Hi Jan!
First off, your Power BI Box-Whisker Plot visualization is stellar. Great work!
My team is trying to use this visualization against a relatively small dataset (20 columns with 1,400 rows), however, we are getting an error stating the data set is too large.
Being the curious guy I am, I jumped into the code and noticed that it's using the passed in dataView.matrix to populate your data points and categories #L353. What caught my eye with this line though is that the Categories are populated from the rows property and not the columns.
I am not an expert on TypeScript or Power BI visualizations and may be missing something that's obvious, but shouldn't it be the opposite to avoid any column count limitations with the underlying matrix? I would think that the Categories should run across, not down in the dataset.
When we create a matrix in Power BI against the same dataset and flip the axis, we receive the same error message.
