Is there an efficient way to generate a histogram of dates (time stamps) in Knime? The histogram node doesn’t accept dates as input. As a work around, I can think of two inefficient approaches: Use Date&Time to String node followed by a group by count and bar plot. The problem with this is that I am limited to monthly or yearly bin ranges. Use Python View node (works great, but it’s not KNIME).

Hello @jnicolich I think that you’ve summarized the options quite well; besides you didn’t mention R along with Python. What I don’t agree about your first option is the limitation on monthly / yearly… once it’s defined as string, it can be any other (weeks…) BR

@jnicolich here is a line chart with dates on the x axis. Maybe you can provide sample data and maybe a sample for a graphic you want.
