Null and missing values in charts
You can now choose how null and missing date values appear in line, line column, line stacked column, column, and bar charts in ThoughtSpot. From the Chart configuration menu 
for the date column, you can decide to show or hide null values in column, line, and bar charts. You can also decide how to display missing date values from the Chart configuration menu for each measure column.
Previously, ThoughtSpot displayed null, missing, and zero values as empty spaces on bar and column charts. To make it easier to identify null and zero values, you can now choose to display null and zero values as bars of 1 pixel width on bar and column charts. Missing values appear as blank spaces.

-

Choose how to display missing values for line charts
You can choose whether to display missing date values as zero values, line breaks, or an average of proximate values on a line, line column, or line stacked column chart. Rather than showing a sharp decline to zero every time there is null or missing data on your line chart, you can see the missing values represented as line breaks or interpolations of the closest values instead.
