Configuring the display of null values in a Yandex DataLens chart

If the source data includes a row where the measure value is null, the chart with default settings connects the neighboring points with values other than null with a line.

You can configure how the chart will display null values in the chart section settings:

1. Click in the top-right corner of the section with the measure you want to configure (the icon appears on hover).

2. Set up the Null values option:

   • Hide: Do not show points with null values. On the chart, it will appear as a line gap, skipped column or point. For example, the source has a row with a date (20.07.2022) but the sales total for it is not specified.

     Example of a chart with a gap

     

     Source table

     OrderDate	Sales
     15.07.2022	301629
     16.07.2022	453595
     17.07.2022	977583
     18.07.2022	527834
     19.07.2022	870054
     20.07.2022	null
     21.07.2022	569650
     22.07.2022	1116034
     23.07.2022	883208
     24.07.2022	2359483
     25.07.2022	1137851

   • Connect: Connect neighboring points with values other than null with a line.

   • Display as 0: Replace null values with 0.

3. Click Apply.

If a row is missing from the source data altogether, the Null values option will not change the way the chart is presented. For example, if the source does not have a row with a particular date (20.07.2022), nothing will be shown for this date on the chart.
