VizPainter: Tableau Tips and Tricks, Storytelling, and Data Visualization

Welcome!

I started blogging here in May 2014 to share Tableau tips and tricks.  Things have really taken off since then!  I continue to share tips and tricks and I still focus heavily on Tableau – the tool that allows me to have a seamless conversation with data, draw insight, ask questions, and get answers that sometimes initiate action and sometimes deeper questions.

Along the way I’ll also share some broader dataviz lessons and maybe a story or two – possibly some data storytelling and even some stories of my journey in the world of data and data visualization.

Best Regards,
Joshua Milligan

    Hello Joshua,

    I was at the User Group where you did the demo Games in Tableau at Teknion. Towards the end, you show a dashboard of Rep sales, I believe, with links to another dashboard. I remember you mentioning that you will have that on your website, but I cannot find it. Can I download it? If so, would you be able to send me a link to that dashboard?

    Thanks,
    Kary Tran

    Hi All,

    My question is around, how can we set/change the default shape directory.

    I am currently working on to set an org structure for a company. The scenario is that people keep joining the company and I want Tableau to pick a default image in the org structure instead of default available shapes (circle, square, plus, etc).

    You can see the snapshot of the dashboard, where I do not have the image for resource3 and Tableau picked + automatically. P.S.: the above snapshot is sanitized and I used gender icons for the image instead.

    Please help me figure out either, how to add an image as default in the default folder and location of the default folder? or how can I set a different folder as default?

    Hello Joshua,

    I have been following your posts and YouTube videos and I have learned a lot from them. I have also searched the web and not found a way to show conflicting dates in a Gantt Chart.

    For instance, I am trying to visualize a set of projects in a Gantt chart and highlight conflicting dates. Below is a link to a similar question that was asked on the Tableau website:

    https://community.tableau.com/thread/156106

    If there any way to achieve this using Tableau 9?

    I would appreciate any assistance. Thanks for the good work you do.

    I ran across the photo of the men with the Unions Make Us Strong sign on Facebook. The man in the white fedora looks exactly like my father. Do you have any knowledge of when and where this photo was taken or where I could find additional information about it? Thank you.

    • Joshua Milligan says:

      Jeanne,

      That’s fascinating! The image itself came from a Google search and I remember reversing it (you can see the sign in the background says “Paint” but is a mirror image) and I replaced the text in the sign the man was holding. I don’t recall what the original text said. I’ve tried finding the original image by searching terms I might have used and also searching by image (the way it is and reversed back to the way it would have been) but cannot locate it right off. I also don’t seem to have the original image anywhere. If I do find anything or suddenly recall what I might have searched I’ll let you know!
