So somehow the data is not linked to the chart - this can happen if you
click on the chart, place the cursor in the Formual Bar and press F9. Right
clcik the chart and select Source Data and open the Series tab to see what
the chart is using for data. if you see somethinh like {1,2,3,} your chart
is disconected from its data.You may need to remake the chart.

Hi Bernard,

It's not new data, it's existing data that I change and it does not get
reflected in the chart. When I click on the line, no line appears around
the
source data cells

Do you mean:
a) when you add data to the worksheet, the new data is not displayed? If
so
read www.stfx.ca/people/bliengme/ExcelTips to learn about dynamic chart;
OR
if sing XL2003 make a 'list' and the chart will be dynamic,
or
b) if you change existing data, the chart is unchanged. When ou clcik on
the
line in the chart, does Excel draw a box around the data in the cells?

come back for more

best wishes
Bernard

when the source data of my chart changes, the chart does not update
accordingly. Is there a refresh button like in pivot tables that I can
press
to update the chart?
