<p>Hi All,<br>
</p>
<p>My Setup:</p>
<ol>
<li>Lizmap 3.4.0</li>
<li>QGIS Server 3.16</li>
<li>All on Linux Server (not sure which one, offsite)</li>
<li>All spatial and table data in PosgreSQL<br>
</li>
</ol>
<p>I had a Dataviz set up with a bar chart for monthly rainfall [mm]
to display in the popup by clicking on a rainfall station on the
map. First I only had 3 sites which worked fine. Then I added
another four sites and now the chart header briefly flashes and
disappears again.</p>
<p>The rainfall station table is the master and the rainfall
readings are in a detail table (1-N) with 4 fields...ID, site_id,
date, reading and the relation set up with the Rainfall station
table's site_id. The readings are 1 per month (monthly rainfall),
so in Dataviz the X is the date field and the Y is the reading
field. There are about 3700 readings (about 400 to 700 per site).
Is there any limitation on that? Why did it work with 3 sites and
not with the seven? But now even when reverting to the 3 sites it
does not work any more. Is that a cache problem? The detail table
with the rainfall readings is ticked in the WFS QGIS Server setup
and the whole project is valid.<br>
</p>
<p>It seems to be a problem with the relation (maybe???), but in
QGIS info tool the relations show fine (the detail data is there).</p>
<p>This is quite frustrating.</p>
<p>Regards<br>
</p>
