Charting Multiple Data Series Using ONE Selection?

I would like to create a chart with 2 or more data series selections. These series' would be identical but offset by a specific distance along the horizontal axis. I currently create multiple columns to derive each selection from. The data is simply shifted by a given number of rows to create the offset with regard to time. This is the most accurate way I know of to maintain the correct separation of each series but is time consuming to update the chart.
It seems there must be a way to make just one selection of the data for a given chart > create multiple instances of the selection > offset each instance as required for proper time separation along the H axis.
I use the term 'offset' but I do not know if it would be used here.
I can attach a sheet if Im not being clear enough here. Im just assuming its a rather simple task.
Thank you.

Thanks for your interest Palmetto.

The file I have attached: Data in Col. B is replicated in C & D, but occupying a later date respectively. I selected BCD as a group to create the chart, which formats as desired. I would like to avoid the existence of Cols. C and D altogether, yet still create the same 3 series chart. Can I format a chart this way(ie. 3 series' separated by 10 days) but only make one data selection from Col. B?

My goal is to easily update this chart without selecting each series individually and enlarging the selection to include new data.
