Imagine a simple line graph plotting a person count (y-axis) against a custom time value (x-axis), as such:
Suppose you have another dimension, say specific groupings of people, how do you draw a separate line on this graph for each group?
You have to use the PivotConfig here an example I used in Angular
(EDIT) Here is the Query
Query = {
measures: ['Admissions.count'],
timeDimensions: [
{
dimension: 'Admissions.createdDate',
granularity: 'week',
dateRange: 'This quarter',
},
],
dimensions: ['Admissions.status'],
order: {
'Admissions.createdDate': 'asc',
},
}
(END EDIT)
PivotConfig = {
x: ['Admissions.createdDate.day'],
y: ['Admissions.status', 'measures'],
fillMissingDates: true,
joinDateRange: false,
}
Code to extract data from resultset :
let chartData = resultSet.series(this.PivotConfig).map(item => {
return {
label: item.title.split(',')[0], //title contains "ADMIS, COUNT"
data: item.series.map(({ value }) => value),
}
})
Result Object (not the one in the chart):
[{
"label": "ADMIS",
"data": [2,1,0,0,0,0,0]
},{
"label": "SORTIE",
"data": [2,1,0,0,0,0,0]
}]
Here is what the output looks like!
The chart renderer in the Developer Playground is meant to be quite simplistic; I'd recommend creating a dashboard app or using one of our frontend integrations in an existing project to gain complete control over chart rendering.

I would like to write a test in Postman that validates there are no duplicate values in the array of objects. Here is an example response:
This is my json response :
{
"content": [
{
"id": "88848990-c4c8-4e7d-b708-3e69e684085b",
"name": "UPDATED",
},
{
"id": "42c37e1d-eed3-4f5c-b76a-7b915c05b0bf",
"name": "Swoop ",
},
{
"id": "88848990-c4c8-4e7d-b708-3e69e684085b",
"name": "United Test Airlines",
},
I can see 2 ids that are the same I want to write a test in postman to identify any duplicates in my results. If the test picks up duplicates then it must fail, if it does not pick up any duplicates it should pass. Note I am new to postman api testing.
The short and esay solution might be:
Save all id in an array
Create a set from this array
Compare size of the array and the set. If it equals, then no duplication. If not, there is a duplication.
const res = pm.response.json();
const ids = _.map(res.content, "id");
pm.test("check duplicate id", () => {
const setIds = new Set(ids);
pm.expect(ids.length).eql(setIds.size);
})
In moodle (4.0) I have the need to call
$this->output->render_from_template('core_courseformat/local/content/section/cmlist', $sectionData);
From within a renderer. The goal is to render the normal, native, cmlist component in a particular place on the page. But the way that I am currently getting the value of $section does not seem to work. My template renders nothing. I can see from the github source that this template expects data in this format:
Example context (json):
{
"cms": [
{
"cmitem": {
"cmformat": {
"cmname": "<a class=\"aalink\" href=\"#\"><span class=\"instancename\">Forum example</span></a>",
"hasname": "true"
},
"id": 3,
"module": "forum",
"extraclasses": "newmessages"
}
},
{
"cmitem": {
"cmformat": {
"cmname": "<a class=\"aalink\" href=\"#\"><span class=\"instancename\">Assign example</span></a>",
"hasname": "true"
},
"id": 4,
"module": "assign",
"extraclasses": ""
}
}
],
"hascms": true,
"showmovehere": true,
"movingstr": "Moving this activity: folder example",
"cancelcopyurl": "#",
"movetosectionurl": "#",
"strmovefull": "Move 'folder example' to this location"
}
}}
https://github.com/moodle/moodle/blob/1d99ba19a21d57e9f1ed4211a8eeee00e50b7baf/course/format/templates/local/content/section/cmlist.mustache
But here's the challenge. How do I get an object in that format with the data needed to feed the template so it can render the correct CM list items?
Currently I am tring:
$sectionData = get_fast_modinfo($course->id)->get_section_info($section);
But it doesn't seem to return the data structured in the right way.
