legend for scatterplot

saidurgamalleswarthota — Mon, 25 Oct 2021 05:35:44 GMT

Hello,

I'm trying to use three variables at a time in a scatterplot. I chose two variables for the x and y-axis. And the third one is the size of the symbol proportional to the attribute.

Can anyone please tell me how to make a legend for the plot showing the details of axis and the size of the symbol? I'll attach the figures for reference. Thank you.

I want to show the radius of symbol ranges in the legend. Please help.

Hello saidurgamalleswarthota,

I am assuming you are trying to do this within the Scatterplot Chart in Map View using ArcGIS Pro. I do not think there is the capability to make a legend within that chart. However, I did think of a workaround for you that involves creating a layout view. Please see below:

Step 1: In map view, create scatterplot and define settings.

In the Contents window, define Symbology to match the desired proportional symbology (see purple box, MapView.png).
If the Show linear trend "legend" item is not desired, turn it off (see red box, MapView.png).
This is done in Map View (see green box, MapView.png)

Step 2: Create a New Layout --> Insert Map Frame w/ data, Chart Frame, and Legend using Insert Ribbon

In Drawing Order window, only Legend and Chart Frame need to be toggled on (see purple box, LayoutView.png).
In the layout, arrange elements as desired (For illustration purposes, see blue border {Chart Frame} and purple border {Legend}, LayoutView.png).
This is done in LayoutView (see green box, LayoutView.png).

Once edited to your satisfaction, it can be printed, exported as a PDF, exported as a png --> whatever is needed for your purpose. I hope this is helpful.

Cheers!

Hi, I would not use a bubbles as a third variable (actually scatter plots are used to show trends/possible correlations between 2 variables) since it is confusing for reader. The line is good for central tendency (you should label this). I would suggest an heat area visual around the dispersion (darker colors near the line, lighter shade moving away from the line) and a side visual for proportions.
