Vizlib Sankey Chart Best Practice and Troubleshooting

When you're working with Vizlib Sankey Chart it's important to be clear about what you can and can't do. We've collected together some tips for best practice, known issues and limitations and listed them in this article for you, along with any answers to any other questions you might need.


TABLE OF CONTENTS


Best Practice


  • Let's introduce you - If you're new to Vizlib Sankey Chart, or looking to find some information, the Introduction page has links to the product resources and knowledge base articles.
  • Work with the wizard - Always use the Setup Wizard to start building a sankey chart, you can always add expressions or edit data in the property panel once you have the basic version.
  • There is an alternative - Vizlib Sankey Chart can be used with alternative dimensions and measures. If you add alternatives, you'll be able to choose the measure you prefer when the sankey chart is in analysis mode, changing the outcome of the chart for a much more adaptable and varied used experience.
  • Viztips - Viztips is a very powerful tool to add to any extension, but you can only start using it with some preparation. Make sure the visualization using Viztips is set up with the dimensions and measures to give you the result you want, and has the set analysis you need. 
  • Performance - Vizlib Sankey Chart uses the Qlik Sense hub engine, and each individual value will be processed separately. If you're working with very large amounts of data in your sankey chart, this will affect the Qlik Sense engine processing time and performance may become slower. You can find more information in our article on Best Practice and Performance Optimization in Qlik Sense.
