Answer 1

The ChartArea's points automatically gets their proper height based on Chart Control's height.

So, try setting Chart's height as there is no Height property for ChartArea - coz there can be multiple series/chartareas in single Chart Control.

Answer 2

this is what i have done.


[ in loop ]
chartArea[i].Position.Auto =true;
                    
chartArea[i].AlignmentOrientation = AreaAlignmentOrientations.Vertical;
if (i == 0)
       chartArea[i].AlignWithChartArea = chartArea[i].Name;
else
       chartArea[i].AlignWithChartArea = chartArea[i - 1].Name;

now even if i increase the height of chart control all chartareas getting big size but it is not allowing more chart areas, and if i remove " chartArea[i].AlignWithChartArea" property setting, charareas are coming but if more than 3 chartarea then 2nd column likewise...

my exact requirement  is to get all the chartareas in single column only with scrollbar, irrespective of number of chartareas.

Explicitly set the position of each chart area the way you want using ChartArea.Position . You have to manually increase the size of the chart using Chart.Height each time you add a chart area if this is what you want.

This thread already has the answer you want along with an example.
