With the August 2018 release it's possible to assign a data category to a measure, this allows to make a measure representing an svg chart
For additional details on the method, please see this post on the DataVeld blog
or my own post about this microchart.
Both visual types the circular "Harveyball" and angled "Harveybox" are basically comparing two percentages. The Harveyball visual can also be used with just one circle, or better just a segement an arc.
Everything is controlled with two of measures
Replace the calculation with your own calculation and make sure that the measure returns a value >= 0 and <= 1. I tried my best to take some precautions that all other input are treated as an error.
This means that you need to copy four measures from the pbix file to your own model
After the above mentioned preparations the measures "Harveyball" and/or "Harveybox" can be used inside the table or matrix visual.
The measures "Measure Achievement" and "Measure Effort" also provide an "input parameters" here you can configure the color (provide HEX codes) and also if you want to show an element of the visua. The input section looks for the measure "Harveyball" looks like this:
// input parameters // Background Circle: represents percentage of current achievements (100% means everything is done) var ShowBackGrndCircle = TRUE() var BackGrndPercent = [Measure Achievement] // value has to be >= 0 and <=1// using Firefox one has to use "%23" instead of the "#"-sign var BackGrndColor = "#D9D9D9" //D9D9D9 // Front Circle: represents effort spent for the current achievements in percent of available ressources (100% means there are no more ressources available) var ShowFrontCircle = TRUE() var FrontPercent = [Measure Effort] // value has to be >= 0 and <=1 var FrontColorGood = "#68CDFE" //68CDFE var FrontColorBad = "#E86232" //E86232 // Show text below the circles var ShowText = FALSE() var HarveyBallSubtitle = "a measure" //replace the string by a value or string that will be printed
Basically the filled arcs and also the polygons of the Harveybox are drawn by using the path element.
I wish you all a lot of fun using this kind of visual.
I notice that the SVG files presented inside a table row in this demo and every other example of using SVG are always square (i.e. have a ratio of 1:1). I understand this is a restriction on Power BI table matrix.
Do you know if there is a way around this restriction? Or do you know if the problem will be fixed in Power BI?
