public String Title {get; set;}
Remarks
By default, Title is empty.
Every Series has a Title property of type String. The Title property is used in TChart.Legend to draw the series descriptions. If Title is empty, then the Series class Name will be used to draw the legend. Setting Title both at design time and runtime will force the Chart to repaint.
Example
[C#]
tChart1[0].Title = "Total Population";
