In Spotfire client, if customer choose "Dual Scales" he will be able to adjust the parameters and format displayed on two axes.
Following the below steps:
1- Go to any plot (e.g. Bar plot)
2- Properties > Y-axis > Dual scales
Then you can change between left and right scales.
But, in webplayer this is not possible, as there is nothing related in visualization properties.
We'd like to have the ability to do that using web player.
See attached picture.
