Bug ID: 152462
Summary: Trend Lines do not get created correctly if a dataset
is re-ordered by sorting the table.
Product: LibreOffice
Version: 7.4.3.2 release

Status: UNCONFIRMED

Trendline on a graph where the original data was then sorted by a different
column
Trend Lines appear to be created from raw table data so appear as a childlike
scribble if table is re-sorted (graph is correct still though). It's very
artistic looking, but totally useless.
This has been broken since at least version 7.3 and I think well before.
I've attached an image showing a 14 point moving average on a roughly 200
datapoint bar chart style graph to demonstrate the problem.
If you resort into natural order again, then the trendline is correctly drawn
hence my theory that the trendline is being drawn from the original table data
rather than that used for rendering the graph.
