Hey everyone!
I am learning knime in the past few days, it’s great but I still hit my head very hard here and there on how to decypher the answer he gives me during my workflow building.
Particularly, I have been stuck since morning with this problem:
I have a huge dataset sampled every second and want to plot it (line, scatter, whatever) in a specific range, user defined OUTSIDE the ploting node.
E.g.: Through a couple of “date&time input” interactive windows, the user choose a “begin” and an “end” date, these are given as flow variable to the plotting node (xAxisMin and xAxisMax), which should “zoom” or just plot within that interval
Result:
– Errors loading flow variables into node : Coding issue: For input string: “2019-03-14T08:51:08+01:00[Europe/Berlin]” –
After several experiments, I noticed that this two variables are taken as String and, in case you have a numeric axis (Integer or Double), that works like a charm. The problem is specific with date&time axis.
I supppose that, just like with numeric, knime reverts even date&time in some sort of numeric format and then plots it (similar to what excel does?). I just can’t figure out the conversion formula.
Clues/Suggestions?? I also tried “range sllider filter definition” but it only takes Doubles.
Thanks Everyone!
