Using range filters

The range filter lets you filter to a range of values using a slider.

About this task



You can filter out values at both ends of the range, meaning that only rows with values within the chosen range remain in the visualization. Labels above the slider state the exact range.
Note: A shade at either end of the slider indicates that currently there is no data visible in that part of the range because other filters in the analysis have filtered out those rows.
Range filter with values filtered using other filters

Double-click on the colored part to adjust the filter to only show the effective range.

An important feature of the range filter is that the values are distributed on a linear scale according to the values of the data. Thus, if values are unevenly distributed, this will be reflected in the range filter. Note that this is not the case with item filters, where values are distributed at even intervals along the range of the slider, regardless of the actual numeric values.

Procedure

  1. Drag the left and right slider handles to change the lower and upper limits of the range.

    If the range slider shows dates you can also click on the calendar icon to set start and end dates.

  2. Alternatively, double-click on a label, type the wanted end value, and press Enter.

    The labels show the lower and upper value of the range.

Moving the selected range sideways

The currently selected interval of the range filter can be grabbed and moved to pan the selected range - this provides a powerful way of sweeping over different "slices" of a data table. Click and drag the blue portion of the modified range slider to do this. Observing the reactions of the other sliders to such a sweep can give some interesting clues to correlation between parameters in the data table.
