Hi Sam,

For the x-coordinates, just use an empty array with zero elements or a value that indicates there is no parameter. The exact code depends on your programming language. It can be "null" or "DoubleArray(0, 0)" or "nil" or "Nothing", etc., depending on the programming langauge. The x-axis can be configured with labels using Axis.setLabels.

An example in C#/Java is:

ScatterLayer layer = c.addScatterLayer(null, dataY, ......);
c.xAxis().setLabels(anArrayOfTextStrings);

If there is no x-coordinates for the scatter layer, ChartDirector will just put one symbol at each label position.

For the y-coordinate, you can treat the "%" as a unit, just like "km", "kg" are units. There is no need to include the unit in the data array. For example, for 116%, just use 116 as the data value. On the y-axis, you can configure the formatting as follows:

//The following is in C#/Java
c.yAxis().setLabelFormat("{value}%");

It means to display the axis label, followed by a "%" character.

Hope this can help.
