Hi,

Are the trendlines appearing in the legend?

Is it possible the trend line is beyond any scaling limits you may have set?

Cheers

I have four identical charts looking at very similar data, three series per
XY chart. I want trendlines (moving average) on all data series of all
charts. One chart will not show any, others will show all three, some will
show some but not all. No error messages, go through procedure of adding
trendline, but it just doesn't show up. Search for hidden line with cursor,
doesn't show.
