Best Practice

  • Performance
    • The chart uses the Qlik Sense hub engine, and each value will be processed separately. We can find more information in our Best Practices and Performance Optimization article in Qlik Sense.
    • Forecasting has different modes and can be 'trained' on a defined number of data points within your Vizlib Line Chart. Please note that using more points as the trainer and forecasting more points takes longer.
  • 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.

Known issues

  • Tooltips
    • Tooltips are disabled when the second dimension is displayed in a donut or pie format.
  • CJK characters
    • For Y-Axis titles, the text was flipped. This has been fixed to inverse the text axis and was released in the version v5.0.3. Please see the here: Vizlib Line Chart V5.0.3.


  • There are currently no limitations

Tech Understanding

  • Forecasting
    • The Vizlib Line Chart (and any other product that uses forecasting) uses this formula to define ARIMA standards for forecasting. You can learn more here:
    • Vizlib recommends doing tests with a subset of your data and forecasting the remaining amount to them compare with your full data set used within the Vizlib Line Chart.
