I am running GitHub - sdr-enthusiasts/docker-piaware: Multi-arch PiAware docker container including support for bladeRF, RTLSDR, SoapySDR. Includes dump1090 & dump978 (amd64, arm/v6, arm/v7, arm64v8) available at https://pi.scientificdatasystems.co.uk/ if anyone wants to have a look
I am guessing it’s a config issue but I don’t know what to look for
It looks fine to me.
It looks like your browser window has truncated the right hand side of the screen.
Thanks for replying. It’s all working fine, but notice in the bottom left of the map there is a white rectangle, which I believe is meant to have a coloured altitude legend. I want to either remove the rectangle as it is, or get the chart legend thing to work 
Ah, yes, I see what you mean now.
It should look like this.
It looks like the image file is not readable on your system.
/images/alt_legend_feet.svg
In a normal installation it is in:
/usr/share/skyaware/html/images
It does seem to exist at https://pi.scientificdatasystems.co.uk/skyaware/images/alt_legend_feet.svg
Sorted
Fix:
edit file /etc/lighttpd/skyaware.lighttpd.conf
add an entry for ".svg" like so:
# mimetype mapping
mimetype.assign = (
".svg" => "image/svg+xml",
".pdf" => "application/pdf",
".sig" => "application/pgp-signature",
...
then restart
