I am new to this forum and not familiar with drawing a diagram. The concept is very simple so I'll try to describe it.
Lets use a simple 3 bar 10 min chart. Each new bar will be exactly 10 minutes.
Now let's use a software variable bar chart. Bar  is 10 min; change bar to 15 min; finally change bar to 8 min. Each bar length is changed at the opening of that bar. The changes are variable and are from the software in realtime.
Use underlying tick data.
you can use 3 data streams... 10 min, 15 min and 8 min.
just make the chart display the resolution you want at the time you want,
and make the rest invisible.
