android - Achartengine Line Graph -
i'm using achartengine create line graph. current month showing second line, last month, isn't showing it. here's lass , logcat: can see logcat dates correct , count previous month. why not showing beyond me.
log cat:

<color name ="base">#51bbc2</color> <color name ="complementary">#c25951</color> 
thanks @dan lead me solution. went , logged points make sure right values getting placed in right array , come find out yarray.add(c.getint(c.getcolumnindex(statusdata.key_charting_temperature))); somehow got deleted. works! yay!
