Vizlib Flow Chart Properties- Dimensions, Measures, Sorting, Data Handling

Vizlib Flow Chart supports one measure with multiple dimensions. You can add dimensions or metrics dynamically and decide whether they should be used directly or added as alternative dimensions, which can be selected when you're in analysis mode. 



When you add a dimension (Figure 1), you can set the Field and Label, and choose to Include null values. Calc. condition gives you the ability to specify a conditional expression which shows or hides the dimension in the flow chart. 

Node Color specifies a color for the dimension, and you can also specify the color using a HEX code in a Qlik expression (not shown here). You can also display the dimension label by enabling Node Label and display the measure value for the dimension nodes with Node Value.

You can also set a Data Downloading limit (by default, this is limited to the first 5000 rows), choose to Suppress Zero Values and set a Calculation Condition to display the chart if a condition is met (Figure 6).
