[jCharts-users] Y-axis value range

[G <sys...@ya...>]

Hi!

Thanks for a great package! Truly professional work!

I'm trying to create a normal LineChart with Y-axis
values ranging
from the lowest data value to the highest data value.
How do I do that? (Zero is always the lowest Y-axis
value)

I've tried something like:

axischart[i].getYAxis().getScaleCalculator().setMinValue(mindata[i]);


but every time I call axischart[i].render() it sets
the min value to zero again.

And the axischart[i].getYAxis() seems to return null
before I call axischart[i].render(), so the first
rendering will alway be wrong, or am I missing
something?

Thanks for any help!

I get a null pointer on that too.

you need to create a new ScaleCalculator and set it to the Axis

Why isn't that in the DualAxisComboTestDriver ?
