Please follow these instructions to workaround this issue.
MAIN SOLUTION (should work across different Linux distributions; tested on CentOS and Ubuntu 14.04): Use XVFB
You need to install these additional packages on your headless Linux machine: xvfb, libxss1
On Ubuntu Server 14.04 you also need dbus-x11 libnss3 libgconf2-4 libfontconfig libpangocairo-1.0-0 libXcomposite1 libasound2 libxtst6 libcupsmime1 libgtk2.0-0
sudo apt-get install xvfb libxss1 ...
Then you just need to start Omniscope Server through this command:
xvfb-run -a --server-args='-screen 0, 1024x768x24' ./omniscope-server-headless.sh
If this command fails, run xvfb-run with "-e /dev/stdout" option to see the error messages in the console.
e.g. in case of Font error you may need to install these additional packages:
sudo apt-get install -y xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic If you are running the Omniscope Server through Upstart background service, in the visokio-omniscope server installation directory modify the _launch.sh file (last line) from:
"$JAVA_CMD" $JAVA_VM_PARS $ADD_VM_PARS -cp "$JAVA_CP" "$@"to
xvfb-run --server-args='-screen 0, 1024x768x24' "$JAVA_CMD" $JAVA_VM_PARS $ADD_VM_PARS -cp "$JAVA_CP" "$@"Then start the service as usual as per instructions http://www.visokio.com/kb/linux-installs
N.B. xvfb-run seems not compatible with privbind. So if you are using privbind to bind to reserved port (e.g. 80) you need to use an alternative solution: e.g. setting up Linux IPTABLES to redirect port 80 to Omniscope port 8080 see here for reference https://www.frozentux.net/iptables-tutorial/iptables-tutorial.html#REDIRECTTARGET

I have some line charts with measures in the Y axis and dates running along the X axis. Unfortunately, there are a lot of dates, so even with minimum splits width within layout at its lowest setting, the Bar/Line charts don't fit on one screen (only just fits on three by scrolling).
I'd like to be able to demo these charts, and to be able to print them so that they display all on one page (currently if I print I get about 1/3 of it).
Graph views seem more suited to this, but I can't find a way to have two measures overlaid like I do in my attached file (let me know if there's a way).
See the simple attached file to see what I mean.
Thanks

I have tried maximising the view I am interested in so its the only view on the tab, then File > Export to PowerPoint, changing the Advanced settings to get a higher DPI... however, when I print it, it restores the view I maximised to its original size and prints all the views rather than just the one I want. (I hope that makes sense).

Is there a way to automate the export of screenshots in Omniscope? Basically, I have a file where I have pie charts. I want export about 100 different pie charts in png or jpg format to use in presentations. Ideally, I would like to say export the pie chart for all records that match this filter. The pie chart will be different for each individual record, as the underlying data is different, but I won't have to manually export the chart for each record.
I am using the Desktop Edition of Omniscope.]]>
We exported a map in a PDF file and got the result shown in the file attached. The same map was perfectly readable when displayed inside the IOK file (as you can see in the print screen below).
Is there a way to obtain legible values in the round markers in the printed PDF version of the map?
Thanks]]>
From the app top-right "3 dots" menu, by selecting
- Download as PDF, the server will generate and send to client a PDF file containing all the IOK file tabs captured as high quality images page by page.
- Print..., the server will generate a printable HTML report, made of all IOK file tabs high-quality images, that will automatically prompt the end-user native browser print dialog.
Users can select which aspect-ratio to use to generate the PDF or the printable HTML report
When prompted,
- Ticking Use current browser size will generate a report that follows exactly the same app proportions (e.g. views, filters) as seen by the user in their browser.
- Unticking the option will produce a A4 friendly landscape format report, in which the app proportion will be adapted to the A4 ratio.
For instance, iPad users may want to download a PDF that looks exactly the way they are experiencing Server-hosted Omniscope IOK files from inside their iPad browsers by using the Use current browser size option and the result will be something similar to the attached PDF.
N.B. If you run Omniscope Server on Linux server OS and you print a report you may encounter errors / visual glitches, so please follow this troubleshooting post]]>
Is there any way to include page breaks in the table so that when I output the tab to PDF/PowerPoint the sections between each page break are printed? i.e. the table is output to PDF/PowerPoint as however many PDF/PowerPoint slides.. each slide being a different page break section in the table?
Thanks, Ben

I've tried to export it in a PDF file or print it and I'm only able to export o print the upper part of the report (it seems that it's only possible to print or export the first part that fit in the video).
Is there a way to export the whole tab in a PDF (for example in a PDF with more than one page) or print it on more pages? -Thanks

I think this possibility was planned to be implemented in the new version - which leads to the question, when this new version will be released? For good presentations, we have an urgency for the missing features...
Best regards]]>
