Data

Sorting

In Property Panel > Sorting, you can define how the software orders data in the application.

Data handling

In Property Panel > Data handling, you can decide how much data the software loads into your Qlik app and how many records are displayed. With the Data downloading property, you can choose the following options:

  • Initial loading - the software loads first 1000 records.

  • Define max records manually.

  • All data.

For optimum performance, insightsoftware recommends you choose the Initial loading option.

Advanced Analytics

In Property Panel > Advanced Analytics, you can configure features that enable users to perform advanced data analysis. The following features are available:

  • Ignore selection in calculation (On/Off) - available in Property Panel > Advanced Analytics > Calculations. This property defines how the software calculates the average (Avg), upper control limit (UCL) and lower control limit (LCL) when a user makes a selection on the chart. When the property is set to Off, the software calculates Avg, UCL, and LCL based only on the selection, ignoring unselected data. When this property is set to On, the software calculates Avg, UCL and LCL against the entire dataset.

  • Runs (On/Off) - Available in Property Panel > Runs and trends. Runs are consecutive data points on the chart that are on the same side of the Avg. You can use the Run length property to define the minimum number of points that the software highlights as runs.
