Report Writer: SVG Unsupported in Report

[mwiegand]

Hi,

due to the lack of support of negative values by some chart nodes, I had to resort to using the Bar Chart (JavaScript) node. The node generates an SVG, which I personally prefer over PNG for a multitude of reasons,. Though, SVG is not supported in both, the PDF and HTML Report Writer.

The issue about displaying negative values is not addressed yet.

Chart Node: Contains both negative and positive values are not displayed

Hi, while working on the current Knime Data Challenege I calculated the change YoY and noticed the Stacked Area Chart complains about columns both containing positive and negative values. Consequentially, it stated they cannot be displayed. WARNING The selected frequency dimension United Arab Emirates contains both negative and positive values. It is thus not displayed. Though, as seen in the screenshot below, pretty much all have values fluctuating between positive and negative and are sti…

Anyways, SVG support might be (hopefully) implemented:

Generate SVG images for improved Rendering and potentially adding Interactivity

Hi, I’d like to suggest to generate SVG files instead of PNG. If a PDF or HTML report is generated and multiple images are positioned alongside each other, SVG would allow to zoom in while PNG would be barely readable. Since there are several libraries available which add interactivity to SVG charts, it would also be a great future feature providing interactive HTML-Reports. Best Mike

Hi @mwiegand,

it is not so much that the Report writers do not support SVG, but that the Reporting does not support the old JavaScript views (and also no interactive widgets).
This is why it prints “This view is not supported” and not “Rendering SVG is not supported”.

Once the new views generate SVGs, which is actively being worked on (your second forum link), you will find they will be included in the report output and look as crisp as you would expect scalable graphics to look.
