Weird broken graph?

[cliffcampbell]

Trying to show a running total of something and I end up with this graph that it split in half? The data seems to be correct if I mouse over.

I’m using

SELECT created_at as time, sum(count(*)) OVER (ORDER BY created_at)
FROM table
GROUP BY created_at;

You probably wanna add WHERE $__timeFilter(created_at) to your query to only query data for your selected timerange or increase the timerange so all returned values are displayed
