How can I make an broken line on the chart in QlikVeiw?

[ivan_slobodian]

I have months sales data by a lot of objects.

For example, in june 2018 we have not sales for one object. It isn't zero meaning, it is missing value. That is why sales dynamic from may to july 2018 should not be connected by line on the chart.

[pradosh_thakur]

if you want it be zero then

use alt(measure_field,0) as measure_field
or
if(len(trim(measure_field))=0,0,measure_field) as measure_field

then use it in the chart

You should use background color property for expressions to hide missing parts.
