Hi SF,
You can extract 200-1000 data points by Worksheet Query and then use Reduce Rows to remove 24 points from every 25 points.
Select Wokrsheet: Worksheet Query, and set it as below:
In the extracted worksheet, select Worksheet: Reduce Rows, and specify settings like this:
You can refer to the following pages for details of Worksheet Query and Reduce Rows:

In order to retrieve data values from a plot follow these steps:
1. Open the figure
2. In the MATLAB Command Window type the following commands:
h = findobj(gca,'Type','line')
x=get(h,'Xdata')
y=get(h,'Ydata')

Thank you for informations.
As I didn't have much time then I simply merged all the worksheets and copied the line with parameters I needed and pasted it with transposing from horizontal to vertical and made graph out of the resulting column.
