Data type for a point with floating point coordinates X and Y Data structure for a rectangle with floating point coordinates defined by opposite corner points a and b or by a 4-element array Enumeration of elements deciding whether a color will override a brush or pen color. Set of elements deciding whether a color will override a brush or pen color. Dynamic array of records (having integer coordinates) Dynamic array of records (having floating point coordinates) Helper type which allows to interpret a TPoint record as an integer array.For a TPoint variable P, the type-cast TPointBoolArr(P)[b] returns P.X when the boolean variable b is false, and P.Y when it is true. Helper type which allows to interpret a TDoublePoint record as a floating point array.For a variable P, the type-cast TDoublePointBoolArr(P)[b] returns P.X when the boolean variable b is false, and P.Y when it is true. Data type for an interval of floating point numbers.

• FStart: begin of the interval
• FEnd: end of the interval

Defines which information is displayed in the text of a series label

• smsCustom: user-defined
• smsNone: no labels
• smsValue: y value of the series, e.g. '1234'
• smsPercent: percentage of the y value, e.g. '12 %'
• smsLabel: text assigned to the data point, e.g. 'Cars'
• smsLabelPercent: text assigned to the data point, and percentage of the y value, e.g. 'Cars 12 %'
• smsLabelValue: text assigned to the data point, and y value, e.g. 'Cars 1234'
• smsLegend: ?
• smsPercentTotal: percentage and the total of the y values, e.g. '12 % of 1234'
• smsLabelPercentTotal: text assigned to the data point, percentage and total of all y values, e.g. 'Cars 12 % of 1234'
• smsXValue: x value of the data point

Enumeration of two ways how text can be interpreted by TAChart: either directly or as being encoded in HTML.

• tfNormal: Text is taken literally.
• tfHTML: Text is assumed to contain simple HTML markup which is respected by the drawing routines.
