Qlik Sense 2 Dimension Stacked Bar Chart

[#1]

New to Sense...

Have a Stacked bar chart with 2 dimensions and 1 expression

Dimension 1 is hour, Dimension 2 is ID

The top portion of the stacked bars contains a grey "striped" section (see attached).

Can you help me understand what I am seeing here and perhaps how to remove (if appropriate)

Thank You

Hi,

Exceeding the numbers of values graphically representable for your DIM2 dimension ?

You can test i by add a lot of new value and see what happens.

Hi Glenn,

These are most likely null or blank values in DIM2.  You can suppress these by editing the chart and on the right hand pane under data then DIM2 uncheck the box "Show null values".

Hope this helps.
