Ah I didn’t realize these were timelion visualizations. In this case the problem is that the frequency of your data is too low for the auto interval and there are empty buckets between buckets that contain data. In the default setting timelion doesn’t show a chart in this case. You can fix this by using the “fit” function as described here: Displaying sparse data in Timelion using fit() this will interpolate the empty buckets and still show a chart (without having the problem of creating too many buckets with large date ranges)
