QUESTION
I would like to call onDataChange() only if previous value of input / selection != current Value of input / selection.
However I've noticed that it is still calling onDataChange() whenever put the cursor on the input field (but didn't change any value of the input field / change selection of the dropdown value).
I have used startWith(null), pairwise, and then filter(prev!=next) but it still executing the onDataChange() even though the previous value is same as next value.
The main problem is when putting the cursor on the input field but doesn't change any value, it still call onDataChange().
I would like to call onDataChange() only if there is changes in the input value/ changes in the dropdown selection. onDataChange() will invoke the api call, which might takes longer time to retrieve the result.
Does anybody experience similar issue and could provide guidance? Thanks.

QUESTION
I get vertical stripes between the bins when creating a histogram with matplotlib 2.0.2, python2.7, Win7,64bit, visible both in the pdf and png created. I am usig pgf with latex to create a PDF which I will use by includegraphics in a pdflatex document. The PNG created is just a quick check.
This was not the case in Matplotlib 1.5.3. How do I get rid of these white lines separating individual bins?
Things tried:
- Switching antialiasing on/off (aa=True/False in hist command)
- drawing a line (ls="-"/ls="none" in hist command)
- One thing which would kind of work is giving a width to the bins (width=2.3), but this also does not work for a PDF in all zoom values.
