There is a multitude of different libraries for charting in Javascript.
This issue (based on current information) will focus primarily on plotly.js, d3 and vega.

This blogpost mentions the problems that occur with the SWT browser widget and different operating systems.

To fix these problems, there is the mentioned plugin for eclipse that uses an underlying chromium instance to render the webpage.

This should work for the different operating systems uniformly.

The problem that occurred during testing was, that it was only possible to get the chromium browser to run successfully under Eclipse Photon, due to missing plugins in older (Oxygen) Eclipse versions.

Writing to JSON (HTML, JSON and CSV) and opening it in the browser, parallel to the SLR-Toolkit session.

Basic implementation of the diagram types vertical bar chart and bubble matrix chart in the chosen javascript library.

For using the default browser for the SWT browser widget there is the problem that it will use different browsers to render the webpage. Under Windows the default browser is Internet Explorer, in linux there is no default and Mac OS uses WebKit. (Source)

It did not work out of the box for linux. After some struggle it was possible to get a renderer to run (xulrunner 24.0b10), one of the recommended versions. A problem with this is, however, that the newer versions of xulrunner didn't work and the last stable release is from 2015. In July 2015, Mozilla announced that it will not keep on working with xulrunner.

It seems, that only using the older versions of xulrunner will work under linux, and it might not be supported any more in newer instances.

Task:

Renew the graphing of the taxonomies in the SLR-Toolkit.

Requirements for finishing the project:

• new charting with longer support
• bar chart and bubble matrix chart
• export of the graph as SVG
• export of the taxonomy data as CSV
• newer and fresher design
• bubble labels for the bubble chart
• legend for the bubble chart
• color for the bubble chart
• color bubble chart default to gray with black border
• hint for incorrect amount of taxonomy values (tooltip/disable enable button?)
• refactor (take out the original charting)
• check for windows and make a release
• create a pull request
• data concept?

Exporting the graphs and diagrams to pdf or svg is one of the major requirements for this project.

Since some of the graphing libraries only offer this in premium versions, a workaround might be to export the graph directly from the canvas that draws it.

This issue tracks the documentation and progress on this matter.

Might be irrelevant, if the graphing library supports a clean export.
