How to "lock" a chart reference

Question

I use numbers to track daily activities for my business. Each row is a day and the columns each represent the different activities I track.
I use a pie chart to visualize how my work day is split up between these tasks.
Creating a year-to-date pie-chart was simple... Creating a chart from a footer row totalling each column.
HERE'S MY QUANDRY:
I like seeing a "today" chart as well... Since as each day passes I add a new row to the top of the sheet - I initially tried creating my chart from that first row. However - the following day when I add a new day (row) above the previous day - the pie chart reference stays with the original row I defined it as. I must be missing something... somewhere... (?) - I'd like to tell my pie chart to ALWAYS and ONLY reference the second row of the table. (b2).
I thought I'd be clever by adding another table with a single header (matching my primary logging table) and a single row and in each cell of that row referencing it's counterpart in the main table. Again - the references shift as soon as I add another row.
ARRRGgh!!  I mean - yes... I can (and have) simply been redefining the chart references daily as a workaround. Pretty painless on the desktop version. Though on the iOS version - this is a pain. It would be wonderful if there's a way to simply tell that one pie chart to ONLY look at Row 2 for data.
Here's a screen shot:
Hopefully this is something just so incredibly easy I'm overlooking it.
Someone - please make me feel dumb!  :-)

Try something like this...
I made two tables similar to yours.  The top one is name "Entry" then bottom one is named "Today"
In the table "Today" enter the following:
A1=OFFSET(INDIRECT("Entry::A1"), 0, COLUMN()−1)
this is shorthand for... select cell A1, then type (or copy and paste from here) the formula:
=OFFSET(INDIRECT("Entry::A1"), 0, COLUMN()−1)
select cell A1, copy
select all the cells in row 1, paste
