Scheduling results in PDF look to be incomplete

Problem:
Recently (post-upgrade to 8.0.x) we have noticed that some of the line chart panes in a scheduled dashboard are missing the second half of data points in the subscription email PDF. When we run it manually and export it manually, we don’t see any issues.

Cause:
This may be due to the PDF being generated before the animation is complete for the line chart.

Solution:
Please try to turn off the animations using below two properties to see if it helps:

plotOptions.series.animation: false
plotOptions.line.animation: false

If you are using a JRXML report, you can set these properties by editing the HTML5 chart > Chart Formatting > Show Advanced Properties, and then expand plotOption > series > animation and set this to false. Similarly, we need to do this for plotOptions.line.animation: false

If you are using an Ad Hoc View these properties can be set under the Advanced section of the Format Visualization tab.
