Four ways to change opacity of scatter markers | scatter chart made by Alex | plotly

Alex's interactive graph and data of "Four ways to change opacity of scatter markers" is a scatter chart, showing trace 0, trace 1, trace 2, trace 3, trace 4, trace 5, trace 6, trace 7, trace 8, trace 9. The x-axis shows values from -1 to 1. The y-axis shows values from -0.6705426356589166 to 3.670542635658917. This visualization has the following annotations: Fully opaque. When there are many points they overlapand you don't get a good feel for their density; {opacity: 0.5} - lets you see traces behind this one, butdoes not let you see point density any better thanthe opaque trace; {marker:{opacity:0.5}} - lets you see density of points,but in places with a very high density you cannot seetraces behind this one. Sometimes a good strategyis to combine this with trace opacity.; {marker:{color:'rgba(....,0.5)'}} - similar to marker.opacitybut since the line is opaque this emphasizeseach point more; {marker:{line:{color:'rgba(....,0.5)'}}} - a weird effect.Almost never a good idea unless thereis no fill, when it's equivalent to marker.opacity
