Help making a chart that doesn't graph cells without data?
I am setting up a template spreadsheet that will automatically do
calculations and graph groups of data into a single scatter plot chart. I
have a defined set of 13 groups of between 6 & 150 data points each that I
reproducibly collect each day. So I have set up formulae and a chart to
automatically calculate and plot as the data are entered.
The problem that I have is that each day the number of data points in
each group will vary. So I either have too many data points, so some dont
get graphed, or I have too few data points and I get a graph of zeros after
the real data has run out. I figure the first problem is easily solved by
just setting up more rows of formulae then Ill ever need for each group.
But I cant get by the second, if there is a formula in a cell that is within
a charts data range it will graph the value as a zero even if the cell
appears empty.
I am wondering if there is any way to set up, for example, an if
funtion that will return a value that wont be graphed by Excel, or to make
the chart smart enough to not graph data that isnt real? Or is there some
way to set up my functions better?
I am working from the assumption that there is no reason for me to have
to tinker and manually do the same analysis over and over. I am trying to
work smarter not harder. Any help will be appreciated.
