android - mpandroid chart certain methods unable to resolve -

so i'm using awesome mpandroid chart library make simple linechart. able customize heavily using example project on github.

the problem is, when move own code, methods no longer able resolved:

mlinechart.setextraoffsets() , mlinechart.setautoscaleminmaxenabled() in particular. there might others these 2 i've noticed.

everything else works fine though. idea why can't access these 2 methods? should dig find out more why case?

public class myfragment extends fragment { private linechart mlinechart;  // stuff here  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {      // stuff here      // creating numbers line chart candidate     linechart numchart = (linechart)view.findviewbyid(r.id.numberslinechart);     setnumchart(numchart, mobject.getnums());      // stuff here     }  public void setnumchart(linechart linechart, list<integer> nums){      mlinechart = linechart;     mlinechart.setdrawgridbackground(false);      // no description text     mlinechart.setdescription("");     mlinechart.setnodatatextdescription("you need provide data chart.");      // enable value highlighting     mlinechart.sethighlightenabled(true);      // enable touch gestures     mlinechart.settouchenabled(true);      // enable scaling , dragging     mlinechart.setdragenabled(false);     mlinechart.setscaleenabled(false);      // if disabled, scaling can done on x- , y-axis separately     mlinechart.setpinchzoom(false);      // create custom markerview (extend markerview , specify layout use it)     mymarkerviewv2 mv = new mymarkerviewv2(getactivity(), r.layout.custom_marker_view, mlinechart);      // set marker chart     mlinechart.setmarkerview(mv);      // disable axes lines , labels     yaxis leftaxis = mlinechart.getaxisleft();     leftaxis.setenabled(false);      mlinechart.getaxisright().setenabled(false);      xaxis bottomaxis = mlinechart.getxaxis();     bottomaxis.setenabled(false);      // add data     setlinechartdata(nums);      //this method cannot resolved********************     mlinechart.setextraoffsets(30f,50f,30f,0f);      // legend (only possible after setting data)     legend l = mlinechart.getlegend();     l.setenabled(false);      mlinechart.invalidate();  }  public void setlinechartdata(list<integer> nums){      //create xvariables aka strings of months     arraylist<string> xvals = new arraylist<string>();     (int = 0; < nums.size(); i++) {         xvals.add(month.getmonthfromindex(i).getabbrev());     }      //add corresponding numbers     arraylist<entry> yvals = new arraylist<entry>();     (int = 0; < nums.size(); i++) {         yvals.add(new entry(nums.get(i), i));     }      // create dataset , give type     linedataset set1 = new linedataset(yvals, "dataset");      set1.setcolor(color.black);     set1.setcirclecolor(color.black);     set1.setlinewidth(0.75f);     set1.setdrawcircles(true);     set1.setdrawvalues(false);     set1.setcirclesize(1.75f);     set1.setdrawcirclehole(false);      arraylist<linedataset> datasets = new arraylist<linedataset>();     datasets.add(set1); // add datasets      // create data object datasets     linedata data = new linedata(xvals, datasets);      // set data     mlinechart.setdata(data); }  // stuff here  class mymarkerviewv2 extends markerview {      private textview markercontent;     private linechart mchart;      public mymarkerviewv2(context context, int layoutresource, linechart lchart) {         super(context, layoutresource);          mchart = lchart;         markercontent = (textview) findviewbyid(r.id.markercontent);     }      // callbacks everytime markerview redrawn, can used update     // content (user-interface)     @override     public void refreshcontent(entry e, int datasetindex) {          if (e instanceof candleentry) {             candleentry ce = (candleentry) e;              list<string> months = mchart.getlinedata().getxvals();             markercontent.settext(months.get(e.getxindex() % 12) + "\n" + utils.formatnumber(ce.gethigh(), 0, true) + "%");         } else {             list<string> months = mchart.getlinedata().getxvals();             markercontent.settext(months.get(e.getxindex() % 12) + "\n" + utils.formatnumber(e.getval(), 0, true) + "%");         }     }      @override     public int getxoffset() {         // center marker-view horizontally         return -(getwidth() / 2);     }      @override     public int getyoffset() {         // cause marker-view above selected value         return -getheight();     } } 

i have linechart wrapped inside vertical linearlayout other elements , whole thing wrapped inside scrollview. not sure if that's what's causing problem or not.

nevermind, figured out. it's because library downloaded maven , gradle not same 1 included in example project on website.
