Grid Chart Sense KPI Extension

Proud to announce I’m publishing my first Qlik Sense extension. Is it a grid chart or a waffle chart? https://github.com/RichardPearce60/sense-svg-grid-chart This isn’t my first extension, over the past few years I’ve been enhancing my web language experience learning JavaScript and several library’s (D3, require, angular, lodash, etc). I took my inspiration for this chart from one I saw on the BBC news website. The concept is simple enough and the idea of such a chart is to give more cognisant representation of the data. In the example above we can see how many cars in 100 are in an accident ..read more

Rounding D3 Scale Values in JavaScript

D3 Scales make creating chart axis simple by passing the extent (min / max) values to the scale.domain. Unfortuanly our values mean axis extremes aren’t always “nice”, they are absolute and not rounding. Not always a problem but can lead to an ugly ugly chart. For example lets say our min / max values are 14 and 72. Our D3 axis would compute as follows. If we were to add the .nice() parameter when we construct the scale we get something a little better. Its still the same date, just rounded of for the purpose of the scales. This is great but you’re still at the mercy of D3.scale.nice functio ..read more

Qlik Sense mashups can be quite simple at first. The dev hub lets you create the files you need, connect to and app and drop in charts. Here’s a simple example on how load three charts (hide two) then toggle between them using CSS and JavaScript. <!doctype html> <html><head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <title>Qlik Sense Mashup</title> <meta charset="utf-8"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <meta name="HandheldFriendly" content="True ..read more

Measure distance in km between two map coordinates

Firstly I’m not a math whiz. What I’ve done here is take a JavaScript function, convert it to Qlik Sense script code and test it works. The problem… I have two latitude (lat) and longitude (long) coordinates and I wanted to calculate distance between the two as the crow fly’s in km’s. Using google maps I can pick two points, record their coordinates and measure the distance so I know what I’m aiming for. In this example I’m heading from my home to my office (not done that since lockdown) and the magic number is 34.3 km’s Here I find a solution to the problem, the JavaScript code is easy to fol ..read more

D3 Network Chart (early development)
qlikcentral
by Richard Pearce
3y ago
The Challenge Most company’s have work flow processes where a piece of work is passed from department to department step by step until its marked as completed. Some processes are well defined, ridged and are simple to map out and others take on a more random path depending on their unique requirements, sometimes looping around the same department several times before it can be marked complete. Ideally I would have loved to work with a defined process where I could map data onto clear info-graphs (see below), perhaps the project will lead there, but for now I’m working with dynamic data.

Do you still script directly in Sense?
qlikcentral
by Richard Pearce

Why wouldn’t you? Qlik has its own editor accessed through a browser which works well. You’re script is colour coded, auto completions are suggested and you can organise your code into tabs. So why use a text editor made by a third party? Well if you’re working with multiple developers (especially across geographical locations) and you’re promoting your work through multiple Qlik server clusters (for example: Dev, UAT, QA, Prod) then you may want to consider changing your development tool. Choice of Editor These are programs you download and install separately to Qlik, most are free and you o ..read more
