teechart - Delphi: discrete bottom axis in TChart -

i'm not able implement discrete bottom axis tchart (i'm using lite version in xe5)

my purpose display 2 series: series1 : tbarseries, series2: tlineseries scalar

in chart bottom axis discrete (integer values or date)!

adding these values (for example)

series1.addxy(0,2,'',clgreen); series2.addxy(0,5,'', clred);  series1.addxy(1,4,'',clgreen); series2.addxy(1,5,'', clred);  series1.addxy(2,6,'',clgreen); series2.addxy(2,2,'', clred); 

the chart drawn follows:

but, can see, bottom axis not discrete. want obtain this

how can achieve that? thank you.

i've made simple example using tareaseries , tlineseries, both stairs , think looks you'd to:

uses series;  procedure tform1.formcreate(sender: tobject); const values0: array[0..2] of tchartvalue = (2, 4, 6);       values1: array[0..2] of tchartvalue = (5, 7, 2); var i: integer; begin   chart1.view3d:=false;   chart1.legend.visible:=false;    chart1.addseries(tareaseries) tareaseries   begin     color:=clgreen;     stairs:=true;     useyorigin:=true;   end;    chart1.addseries(tlineseries) tlineseries   begin     color:=clred;     stairs:=true;   end;    i:=0 high(values0)   begin     chart1[0].addxy(i-0.5, values0[i]);     chart1[1].addxy(i-0.5, values1[i]);   end;    chart1[0].addxy(chart1[0].count-0.5, values0[chart1[0].count-1]);   chart1[1].addxy(chart1[1].count-0.5, values1[chart1[1].count-1]); end;
