    How to elegantly show multiple significant differences between groups on a bar graph?
    I have measured gene expression across eight time points, and multiple comparisons show many differences between the time points. I'd like to indicate these significant differences on my bar graph. Usually I would draw a line above the relevant bars and put * or ** above the line, but there are so many differences that the lines would become unwieldy and I feel my graph would just look too messy! Any suggestions? Should I just relegate the p values to a table?

    I see. So you can possibly take initials or abbreviations of these interventions, like

    D Significant difference from Dolomitrin-treatment
    M Significant difference from Melomycin-treatment
    Pa Significant difference from Palatosan-treatment
    Pi Significant difference from Parsitin-treatment

    and so on.

    Experience with using visuals to communicate your research.
    If you are willing to publicly share your experiences, I am very interested to hear your thoughts on the use of visual communication for scientific research. Specifically, I am interested in learning:
    - your thoughts on the importance of visuals
    - the type of software you use to create charts, graphs, schematics, illustrations
    - how much time you spend creating these visuals
    - your thoughts on the value of outside expertise to help you create your visuals

    in my opinion visualization is a very important topic.
    When we see some presentations in conferences, symposiums, etc., it is common to see that lots of people don't care with a good presentation, or good ways to display data.
    However, I have an youtube video that shows how to create a 3D animation of a scatterplot. Maybe it can help.

    Please take a look at:

    Any good experiences with Matlab alternatives?
    I am evaluating various Open Source tools for use in EE resarch. Few interesting ones would be Octave, SciLab, Python with Numpy and SciPy. Anyone care to share experiences, good or bad? Any other suggestions?

    Here you can find an interesting report

  • How can I download your visualization ontology?
    I've tried to upload your visualization ontology : in Protégé 3.5, but I encountered a error. Did you check such a import?

    OK. It works fine. Thks !
  • Giovanni Pintore added an answer:
    What's a good visualization tool for a presentation?
    I am searching for a good visualization tool for presenting my research results in a conference. Do you have any fancy tools in mind?

    I suggest Powerpoint too
  • Nancy Rodriguez added an answer:
    Which free software would you recommend for high quality 3D scientific visualisation?
    I use Paraview and have experimented with Mayavi for 3D visualisation (volume rendering, surface plots etc.). I find Paraview can be lacking in quality at times and Mayavi has been difficult to use - are there any alternatives people could recommend?

    VTK is also a widely know software for visualization


  • Roy Trevor Williams added an answer:
    How important is storytelling and visualization for your science?
    Two weeks ago, I attended two interesting presentations, one of a British SME (shoothill) on visualizing scientific data for the public (for example applying a technique known as Deep Zoom), the other of the Polytechnic University of Milan on using NASA world wind as a virtual globe in the area of environmental modeling. Both make me think of the role of visualizing research results depending on the target audience and about telling the right story to the right people. I have the feeling that in my filed (geospatial information science and Digital Earth), we still miss a strong commitment to such ideas and also education has to increase on related topics. Do you share this view / maybe also in other research areas? What are your experiences?

    Hi, visualisation is essential to what we are doing, which is to try to describe the dynamics of learning in open (emergent) systems. We have developed a 3D footprint that tracks 25 variables, simultaneously, across a learning event. It could still do with some automation and interactivity, but its working for us (and for others, too).

    What is the future of scientific illustration?
    Hi there,

    I'd love to hear your thoughts about what you think will be the next generation scientific visualization approach. Will it be interactive? More photo-realistic? What are the skills we need to learn today to keep up in the future?
