Vizlib Filter Properties - Dimensions, Data Handling

In the property panel, the Dimensions menu is where you define your filter field, which can be a single dimension, a drilldown or a master item dimension. In this example the values in the Clothing table are filtered against CategoryName, and you select, deselect and display them in the Sales YTD Mini Charts (Figure 1). You can find an example filter setup in our guide here

You can also select to display a Frequency Count for the dimension (Figure 4), choosing from the Absolute value, Percent or Relative value. Figure 5 shows the frequency count as a Percent with 8 Categories representing 12.5% each of the available values.

The Indicators settings allow you to display an indicator next to the measure (Figure 7), and also customize the indicator shown when the measure is compared to a pre-defined threshold. You can enter the value in Indicator Threshold (this example sets the threshold at =20/100 or 0.2).

The icon and color indicators (Figure 8) can now be set, and they are displayed according to the result of comparing the measure value to the threshold (Greater than, Less than, Equal than). You can choose to show or hide each icon, and also set the Icon Position
