I have a chart YX_CHART log-log with this parameters:
B4X:
chtCurvas.YScaleMinValue = 0.008
chtCurvas.YScaleMaxValue = 4000
(I have this same code en B4A and I don't have any problem)

But I doesn't see the lines y-axis (see image), if I change:
B4X:
chtCurvas.YScaleMaxValue = 900
I can see the lines (see image) but If I change again chtCurvas.YScaleMaxValue = 901, appears this error

B4X:
Error occurred on line: 4018 (xChart)

Any idea to put YScaleMaxValue = 4000 and see all lines (y-axis)?
