Exception issue with creating aggregate graphics through aggregate templates.

[wyy941013]

The aggregation graph created by the aggregation template gives an error, which is normal when I unassociate with the aggregation template. After debugging the graph, I found that there are some redundant cdef. Please help me troubleshoot the problem. thanks

1. This is the aggregated graphic template I created through the graphic template.

2. This is the rrd debug information for the aggregated graph.I found that there were obviously empty'cdefs', which I thought should not be expected.I don't have a clue to solve this problem.

3. This is my aggregated graphic information.

4. I have two Cacti servers with the same environment configuration, and the other one is normal.

This is my update from v1.2.25 to v1.2.30. After I manually handled the 95 peak billing calculation fix, I was left with this problem.

5. When I tried to cancel the spread, it was normal again.
