The Copy Constructor.

The Axis object from which to copy

Implement the interface in a typesafe manner by just calling the typed version of Clone.

Note that this method must be called with an explicit cast to ICloneable, and that it is inherently virtual. For example:

AxisChange causes the axes scale ranges to be recalculated based on the current data range.

There is no obligation to call AxisChange() for manually scaled axes. AxisChange() is only intended to handle auto scaling operations. Call this function anytime you change, add, or remove curve data to insure that the scale range of the axes are appropriate for the data range. This method calculates a scale minimum, maximum, and step size for each axis based on the current curve data. Only the axis attributes (min, max, step) that are set to auto-range (, , ) will be modified. You must call after calling AxisChange to make sure the display gets updated.
This overload of AxisChange just uses a throw-away bitmap as Graphics. If you have a Graphics instance available from your Windows Form, you should use the overload instead.

Hue-Saturation-Brightness Color class to store a color value, and to manage conversions to and from RGB colors in the struct.

This class is based on code from http://www.cs.rit.edu/~ncs/color/ by Eugene Vishnevsky. This struct stores the hue, saturation, brightness, and alpha values internally as values from 0 to 255. The hue represents a fraction of the 360 degrees of color space available. The saturation is the color intensity, where 0 represents gray scale and 255 is the most colored. For the brightness, 0 represents black and 255 represents white.

The color hue value, ranging from 0 to 255.

This determines if the curve will be drawn by directly connecting the points from the data collection, or if the curve will be a "stair-step" in which the points are connected by a series of horizontal and vertical lines that represent discrete, staticant values. Note that the values can be forward oriented ForwardStep () or rearward oriented RearwardStep. That is, the points are defined at the beginning or end of the staticant value for which they apply, respectively.

Gets or sets a property that determines the smoothing tension for this . This property is only used if is true. A tension value 0.0 will just draw ordinary line segments like an unsmoothed line. A tension value of 1.0 will be smooth. Values greater than 1.0 will generally give odd results.

A floating point value indicating the level of smoothing. 0.0F for no smoothing, 1.0F for lots of smoothing, >1.0 for odd smoothing.

Determines if the will be drawn by directly connecting the points from the data collection, or if the curve will be a "stair-step" in which the points are connected by a series of horizontal and vertical lines that represent discrete, constant values.

enum value

Gets or sets the data for this .

Gets or sets a boolean value that determines if this will be drawn with optimizations enabled.

Normally, the optimizations can be used without a problem, especially if the data are sorted. The optimizations are particularly helpful with very large datasets. However, if the data are very discontinuous (for example, a curve that doubles back on itself), then the optimizations can cause drawing artifacts in the form of missing line segments. The default option for this mode is false, so you must explicitly enable it for each LineItem.Line. Also note that, even if the optimizations are enabled explicitly, no actual optimization will be done for datasets of less than 1000 points.

This method just handles the case where one or more of the coordinates are outrageous, or GDI+ threw an exception. This method attempts to correct the outrageous coordinates by interpolating them to a point (along the original line) that lies at the edge of the ChartRect so that GDI+ will handle it properly. GDI+ will throw an exception, or just plot the data incorrectly if the coordinates are too large (empirically, this appears to be when the coordinate value is greater than 5,000,000 or less than -5,000,000). Although you typically would not see coordinates like this, if you repeatedly zoom in on a ZedGraphControl, eventually all your points will be way outside the bounds of the plot.

Gets or sets a value that determines if the polygon will be automatically closed. true to close the figure, false to leave it "open."

This boolean determines whether or not the CloseFigure() method will be called to fully close the path of the polygon. This value defaults to true, and for any closed figure it should fine. If you want to draw a line that does not close into a shape, then you should set this value to false. For a figure that is naturally closed (e.g., the first point of the polygon is the same as the last point), leaving this value set to false may result in minor pixel artifacts due to rounding.

Add a set of values onto the head of the queue, overwriting old values if the buffer is full.

This method is much more efficient that the Add(PointPair) method, since it does not require that a new PointPair instance be provided. If the buffer already contains a at the head position, then the x, y, z, and tag values will be copied into the existing PointPair. Otherwise, a new PointPair instance must be created. In this way, each PointPair position in the rolling list will only be allocated one time. To truly be memory efficient, the , , and methods should be avoided. Also, the property for this method should be null, since it is a reference type. The X value The Y value The Z value The Tag value for the PointPair

A value less than zero is left of the ChartRect and a value greater than 1.0 is right of the ChartRect. For the Y coordinate, the value just corresponds to the values of the Y2 scale. Values outside the scale range will be outside the .

