Chart question
 

Hello
I have a data collecting system that automatically goes and polls 4 seperate
systems and populates 1 worksheet for each system. Certain systems will not
always produce data, leaving gaps in the data viewed from a date
prospective. I have 1 chart with 4 series. Before I plot this data, I scan
the 4 worksheets and set the category (X) of my chart to reflect the series
that has the most days of data in it. All data will be displayed in my chart
but will not be charted against the date that it occurred except for the
series I choose to be category (X).

Example:

System 1

Jan 1,data1

Jan 3,data2



System 2

Jan 1,data1

Jan 2,data2

Jan 3,data3



I would use System 2 for the category (X) and system 2 data would be
plotted correctly relative to the date. System 1 will be plotted so data1
and data2 occurred on Jan1 and Jan2. What I need is data1 plotted against
Jan1 and Jan2 be blank and data3 against Jan3. System 2 would have data for
Jan 1, 2 and 3.

I know this is because of how I set my category (X).

Is there a way to tell excel there are 4 category (X) series to this 1 chart
but only display the one that is most dense to cover all data?



Thanks in advance,

Cheers!
