Autoselect data using Macros
 

Hi,
Here is what I am trying to achieve in Excel.

Have sheet where the user will enter data. The range of data can be
variable each time. between 4-8 rows and two columns (A and B).

I want to write a macro that will do the following:

1. Find the first blank row in column A and now it has the range of
valid data.
2. Use the range from Step 1 to create an XY chart where data in Col A
is X Axis and Col B is y-axis.
3. Label the chart and place it on the same sheet as data.

Please let me know how to handle dynamic/variable range selection in
Excel Macros.

Thanks,
Shoaib

set rng = Range(Cells(1,1),Cells(1,1).End(xldown))

or if there will be blank rows in the data

set rng = Range(Cells(1,1),Cells(rows.count,1).End(xlup))

now you can use rng to build your chart.

not
set rng = rng.resize(,2) will expand the range to include two columns
set rng2 = rng.offset(0,1) will set a separate reference to column B.

Turn on the macro recorder and build the chart manually.

then modify the code recorded to use the code above.

Shoaib: Here is how to find the last row of data in a column and set that as
a range:
Dim Lrow As Long
Dim rng as Range

Lrow = Cells(Rows.Count, "A").End(xlUp).Row '"A" can be any column
Set Rng = Range("A2:A" & Lrow) 'starts at row 2 to allow for header

From here you can merge a recorded macro of creating your chart.

Tom,
Thanks for the response. I thought I would be able to handle this on my
own but I guess I am a real novice at VBA.

One thing that I forgot to mention was that after finding the range of
data I would also like to sort the data based on Column A and then hand
it over to the chart. Any suggestions there?

Thanks,
Shoaib

Ok so I figured out the sorting part. Here is what I have now

Set rng = Range(Cells(1, 1), Cells(1, 1).End(xlDown))
Set rng = rng.Resize(, 2)
Set rng2 = rng.Offset(0, 1)
rng.Select
Selection.Sort Key1:=Range("A2"), Order1:=xlAscending,
Header:=xlGuess, _
OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom
Charts.Add
ActiveChart.ChartType = xlXYScatterSmooth
ActiveChart.SetSourceData Source:=Sheets("Sterngth Duration
Curve").Range _
"A2:B9"), PlotBy:=xlColumns


Where the last line for selecting data source was created by the Macro
recording tool. How do I modify that line to take the range from rng
variable insted of a fixed range every time the macro is run.

Also is there a way to look for a chart on a sheet, delete that chart
and then create a new one using the above code.

Thanks
