- 7. about journey theviz skills tutorial follow Duplicate your dataBring in your sheet 4 times into the data source pane. Tableau will create a field called ”Table Name”. Path Order FieldUsing Table Name, we will create a calc to identify each of the four points – one data set per point. Parameter FieldsUsing polygons means we can have a lot of flexibility over our viz. Create 3 parameters to allow for adjustments. Building the VizX to rows, Y to columns, dimension to detail, mark to polygon, table name on path, change X/Y compute using the dimension. Customizin gAdjust the inner and outer radius and the spacing between the “tabs” by using the 3 parameters. Coordinate CalcsSeven calcs are needed here to build the radial points: index, angle, degrees, radians, radius, X and Y.
