Qlik Sense Path Sankey Extension

Single Dimension Entry:

There are many areas of data we work with that involve a series of events over time. In the online world it may involve clicking on web pages. In healthcare it might involve a series of surgical events or procedures. Thus for the sake of simplicity I simply chose the values "Event1" "Event2" etc.

Assume the following in your load script: Data: Load * Inline [ ID, Path 1, 'Event1, Event2, Event3' 2, 'Event1, Event2, Event4' 3, 'Event1, Event3, Event4, Event5, Event6' 4, 'Event2, Event3, Event4, Event5' 5, 'Event2, Event3, Event5, Event6' 6, 'Event2, Event3, Event5, Event6' 7, 'Event2, Event4, Event5, Event4, Event5' 8, 'Event1, Event2, Event4' 9, 'Event3, Event6, Event9' 10, 'Event3, Event6, Event9, Event10' 11, 'Event3, Event6, Event9' 12, 'Event3, Event6, Event9' 13, 'Event3, Event6, Event9' 14, 'Event4, Event10, Event11' ];

Setting a single Dimension to your field "Path" and using a measure of "Count(ID)" will yield the following output:

There are also many areas of data where analysis of relationships is also important to understand. Pie charts are great for comparing single dimesnions. But this sankey can also be used to show relationships between dimensions so you understand how they relate to each other.

Assume the following data in the load script: data2: Load * Inline [ ID2, Field1, Field2, Field3 1, Male, Blue, Zip1 2, Male, Brown, Zip2 3, Male, Green, Zip2 4, Female, Blue, Zip2 5, Female, Blue, Zip3 6, Female, Blue, Zip3 7, Female, Green, Zip1 8, Female, Brown, Zip2 9, Male, Hazel, Zip3 10, Female, Green, Zip2 11, Female, Blue, Zip3 ];

Setting a single dimension to a concatentation of the fields like "=Field1 & ', ' & Field2 & ', '& Field3 & '," and using a measure of "Count(ID2) will yield the following output. Notice that like a pie chart you can tell that there are more Females than Male. More importantly you can tell that the majority of Blue eyed people are Female rather than male. While also seeing the overall comparison like a pie chart between the color of eyes.

You can create the same effect to view the relationships between fields by simply using multiple Dimensions:

The important parts of code that you might want to change if you find yourself in an environment that has more than 100 unique values for any dimensional value is going to be in the PathSankey.js file. You will find the following segment of code and can simply adjust the qHeight value as needed.

qInitialDataFetch: [{ qWidth: 5, qHeight: 100 }]

If you find yourself in an environment with data for a path and they did not use commas "," to separate the values there are several points of code where you can change to utilize whatever separator character you may need to use.

Areas like: sep = ","; And: var tArr = path.split(",");
