I find BaseX a very powerful tool.

One thing I noticed however is that it misunderstands numbers in scientific notation in the scatter plot display.

Please see the attached plot.

The samples should form a rough diagonal line.

However, look at the scale on the left and you can see the exponent field is 'dis-continuous'.

It looks like the chart formatter treats it as a non-scientific number or possibly even lexicographic order.

Best Regards
