Can't use nebula xygraph [message #1818923]

I'm trying to use this package.

https://www.eclipse.org/nebula/widgets/visualization/html/GettingStarted.html

On this site it is listed which jars I need to import and I have found them looking around with google. The org.csstudio.swt.xygraph.jar was from 2012 but it was all I found.

org.eclipse.draw2d.jar I found by searching around the internet. And the others in the nebula folder from eclipse.

First, it all seems like a mess, having to search for jars with google, are they not located in eclipse somewhere?

I tried to add software sites but I just don't find these preferences in eclipse.:

Can someone please help me? I just want to be able make plots.

The "Pure Java" jars it lists are missing version numbers; ALL of them should be installable from http://download.eclipse.org/releases/latest, after which the "these jar files are generally available with your eclipse installation under eclipse/plugins folder" will be true. You might need to uncheck the Group Items by Category option to find some of them, or else pull them down using the P2 Director CLI: https://wiki.eclipse.org/Equinox/p2/Director_application .

https://help.eclipse.org/2019-12/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/p2_director.html should work. I'll update the wiki page.

You can use these instructions to find Eclipse update sites:

https://wiki.eclipse.org/Eclipse_Oomph_Authoring#How_to_find_a_P2_repository_at_Eclipse_using_the_Repository_Explorer

E.g., this update site includes that bundle:

http://download.eclipse.org/nebula/snapshot

And you can look at all their update sites starting from:

https://download.eclipse.org/nebula/

I have already installed that bundle, but I still get missing classes, these are not found, they are from an example.

import org.eclipse.nebula.visualization.xygraph.figures.ZoomType;
import org.eclipse.nebula.visualization.xygraph.figures.Trace.BaseLine;
import org.eclipse.nebula.visualization.xygraph.figures.Trace.ErrorBarType;
import org.eclipse.nebula.visualization.xygraph.figures.Trace.PointStyle;
import org.eclipse.nebula.visualization.xygraph.figures.Trace.TraceType;
import org.eclipse.nebula.visualization.xygraph.linearscale.AbstractScale.LabelSide;

All other classes in the example are found. I am trying to run this example:

https://raw.githubusercontent.com/eclipse/nebula/master/examples/org.eclipse.nebula.snippets/src/org/eclipse/nebula/snippets/visualization/ComprehensiveExample.java

I have this installed (and others) but this should be the relevant one:
org.eclipse.nebula.visualization.xygraph

Installing the plugin doesn't put it on the classpath. Is this a plain Java project or a Plug-in project that your working on? What you have done so far to ensure the jars for the imported packages are on the classpath.

BTW, I assume you downloaded https://www.eclipse.org/downloads/download.php?file=/oomph/epp/2019-12/R/eclipse-inst-linux64.tar.gz and that works for me on Ubuntu...

I installed them from the 'install new software' dialogue

then I added them to the 'java build path' under 'projects'

I also added external jars which I downloaded, I also tried only one of the methods at a time.

adding external jars worked well for swtchart
