Vizlib Line Chart Best Practice and Troubleshooting

When you're working with Vizlib Line 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.


Best Practice

  • Let's introduce you - If you're new to Vizlib Line Chart, or looking to find some information, the Introduction page has links to the product resources and knowledge base articles.
  • Analyse This? - Vizlib Line Chart is designed to be used for trend or distribution analysis. If your data doesn't fall into those categories, another chart extension might be a better fit. 
  • Work with the wizard - Always use the Setup Wizard to start building a line chart, you can always add expressions or edit data in the property panel once you have the basic version.
  • Forecasts and Predictions - If you'd like to use analytics forecasting in your line chart, we've got an article on Advanced Analytics to help you understand and apply it without any coding or extra installations.
  • There is an alternative - Vizlib Line Chart can be used with alternative dimensions and measures. If you add alternatives, you'll be able to choose the measure you prefer when you're using analysis mode, changing the outcome of the chart for a much more adaptable and varied used experience. If you'd like to add more focus to your chart, look at adding reference lines to help users analyze the chart data.
  • Performance - Vizlib Line Chart runs using the Qlik Sense hub engine, and each individual value will be processed separately. Having defined settings for related values (e.g. grouping color settings) will reduce Qlik Sense engine processing time so this may help if you feel there's an issue with the chart performance. We've compiled some general advice about improving performance in Qlik Sense here.
