So you are using a variable width display, making things in coincidence, but it is an artefact useless in backtesting.
It's a display trick like the backplot features.

I'm not creative , I am logical.
I'll demonstrate:
these two series have the same time stamp for the first and last tick of both series for sake of simplicity
0] 1 2 3 4 5 6 7 8 9 10] data1
0] 1 2 3 4 5 6] data2
Now, explain us how you make two 5 ticks bar with these two series
and make them coincide where they should...ie at tick 5 of data1 !!!!!!!!!!!!!!!!!!!!

This is what you do.
I have has a closer look to your examples with a larger scale.
It is obvious that the horizontal scale may vary.
But it's an approximation, and you will NEVER find a tick serie where REGULAR spaced ticks may coincide at every end of the tick bars of ALL the series.
