;
} else {
e.preventDefault();
alert("aaaa");
}
}

Unable to format JSON from WCF for HighCharts?

My WCF returns this JSON and i want to bind to HighCharts Pie
Original from WCF -[{"AllRecordsUrl":"http:\/\/EMS\/sites\/IST\/report.aspx","EMSCenterName":"IST","EMSCenterUrl":"http:\/\/EMS\/sites\/IST","Count":2},{"AllRecordsUrl":"http:\/\/EMS\/sites\/LSS\/report.aspx","EMSCenterName":"LSS","EMSCenterUrl":"http:\/\/EMS\/sites\/LSS","Count":17}]
If i hardCode it in cart series as data: [....] it works but the dynamic proccesed data does not..
After processing - [{name: 'IST' , url: 'http://EMS/sites/IST/report.aspx' , y: 2 },{name: 'LSS' , url: 'http://EMS/sites/LSS/report.aspx' , y: 16 }]
Even after processing it to what i showed above highcharts Pie won't work with my data..
I am not sure what is wrong here, would appreciate some guidance
Here's what is done so far ...
function getDataForHub(json) {
var realArray = $.makeArray(json);
//debugger;
//console.log(JSON.stringify(realArray));
var obj = $.parseJSON(JSON.stringify(realArray));
var chartData = [];
$.each(realArray, function (index, item) {
var final;
var element;
var sB = '';
var name = '';
var url = '';
var y = '';
var color = '';
for (element in item) {
if (element == 'EMSCenterName') {
name = 'name' + ": " + "'" + item[element] + "'";
}
if (element == 'AllRecordsUrl') {
url = 'url' + ": " + "'" + item[element] + "'";
}
if (element == 'Count') {
y = 'y' + ": " + item[element];
}
}
sB = name + ' , ' + url + ' , ' + y ;
//console.log(sB);
var elements = [];
//adding each to an array before being pushed to th final array,
elements.push(sB);
chartData.push(elements);
});
return chartData;
