Question
How do I add units, such as % to the labels on my chart's x axis?
Answer
In order to have (%) displayed for every numerical value on the axis, the axis 'Label Style' element needs to be added which comes with format attribute that can be adjusted as shown below.
This Document lists valid formats for the label style element
In this case, the format attribute needs be set to “##\%” to set the labels to have percent signs appended to the numbers.