Any help appreciated.
You can use the function export_for_template of cmlist render class.
Something like this:
$cmlist = new \core_courseformat\output\local\content\section($format, $section);
$data->cmlist = $cmlist->export_for_template($OUTPUT);
and then send the data to the template.
I recommend you imitate the behavior of a moodle as he performs here:
https://github.com/moodle/moodle/blob/7ce003b666a66b465ce9335f430a6e4d3535a7f1/course/format/classes/output/local/content/section.php#L223
I'm using Carbone to generate PDF with variables.
I need to make a conditional display. If a product have a specific category I need to display an information.
I tried to make the condition with ifEQ, show and showBeggin // showEnd but it does'nt work.
// My JSON
const json = {
shopping : {
sales :[
{
product_name: "Apple",
product_price: 2,
product_category: "fruits",
comment: "",
},
{
product_name: "Coke",
product_price: 3,
product_category: "soda",
comment: "",
},
{
product_name: "Cucumber",
product_price: 1.5,
product_category: "vegetable",
comment: "",
},
{
product_name: "Vodka",
product_price: 15,
product_category: "Alcohol",
comment: "Dangerous for health, prohibited at least 18 years old",
},
]
}
}
What I made on my document :
State
{d.shopping.sales[i].product_name} {d.shopping.sales[i].product_category(“Alcohol”):showBeggin} Information {d.shopping.sales[i].comment}, {d.shopping.sales[i].product_price}, {d.shopping.sales[i].produt_name}{d.shopping.sales[i].product_category::showEnd}
{d.shopping.sales[i+1].product_name}
Thank's for help !
Your example got a couple of errors, some fixes to do:
it is missing the ifEQ just before the showBegin
if the ifEQ argument is a string, it must be wrap with single quotes
showBeggin should be written showBegin
the last showEnd should be preceded by only one colon.
Here is your template with all corrections:
State
{d.shopping.sales[i].product_name} {d.shopping.sales[i].product_category:ifEQ('Alcohol'):showBegin}
Information {d.shopping.sales[i].comment}, {d.shopping.sales[i].product_price}, {d.shopping.sales[i].produt_name}{d.shopping.sales[i].product_category:showEnd}
{d.shopping.sales[i+1].product_name}
The conditional block documentation has been improved a lot, to get more examples: https://carbone.io/documentation.html#conditioned-output
Have a great day!
I have a question about creating the custom visualization in Power BI.
I want to implement a "total row" functionality which is available in the built-in matrix visualization. The main concept is to automatically sum-up every value and group it by the rows. This is how it's looks like on the matrix visualization:
But, to be honest, I don't know how to achieve this. I try different things but I can't receive this grouped values in the dataViews.
I tried to analyze the built-in matrix.ts code but it's quite different that the custom visualizations code. I found the customizeQuery method which set the subtotalType property to the rows and columns - I tried to add this in my code but I don't see any difference in the dataViews (I don't found the grouped value).
Currently my capabilities.dataViewMappings is set like this:
dataViewMappings: [
{
conditions: [
{ 'Rows': { max: 3 } }
],
matrix: {
rows: {
for: { in: 'Rows' },
},
values: {
for: { in: 'Values' }
},
},
}
]
Does anyone know how we could achieve this "total row" functionality?
UPDATE 1
I already found the solution: when we implement the customizeQuery method (in the same way as the customizeQuery method in the matrix.ts code), and then add the reference to it in the powerbi.visuals.plugins.[visualisationName+visualisationAddDateEpoch].customizeQuery then it works as expected (I receive in the dataViews[0].matrix.row.root children elements that has the total values from row).
