Data selection on line chart

[Qiset]

I'm collecting data but only want to chart the last 60 points on my line chart.
To do this I have to manually update the series value information in the source data.
for example: I have 176 rows of data and the chart series
value is "=sheet1$b$117:$b$176" if I add a new row I have to
change this to "=sheet1$b$118:$b$177".
Is there any way to use a variable for this? say LRD is the last row of data
could I change this value statement to be "=sheet1$b$(LRD-59):$b$(LRD)
so that anytime I add a new row it would update the chart?

thanks,

Hi,

You need to use dynamic named ranges. See Jon's explanation which you
can modify to plot the last 60 instead of last 12 periods.
