gnuplot is not exist in http://dl-3.alpinelinux.org/alpine/edge/testing/

Resolved using gnuplot 4.6 from --repository http://dl-3.alpinelinux.org/alpine/v3.0/testing

[mesros]

Repository http://dl-3.alpinelinux.org/alpine/edge/community/ works but gunplot does not. The following error is provided using the opentsdb gui:

[id: 0xf0fcfc58, /172.25.10.45:60085 => /172.17.0.2:4242] Bad Request on /q?start=2017/04/28-00:00:00&ignore=6&m=sum:IMEF01FA1148R%7Bapplication=asdp%7D&o=&yrange=%5B0:%5D&wxh=1900x779&style=linespoint&json:

Gnuplot stderr:

@jetgeng Did you had the same issue? If yes how did you resolved it?

I'm updating the dockerfile to pull gnuplot from this repository. Thanks for the suggestion @mesros!

[PeterGrace]

I'm reopening this since I used the repository as suggested by @mesros but still have the same gnuplot rendering error. I'd like to figure out this issue but I don't want it to prevent my other updates to the repository, so I'll see about fixing it at a future point.

What seems to happen is that the gnuplot 5.x from Alpine does not has built-in support for terminal 'png', only supports 'pngcairo' which does not have the option to set the size:

• Manual page for pngcairo version 5
• Manual page for png version 5

The log from the gnuplot build that can be found here shows that libgd-png based terminal is not integrated in gnuplot.

I tried to build locally and seems that libwebp-dev installation is missing for the configure script to enable the png terminal.

As possible solutions, or the Alpine distro maintainers add the libwebp-dev as a dependency to build gnuplot or gnuplot has to be built from scratch in the Dockerfile.

I am having the same issue:

@PeterGrace can you verify the PR and merge it? if it fixes the problem.

[PeterGrace]

Sorry for the delay and thanks for the ping @hardikaurea -- github notifications notoriously go missing for me so pinging me is the best way to get my attention. I merged the PR as it does definitely resolve the issue.
