问题
I'm using Multiple Y axis Graph for plotting points
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 Same 5 series of lines(Weight) on Y2 axes both with respect to x-axis,,,,No problem exists here,,,these series of lines are standard lines and used for every calculation,,
b)Now If user enters both his height and weight I draw two extra Lines ,so there are 12 series of lines including standard lines,,
c)Supppose if the user enters alone Height but not weight the app force closes,,saying dataset and renderer should not be null and should have same number of series
code follows,,
public GraphicalView execution(Context context, String UserName,

回答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..
