I am currently working on report generation using BIRT in KNIME.
I am able to get the chart according to the size and position that I want when clicked on the “view report” button. Example, the image is sitting nicely and neatly in the middle of the page as shown below:
I do not know the specific details of your workflow, but I worked with a sample data set passed into a horizontal bar chart such as yours.
Here is an image of the workflow I used:
Although this does not use BIRT report generation, it is an alternative. For specifically BIRT, I would suggest exporting the bar chart you have as an image using ‘Image to Report (BIRT)’ and customizing the size of the image as it looks like the image on your PDF is oversized.
we improved KNIME Reporting a lot in 5.2, which also includes the Report Template Creator, which is not needed/present in 5.1.
In 5.2, the extension also went from “Labs” to regular status, which is why you will find it under a different category.
I think the reporting extension is already quite flexible with the Text View, Image View, and Generic Echarts View nodes and I personally enjoy using them a lot.
