Can we change the shape of the Bubble in Bubble Chart.

SASuserlot — Wed, 21 Jun 2023 20:25:55 GMT

Please tell me if it's a stupid question. I am looking to create a bubble graph. But I want to change the shape of the bubble. Is that possible? (this may be a stupid question sorry!); if it's not possible, is there any other alternative way. Thanks

Instead of using a BUBBLEPLOT, use a SCATTERPLOT with the SIZERESPONSE option to have the marker size vary by data value. the SIZEMIN and SIZEMAX options can be used to change the min and max size range of the markers. Then, just use MARKERATTRS=(symbol=<some symbol>) to set the shape you want.

Hope this helps!
