Dear all,
How can I draw the cumulative probability of 75 samples in 1 chart? For example of 1 sample:
2000 (micron): 4.7%
1000: 8.6%
500: 53.7 %
250: 99%
125: 99.8%
63: 100%
Someone can help me with that? Thank you very much.

Hi,

It seems that your data has been already cumulative, so essentially you can simply make a plot from the data in every worksheet. Also, the X data is already sorted to be plotted in order.
Please try the following script. (You need to remove % from the Y column to be treated as numbers.)
//////////////////////////////////////////////////
%K=Graph2; //existing graph window name
doc -e LW {
  set col(1) -dc 1; //set 1st column for X as categorical;
  worksheet -a 1;   //add one column;
  plotxy (1,2) plot:=202 ogl:=[%K]1;
  //203=Column 202=Line+Symbol 201=Scatter 200=Line 
} 
layer -g; //to group plots 
//////////////////////////////////////////////////
In addition, Note that if you need to create individual graphs instead of adding plot into a single graph, you can use the Origin's Batch Plotting feature.
