I have 1)X-axis 2)Y1-axis 3)Y2-axis

a)Initially I used to draw 5 series of lines on Y1 axes(Height) and Sam

Answer 1

sorry the problem was with the logic i have used above ,I have changed the line

if (!(mWeightInKgMonthDate.isEmpty() && mHeightInCmsMonthDate.isEmpty()))

to

if (!mWeightInKgMonthDate.isEmpty() && !mHeightInCmsMonthDate.isEmpty())

thats it..
