      Hi,

      How to draw the Nightingale rose diagram with DataGraph? Does it work, I know someone can draw it with Excel, Python, R and Origin. Thanks!

        Yes – you can absolutely make graphs like this (with no coding needed!).

        We grabbed the ‘Nightingale’ R dataset to demonstrate.

        Here is a graph we created….

        Florence Nightingale

        You can download the file that creates these in DataGraph (Go to File\Online Examples…).

        Here is the basic approach …

        First, we created a base layer.

        LayerOneImage

        This is created with a single Pie command.

        (For a quick demo: How to make a Pie Chart )

        The Values in the column ‘Wedge’ are simply all ‘1’ so the wedges will be uniform.  There was some adjustment to get the wedges in the right location (compared to the original graph we were recreating) and the month label was added.

        LayerOne

         

        The first Pie command can be copied (command-C) and pasted (command-V) to create additional data layers with the same settings.

        Here is the first data layer added (one more Pie command):

        LayerTwoOut

        The main addition here is the use of the Width option.

        LayerTwo

        The column ‘C’ is from the data we want to represent, but note that these values have been scaled so the area of the wedge corresponds to the data.

        Please see the file for the full details.

        If you are interested in making a graph like the screen shot you sent, you would use a color scheme to color the slices and you only need one Pie command.

        If you have a data set in mind, feel free to forward to us.

        Does this help?

          FYI – we posted an example file that creates a graphic similar to the screenshots you posted.

          Spectrum

          This also has multiple commands that are layers to create the various design elements, but only one command is needed to draw the colored wedges.

          The command uses a color scheme for the fill …

          Spectrum2

          This file is also available in File/Online Examples.

          The one design feature we don’t have yet is to have text labels with rotating text, where the angle can change for each entry.  This is something we plan to add in a future version.
