I need to be able to plot (for example) the following values on a chart:

4.5
3.1
5.3
2.1
<1.0
2.5

The value <1.0 is there as we cannot give the exact value if it is less than 1 but we need to display it.

Is there a way of just displaying the datapoint label with '<1.0' as text, or something similar?

Thanks!
