How to force y Axis to use floating point precision?

I used this code from kandy examples:
```
val years = listOf(1, 2, 3, 4, 5)
val cost = listOf(62.7, 39.3, 72.1, 73.7, 68.5)

plot {
line {
x(years)
y(cost)
type = LineType.SOLID
}
}
```
And when you hover over the resultant plot values, we see y axis labels that correctly show values with decimal point like 62.7, 72.1 etc.


But if I use this dataset instead:
```
val years2 = listOf(1, 2, 3, 4, 5)
val cost2 = listOf(95.0, 2.2, 3.3, 4.4, 5.5)

plot {
line {
x(years2)
y(cost2)
type = LineType.SOLID
}
}
```

I get a plot where all y values are rounded off to the nearest integer. I don't understand what is causing this and how to force y axis to be of Double type.


How do I force y axis to use decimal values?

Reproduce the two Kotlin plotting snippets from the issue and compare the y-axis label behavior when the values span a wide range. Trace the y-axis scale and label-formatting entry points to determine why decimal values are rounded, then verify that the affected plot displays decimal labels without changing the first example.
