how to use xmgrace to plot histogram from a plot -


I have a text file with two columns (say, sample1.dat): first column 1 to 5000 and second Columns are 5000 degrees angle, in which degrees range from -180 to 180 degrees. Using the "Xmgrace sample1.dat" command, give me a bizarre diagram vs. serial no met.

To get the histogram from the plot, I did the following in Grace's pop-up window: Data -> Trasnformation - & gt; Histogram

In a new pop-up window called 'Grace: Histogram', I selected the source graph, but did not make any selection in the destination graph as mentioned in any maintenance tutorial. After starting in -180, close as 180 and close the number of bins as 5 and then in the window, by killing the 'Accept' command, I got the following error message: < P> [Error] Please select a source and destination article

Help me get the histogram from plot. I want to use xmgrace to plot a histogram. I know how to plot it using some of the most widely used plotting tools like gnuplot and others.

You almost did it! Here's a complete step-by-step solution: Save the data in the two-column file "sample.dat" Here's the content of such a file: 

  #in angle 1 132-162 3 -63 4 53 5 -170 6 80 7 173 8 39 9 113 [etc ...]   
 In my example file I have 40 entries, with randomly generated angles Call the xmgrace from the command line and load the data file:  
  xmgrace sample.dat   
 Firstly you plot a line of angle vs n will see. We can batch the data and tell the histogram as follows:  
  Data & gt; Transformation & gt; Histogram   
 This will open a new window called "Grace: Histogram". Right-click on your data set "G0.S0" and duplicate it. Select the original data set once left click on the left hand panel. Select the new data set "G0.S1" on the right hand panel.  
 Now select your binning parameter at the bottom of the window.  
  Get Started: Close -180: 180 # Boxes: 5. Click   
 Click  Apply . The histogram is now plotted but the original line plot is required to be hidden. Right-click the original data set "G0.S0" in the left hand panel and select "hide".  
 After all these steps the "histogram" window should now look like this:  
  Grace histogram window   
 Finally, in the main XMgras window, resize the plot. Now you should see the histogram, in which your angles are tied in five compartments. Angle ranges are shown on the frequency of each bin at X axis and y axis. Here is a default output where I have labeled axes:

 The number of frequencies coming from all the bins should be added to the number of data lines in the sample.
