Can you show us a sample of the data - for example are the Point ID's
numbers, dates, text?

What version of Excel are you using?

What kind of chart are you using - line, scatter, column....?

Notes: Excel supports substantially more data points than you are trying to
display.

Here are the limits for 2003:

Feature Maximum limit
Charts linked to a worksheet Limited by available memory
Worksheets referred to by a chart 255
Data series (data series: Related data points that are plotted in a chart.
Each data series in a chart has a unique color or pattern and is represented
in the chart legend. You can plot one or more data series in a chart. Pie
charts have only one data series.) in one chart 255
Data points (data points: Individual values that are plotted in a chart.
Related data points make up a data series. Data points are represented by
bars, columns, lines, slices, dots, and other shapes. These shapes are called
data markers.) in a data series for 2-D charts 32,000
Data points in a data series for 3-D charts 4,000
Data points for all data series in one chart 256,000
Line styles 8
Line weights 4
Area patterns (screen display) 18
Total area pattern and color combinations (color display) 56,448
Pattern and color combinations (color printer) 56,448 (the actual number
depends on your printer and its software)

Column A = Point ID
Column B = Northing
Column C = Easting

My datasheet has about 200 entries in it.

My chart shows all these entries, but the last 10 or so points on the chart
no longer have the Point ID beside them. All my ranges appear to valid.

Any ideas?
