You plan to create a visualization that has a dual axis chart. The dual axis chart will contain a shape chart and a line chart. Both charts will use the same measure named Population on the axis.
You need to configure the shapes to be much larger than the line.
What should you do?
To create a dual axis chart with independently configured shapes and lines, you should duplicate the measure Population and drag it to the second Marks card. This allows you to configure the size of the marks (shapes) independently from the line chart. By duplicating the measure, you can ensure that the shapes can be made larger without affecting the line chart, which is essential for the visualization you intend to create.
Easiest way to selecting second axix(shape) -> go to size -> adjust the size as per need. This option is not there will go for custom size in given option.
For me A, because given that we need to have a dual axis with the shape being larger, we need to configure or customize the two different axis different and independent of each other.
