i am trying to get a plot (vizType: info/dual_line) that initially stops at a given Date (zoom should still work). Available data provides much more data points but the first view should be from 'Today' to '7 Days ago'.
This is my very first question here...please excuse if there is anything important missing.
Feed:
new FeedItem({
uid: "categoryAxis",
type: "Dimension",
values: ["CreationTimestamp"]
})
Dataset:
dimensions: [
name: CreationTimestamp,
value: "{CreationTimestamp}",
dataType: "date"
]
Properties:
plotArea: {
window: {
end: {
categoryAxis: {
CreationTimestamp: new Date(1673442669000)
}
}
}
}
Data:
[
{
CreationTimestamp: date-object,
A: 12,
B: ...,
...
},
...
]
I also tried to use the millis of the Date instead of the date-object in data and vizProperties. it produces the same result.
The Visualization looks correct in both cases (Date-Object and Millis) but the plot end does never match the one from properties.
I implemented it that way that the value for plotArea.window.end.categoryAxis.CreationTimestamp matches exactly one of the values in data (same result as before - the plot is drawn till the last data point).
Is there any obvious problem with my implementation or am i expecting the wrong result?
After debugging sap-viz-info-charts.js i found out that i simply have to set the date.getTime() value to plotArea.window.end.categoryAxis. basically like so:
plotArea: {
window: {
end: {
categoryAxis: {
CreationTimestamp: 1673442669000
}
}
}
}
after this change i still can zoom in and out and the vizFrame plot initially ends at the correct timestamp.

I want to make a 3d array that will represent years, months and days:
[years[months[days]]]
And so I made a simple function that does this perfectly, for each day I am populating a default object:
function generateEmpty3dArray() {
// i did that on purpuse with [[]], im doing it just for 1 year atm,
// thats why i am using index 0
const array = [[]];
const months = 12;
for(let month = 0; month < months; month++) {
const monthDays = new Date(2021, month + 1, 0).getDate();
array[0].push([]);
for(let day = 0; day < monthDays; day++) {
array[0][month].push({shift: "X"})
}
}
console.log(array)
}
The array that is generated is exactly what I want, my issue is in defining the Person schema:
const personSchema = new mongoose.Schema({
schedule: {
type: Array,
default: generateEmpty3dArray() //????
}
})
I dont know how to populate the default field, what I want to happen is, whenever a new Person is created into the database, I want him to receive that empty 3d array, so that I can then work with it and set different shifts.
The problem is that, I have no idea how to both specify what the specific value of each day should look like [[[{shift: {type: String, enum: shifts}}]]] and at the same time, create the default array for the whole thing.
This is what worked:
schedule: {
type: [
[
[
{
shift: { type: String, required: true, enum: shifts },
},
],
],
],
default: generateEmpty3dArray(),
},
I'm using DataTables jQuery plugin in Aurelia component. using column ordering and it works well excluding columns with dates.
Inside this columns I'm using value-convertet to convert isoString value to DD.MM.YYYY date format. Value covreters usage leads to wrong date column ordering, but if I'm not using value-converter everything works well. Unfortunately I didn't find any reason why it doesn't work correctly.
Wrong filtering example: I see rows with date value like 27.05.2010 before 18.05.2017
DataTables init:
$('#searchResultsTable').dataTable({
destroy: true,
searching: false,
paging: false,
orderMulti: false,
order: [[ 2, "desc" ]],
dateFormat: 'DD.MM.YYYY'
});
Date value converter (using moment library):
import * as moment from 'moment';
export class DateFormatValueConverter {
toView(value: Date, format: string): string {
if (value) {
return moment(value).format(format);
}
return null;
}
fromView(value: string, format: string): Date {
var isValid = moment(value, format, true).isValid();
if (value && isValid) {
return moment(value, format).toDate();
}
return null;
}
}
UPDATE:
Ordered with value converter
Orderd without ValueConverter(ordered like it should 2017 year value on the top)
The ordering mechanism of the data table is working correctly - it's your understanding that's off I'm afraid.
When ordering in descending order, any that start with 27. will be at the top, as they're the "biggest". Within all the dates that start with 27, it'll order on the month, biggest first, and then the year.
The order mechanism doesn't realise you're ordering a date so we need to look at the Custom Sorting Plugins;
https://www.datatables.net/plug-ins/sorting/
And specifically the Date-De plugin - as that matches your date format;
https://www.datatables.net/plug-ins/sorting/date-de
An example taken from the above page;
$('#example').dataTable( {
columnDefs: [
{ type: 'de_datetime', targets: 0 },
{ type: 'de_date', targets: 1 }
]
});
I get array of date from json as 1420185600000,1420531200000,1420617600000,1420704000000,1420790400000,1420876800000. How do I format it to show the correct date in the XAxis labels of the highcharts?
You need to tell highcharts that the xAxis is a date type.
xAxis: {
type: 'datetime'
},
You may need extra formatting if you want the date displayed in some form other than the default. That can be done via the labels.formatter.
Sample code that lets you do what you want (minus what formatting you want your date in):
xAxis: {
categories: [1420185600000,1420531200000,1420617600000,1420704000000,1420790400000,1420876800000],
labels: {
formatter: function () {
return new Date(this.value);
}
}
},
You would then need to determine what parts of your new date string you actually want to show. The sample above doing return Date(this.value) is the kitchen sink approach.
