I'm using an XYChart to plot a Dataset tag in Ignition Perspective. The Y axis labels are only showing 2 decimal places and a trailing zero. Any idea how to fix this?

To describe what's happening a little more clearly, the y axis tick labels are being rounded to the nearest 0.01.

What is the formatting under `properties.yAxes.value` set to? You may need to add an additional point of precision.

Hmmm, there's something not right there.  
If I drop in the default XY Chart component, delete the second yAxis and series and change set `yAxes.0.value.format : #,###.000 mm` I get '20mm', etc., without the space.  
Making it `#,###.000 %` results in '2,000.000%'.

See if the AM Charts (on which the component is based) documentation has any clues. See the bottom of [Value Axis – amCharts 4 Documentation](https://www.amcharts.com/docs/v4/concepts/axes/value-axis/#Formatting_labels) and the bit that says,

> This is why `ValueAxis` will try to automatically format all numbers using the same number of decimals as the most granular label currently displayed, e.g.: `1.0` , `1.5` , `2.0` .

There's a dropdown beside `yAxes.0.value.format :`. Choosing the 'a' for 'abbreviation' suffix fixes the problem for numbers in the range 0 to 100.