The only problem now is that I don't know exactly how to add correctly this reference to the customizeQuery method. For example the [visualisationName+visualisationAddDateEpoch] is Custom1451458639997, and I don't know what those number will be (I know only the name). I created the code in my visualisation constructor as below (and it's working):
constructor() {
var targetCustomizeQuery = this.constructor.customizeQuery;
var name = this.constructor.name;
for(pluginName in powerbi.visuals.plugins) {
var patt = new RegExp(name + "[0-9]{13}");
if(patt.test(pluginName)) {
powerbi.visuals.plugins[pluginName].customizeQuery = targetCustomizeQuery;
break;
}
}
}
But in my opinion this code is very dirty and inelegant. I want to improve it - what is the correct way to tell the Power BI that we implement the custom customizeQuery method and it should use it?
UPDATE 2
Code from update 1 works only with the Power BI in the web browser (web based). On the Power BI Desktop the customizeQuery method isn't invoked. What is the correct way to tell the Power BI to use our custom customizeQuery method? In the code from PowerBI-visuals repository using PowerBIVisualPlayground we could declare it in the plugin.ts file (in the same way like the matrix visual is done):
export let matrix: IVisualPlugin = {
name: 'matrix',
watermarkKey: 'matrix',
capabilities: capabilities.matrix,
create: () => new Matrix(),
customizeQuery: Matrix.customizeQuery,
getSortableRoles: (visualSortableOptions?: VisualSortableOptions) => Matrix.getSortableRoles(),
};
But, in my opinion, from the Power BI Dev Tools we don't have access to add additional things to this part of code. Any ideas?
It seems you're missing the columns mapping in your capabilities. Take a look at the matrix capabilities (also copied for reference below) and as a first step adopt that structure initially. The matrix calculates the intersection of rows and columns so without the columns in capabilities its doubtful you'll get what you want.
Secondly, in the matrix dataview passed to Update you'll get a 'DataViewMatrixNode' with isSubtotal: true Take a look at the unit tests for matrix to see the structure.
dataViewMappings: [{
conditions: [
{ 'Rows': { max: 0 }, 'Columns': { max: 0 }, 'Values': { min: 1 } },
{ 'Rows': { min: 1 }, 'Columns': { min: 0 }, 'Values': { min: 0 } },
{ 'Rows': { min: 0 }, 'Columns': { min: 1 }, 'Values': { min: 0 } }
],
matrix: {
rows: {
for: { in: 'Rows' },
/* Explicitly override the server data reduction to make it appropriate for matrix. */
dataReductionAlgorithm: { window: { count: 500 } }
},
columns: {
for: { in: 'Columns' },
/* Explicitly override the server data reduction to make it appropriate for matrix. */
dataReductionAlgorithm: { top: { count: 100 } }
},
values: {
for: { in: 'Values' }
}
}
}],
I need some basic assistance with a Highmap (via Highcharts) I am trying to put in my Rails 4 app. I suspect I have some fundamental misunderstanding of it but can't find any clear guidance.
See a simple fiddle taken from the documentation, here
http://jsfiddle.net/SimonWalsh/zpdc1btu/
What I ultimately need to do is provide membership numbers for each country so that it will be displayed much the same as the population density is in this map.
I know I need to provide my data and the means to join it to the map data in
series : [{
data : data,
mapData: Highcharts.maps['custom/world'],
joinBy: ['iso-a2', 'code'],
name: 'Population density',
states: {
hover: {
color: '#BADA55'
}
}
}]
In this example, I am guessing that the data is being pulled from an external source and that the map data is the 'iso-a2' part of the array.
If this is the case, then why can't I supply this with my data....as an example see the added array with my data.....(just one example given for Denmark)
var mydata = [
{
"iso-a2": "dk",
"value": 30
},
]
and then do
series : [{
data : mydata,
mapData: Highcharts.maps['custom/world'],
joinBy: ['iso-a2', 'value'],
name: 'Population density',
states: {
hover: {
color: '#BADA55'
}
}
}]
This does not work.....any guidance at all (other than simply pointing me to docs would be greatly appreciated)
The joinBy specifies on which value you map a country with your data. With
joinBy: ['iso-a2', 'code']
you say that the 'iso-a2' value of the mapData should be equal to the 'code' value of your data. Therefore, your data must have this format:
var mydata = [
{
"code": "dk",
"value": 30
},
/* ... */
]
