Hello, when I print a Pie Chart in a PDF, there is no text, either for the legend, or for the "pie slice" percentages.

Any suggestions?





Example of a pie chart from a PDF:

The most basic information is missing: Which LS version? Without that, it will be very difficult to reproduce.

Forgot...

Version 3.7.1+180424
Chrome Browser
Ubuntu 16.04 installation

Also, here's what I get when I hover over the pie chart.

Got the same problem here, did you solve it?

Version: 3.14.5

I did some changes in the code and now I can show the legend, but they're wrong and still no percentage in any slice.


Edit: the legend isn't wrong but I would like to show the question text in the place of the numbers.

Edit2: I just figure out how to make the percentages work, in limesurvey\application\helpers\admin\statistics_helper.php where the 3D pie chart is created the "setFontProprieties" was poiting to '$rootdir."/fonts/".$chartfontfile', but the fonts are in '$rootdir."/assets/fonts/".$chartfontfile'. Now I just need to change te text.

Just a question, the option "graph type" was supposed to work just when i select html format or for pdf too? Because it doesn't, the graph type shown is the one i've set when creating the question.

Update to the latest version, see if the problem persists. If it persists: make a bug report. Your changes might be overwritten by any future update you might make, so I think it is best that it is fixed in the core, rather than you hacking the code. Might be a temporary solution, but is not future proof.

So a year later I still have the same issue! Thankfully, I found the problem, and set up a workaround.

ISSUE: PDF legends on pie graphs and other graphs have no text. I found the problem by setting debug to "2" in the config.php file. This showed a number of PHP warnings linked to pChart.class.php and specifically a link to a missing file found along the path /HOMEDIR/fonts/DejaVuSans.ttf. It turns out that there is no fonts folder in this location, but there is one along the path /HOMEDIR/assets/fonts/DejaVuSans.ttf. I'm guessing this is because I have upgraded (properly) a number of times, and somehow the MySQL database still has a reference to the old path.

WORK AROUND: For now, I just created a symbolic link so that /fonts points to /assets/fonts. At some later date, perhaps I'll track down the error in the database.

NOTE: This seems somehow related to this bug report: bugs.limesurvey.org/view.php?id=13338
