For what are you going to use the program?
  • i need to do the good fittings of my graph for research purpose and to make it easier to do changes in the graphs if required like adding axis

  • for using graphics in biology projects and other utilities in studies attached to the sciences, to improve the quality of jobs and represent a mathematical model investigations made

  • studying purpose. I do not use for analysis works. Please send me the software for free. I am a student and I cannot afford a large amount of money.

  • We developed a micropropagation protocol for Paeonia. Surface sterilized explants with one node were placed on a medium based on Lepoivre in.

  • I each research methods and graphing techniques. I am going to use it for plotting graphs and for teaching of postgraduate students at the sch

What similar programs have you used?
  • i have been using the progrmm microsoft excel sofar. now i need something bette and i came up with sigma plot. so ich just want to test it and check if it works properly.

  • I have used origin pro and I like it but it is too expensive. SPSS cannot do the same job either. Excel works, but not quick enough. Isdflkjgsdf

What do you like most about this program?
  • Sigma Plot is the standard bearer for scientifc graphic programs. It beats Graphpad Prism hands down. I do wish that it would function with Windows 10

  • drwing sheets and graphs to iluminstarate the difference between my samples of nanoparticles also to identify the absorbance beaks of IR and XRD

  • draw my main conclusions & create exact graphics with a very useful graphic visualization mode in order to increase its efficiency and usability.

  • whenever I want to use a serious softawre I have got to keep in mind that a good software is not enough I need an Excelenet one so no worries

  • The various possibilities for plots and statistical analysis which are very important in professional use, given that I am using it in scientific purposes


SigmaPlot - An excellent graphing software perfect for engineers, statisticians and mathematicians

Working with an engineering and environmental firm, I have always enjoyed working out in the field, recording raw data results and measuring other technical data. However, when I’m back in the office and processing all this information, I find it to be a bit of a daunting task, in more ways than one. I also have to translate all this technical data into visual format such as graphs and spreadsheets so that they can be available in visual presentation form. At last I found a software application that can make my work easier and faster. That software is SigmaPlot.

I downloaded the free version of this software and found that I perform a wide range of analytical and mathematical functions with this application. I could create graphs, selecting from over a hundred 2-D and 3-D types of graphs. Customizing details of my graphs and even charts was fluid and easy. This will really make my superiors glad since I could make my visual presentations easier to understand. I was also happy to discover that I could use SigmaPlot with Microsoft Excel, where the bulk of my field data resides. Access to Regression Wizard allowed me to process recorded data very conveniently and precisely. I also used Global Curve Fitting and Dynamic Curve Fitter in analyzing multiple technical data.

All this functions and a broad spectrum of other functions make SigmaPlot perfect for scientists, statisticians, mathematicians and engineers like me. I highly recommend this awesome software.


  • Gives you the ability to translate data into accurate graphs
  • An amazing graphing application allows you to make graphs for virtually any discipline
  • Customize the details of your graphs and charts easily and quickly
  • Select from over 100 graph types that suits your need


  • Software may present a bit of a steep learning curve for novice users
Ease to access guides and manuals:
