        To create this type of plot, the data needs to be converted to x-y coordinates, similar to a polar plot.

        The conversion to x-y coordinates is as follows:
        x = r * cos(θ)
        y = r * sin(θ)
        where
        θ = angle in radians
        r = radius from the center

        We updated our older template and added two new templates that you can find now in the example files.  The Basic Spider file has all the equations set up along with two sliders to adjust the plot.  This would be a good place to start to see how the plot is constructed. The Spider plot template has more sliders to give you more options for adjusting the plot along with more data.

        Please let us know if these files are helpful or you need something different.

          I would also find these very useful. My scales generally run from 0 – 100 (rather than 1 to 5, or 1 – 7); is it relatively easy to adapt these plots accordingly? I’ve had a few goes bit without success! Thank you.

            In the Spider Plot Template file (second in the list), you can adjust the levels (number of rings) and the step size between them.

             

            Sliders

            Here is the grid with the above settings …

            Here is the grid with Levels = 5 and Step = 20.

            Grid2

            Does this help?

            FYI – Click the note to the right of each of the sliders for a short description of what each does. If there is something else missing, we can create other adjustments in the template.  Just let us know!

              Ahhh, that’s how it’s done!! Brilliant; I’ve now made exactly what I needed. Thanks so much for your help 🙂
