Hi,
I generated a sample of lognormal distribution using Simbiology analyzer. I want to extract the data of the samples' histogram to plot the exact histogram using graphPad prism. Could you please tell me how to extract the data of the histogram plot to generate he same graph in prism?
Thanks

What is "graphPad prism"? Is that a third party plug-in for MATLAB, a product of Mathworks, or some separate program?

Thank you. I want to plot to generate the same attached histogram in another program

You can export the samples you generated using Model Analyzer to an Excel file:
  • Find the samples under your program results
  • Drag and drop "samples" to a Datasheet
  • Right click on the Dataseet and select "Export Datasheet"
Please see the screenshot below:

Hi Fulden,
How can I exctract the characteristics of the attached histogram so that I can generate the same figure in another program?
Hi, can you be more specific about what characteristics you're looking to extract?

First, what does the vertical axis represent in the attached figure (Q3)?
How can we know the bin size?

Since this is a histogram, vertical axis represents the number elements in the bin. You can get information such as bin width, number of bins, bin edges, etc. by checking histogram's properties.
For a histogram created in Model Analyzer, first right click on the histogram and select export plot. This will export as a MATLAB figure. You can then get a handle of the histogram by typing the following in MATLAB Command Window:
fig = gcf;
hist = findobj(fig, 'Type', 'Histogram');
Once you get a handle to histogram, get some of its properties as KSSV showed above:
% get bin width
binWidth = hist.BinWidth
% get bin edges
binEdges = hist.BinEdges
% get number of bins
binEdges = hist.NumBins