UPDATE: If you want the strings formatted, Highcharts gives you functions to set up the date string. See this fiddle (same as fiddle linked in the comments below with formatter using highcharts): http://jsfiddle.net/CaptainBli/psd3ngsh/13/
xAxis: {
type: "datetime",
categories: xArray,
labels: {
formatter: function () {
return Highcharts.time.dateFormat('%Y-%m-%d %H:%M:%S.%L', new Date(this.value));
}
}
},
arrayOfDatesFromJson = arrayOfDatesFromJson.map(function (element) {
return new Date(element);
});
Well there seems to be a multitude of similar questions, but none that I can find answering this specific question.. so here goes..
Have a working Kendo UI grid. My datasource is returning a timestamp - here's the JSON response coming back to the code:
You'll notice that the next line is also a date.. returned by MySQL as a standard DateTime format - which I would be happy to use directly. But I've converted the date to a timestamp which I thought would be more universal. (??)
Now I need to do two things - format the timestamp into a readable date and edit the date so it can be saved back to the datasource. But let's tackle formatting first.
My code to display the column currently looks like this:
{ title: "Trial<br>Date",
field: "customer_master_converted_to_customer_date",
format: "{0:d/M/yyyy}",
attributes: {
style: "text-align: center; font-size: 14px;"
},
filterable: true,
headerAttributes: {
style: "font-weight: bold; font-size: 14px;"
}
},
Although I've tried..
toString(customer_master_converted_to_customer_date, "MM/dd/yyyy")
.. and several variations of that - in terms of format string. And yes, I've tried entering:
type: "date",
No matter what I do, I only get the timestamp.
Anyone?
You need to convert the timestamp to a JavaScript date first. Here is a sample implementation:
$("#grid").kendoGrid({
dataSource: {
data: [
{ date: 1371848019 }
],
schema: {
model: {
fields: {
date: {
type: "date",
parse: function(value) {
return new Date(value * 1000);
}
}
}
}
}
}
});
Here is it live: http://jsbin.com/utonil/1/edit
I just had the same problem and i tried this and now works perfectly, good luck.
template :#= kendo.toString(new Date(parseInt(dateOfBirth)), 'yyyy-MM-dd')#"
whre dateOfBirth is the date to format, the result will be like this : 2015-09-11.
good luck.
Thank you #Atanas Korchev, that worked for me, here is what I ended up doing:
// in datasource
schema:{
model: {
fields: {
date: { type: "date",
parse: function(value) {
return new Date(value);
}
}, // … other fields
// in columns
columns: [
{
field: "date",
title: "Date",
type: "date",
format: "{0:dd MMM yyyy}"
},
// ... other columns
]
The easiest way to use the TimeStamp format data from your database for KendoGrid.
https://stackoverflow.com/a/67106362/5671943
<kendo-grid-column class="CreatedAt" field="CreatedAt" title="title"
[width]="120" [headerStyle]="{'background-color': '#36455a','color': '#fff'}"
[style]="{'background-color': '#36455a','color': '#fff'}">
<ng-template kendoGridCellTemplate let-dataItem>
{{dataItem.CreatedAt | date:"yyyy/MM/dd HH:mm:ss"}}
</ng-template>
</kendo-grid-column>
I've been trying to retrieve a date value and an integer value from the database, using the following code:
var l_alsChampsMois, l_stoDonneesMois;
try {
l_alsChampsMois = [
{name: "date_mois", type: "date", dateFormat: "Y-m-d"},
{name: "indice", type: "integer"}
];
l_stoDonneesMois = new Ext.data.JsonStore({
fields: l_alsChampsMois,
autoLoad: false,
proxy: {
type: "ajax",
url: "/commun/req_sql/req_ind_per_mois.php",
reader: {
type: "json",
root: "rows"
},
// some configs to use jsFiddle echo service (you will remove them)
actionMethods: {
read: "POST"
},
extraParams: {
key:"test"
}
},
listeners: {
load: function(objStore, alsLignes, blnOk, objOptions) {
window.alert("Mois fin : " + objStore.getAt(0).get("date_mois"));
}
}
});
l_stoDonneesMois.load({params: {
p_idsoc: l_strIdSociete,
p_mois: l_datDebut.getMonth() + 1,
// getMonth renvoie 0 pour janvier, etc.
p_annee: l_datDebut.getFullYear(),
p_debut: 1,
p_etape: 1
}
});
with l_strIdSociete and l_datDebut being variables previously assigned and /commun/req_sql/req_ind_per_mois.php the PHP page that retrieves the data and converts it to JSON.
It seems to work fine (indeed, Firebug tells me the load does retrieve a data structure with "date_mois" and "indice" containing the values I expect them to), only the window.alert returns undefined. If I replace "date_mois" with "indice", it returns the expected value for "indice".
I've tried to use objStore.getAt(0).getData()["date_mois"], to no avail.
My only clue about this is that "date_mois" in the data structure shown by Firebug is an Object, but even so it shouldn't be undefined, now should it? I looked up http://docs.sencha.com/ext-js/4-1/#!/api/Ext.data.Field-cfg-type that wasn't exactly forthcoming with straight answers.
So what did I do wrong there?
If you need current time you can use php time function(note: it returns seconds, JS uses milliseconds), in another case you need to convert by mktime function.
