I have set up many dynamic charts using named ranges with the counta
function. At times when reopened the data is not displayed properly - it will
be skewed to the left with blank intervals although all data is there. It
can be corrected by going to the data sheet and resaving the spreadsheet but
this is very inconvenient and doesn't always work. This is particularly a
problem when the spreadsheet is for distribution or to be used as part of a
presentation. Does anyone know if there is a way to 'freeze' the display so
this does not occur?

Thank you!