Enumeration type that defines how a curve is drawn. Curves can be drawn as ordinary lines by connecting the points directly, or in a stair-step fashion as a series of discrete, constant values. In a stair step plot, all lines segments are either horizontal or vertical. In a non-step (line) plot, the lines can be any angle.

Draw the as a stair-step in which each point defines the beginning (left side) of a new stair. This implies the points are defined at the beginning of an "event."

Draw the as a stair-step in which each point defines the end (right side) of a new stair. This implies the points are defined at the end of an "event."

Draw the as an ordinary line, in which the points are connected directly by line segments.

Draw the as a segment in which each point defines the beginning (left side) of a new "stair." This implies the points are defined at the beginning of an "event." Note that ForwardSegment is different from ForwardStep in that it does not draw the vertical portion of the step.

Draw the as a segment in which each point defines the end (right side) of a new "stair." This implies the points are defined at the end of an "event." Note that RearwardSegment is different from RearwardStep in that it does not draw the vertical portion of the step.

Enumeration type that defines the base axis from which graphs are displayed. The bars can be drawn on any of the four axes (, , , and ).

Draw the chart based from the .

Enumeration type that defines the available types of graphs.

Draw the lines as normal. Any fill area goes from each line down to the X Axis.

Draw the lines stacked on top of each other, accumulating values to a total value.

Enumeration type that defines the available types of graphs.

Draw each side by side in clusters.

Draw the bars one on top of the other. The bars will be drawn such that the last bar in the will be behind all other bars. Note that the bar values are not summed up for the overlay mode. The data values must be summed before being passed to . For example, if the first bar of the first has a value of 100, and the first bar of the second has a value of 120, then that bar will appear to be 20 units on top of the first bar.

Draw the bars one on top of the other. The bars will be drawn such that the bars are sorted according to the maximum value, with the tallest bar at each point at the back and the shortest bar at the front. This is similar to the mode, but the bars are sorted at each base value. The data values must be summed before being passed to . For example, if the first bar of the first has a value of 100, and the first bar of the second has a value of 120, then that bar will appear to be 20 units on top of the first bar.

Draw the bars in an additive format so that they stack on top of one another. The value of the last bar drawn will be the sum of the values of all prior bars.

Draw the bars in a format whereby the height of each represents the percentage of the total each one represents. Negative values are displayed below the zero line as percentages of the absolute total of all values.

Enumeration type that defines which set of data points - X or Y - is used to perform the sort.

Use the Y values to sort the list.

Use the X values to sort the list.

Enumeration that specifies a Z-Order position for objects.

This enumeration allows you to set the layering of various graph features. Except for the objects, other feature types all have a fixed depth as follows (front to back): objects The border around objects The features The background fill of the The pane The background fill of the You cannot place anything behind the background fill, but allows you to explicitly control the depth of objects between all other object types. For items of equal , such as multiple 's or 's having the same value, the relative depth is controlled by the ordinal position in the list (either or ). objects can be placed in the of either a or a . For a -based , all values are applicable. For a -based , any value can be used, but there are really only three depths: will place the item behind the pane title, will place on top of all other graph features, any other value places the object above the pane title, but behind the 's.

Specifies that the will be behind all other objects (including the ).

Specifies that the will be behind the background (see ).

Displays for a slice in a Pie Chart.

No label displayed.

Define the auto layout options for the method.

Layout the 's so they are in a square grid (always 2x2, 3x3, 4x4), leaving blank spaces as required.

For example, a single pane would generate a 1x1 grid, between 2 and 4 panes would generate a 2x2 grid, 5 to 9 panes would generate a 3x3 grid.

Layout the 's so they are in a general square (2x2, 3x3, etc.), but use extra columns when necessary (row x column = 1x2, 2x3, 3x4, etc.) depending on the total number of panes required.

For example, a 2x2 grid has four panes and a 3x3 grid has 9 panes. If there are 6 panes required, then this option will eliminate a row (column preferred) to make a 2 row x 3 column grid. With 7 panes, it will make a 3x3 grid with 2 empty spaces.

This struct encapsulates a date and time value, and handles associated calculations and conversions between various formats.

This format stored as a double value representing days since a reference date (XL date 0.0 is December 30, 1899 at 00:00 hrs). Negative values are permissible, and the range of valid dates is from noon on January 1st, 4713 B.C. forward. Internally, the date calculations are done using Astronomical Julian Day numbers. The Astronomical Julian Day number is defined as the number of days since noon on January 1st, 4713 B.C. (also referred to as 12:00 on January 1, -4712). NOTE: MS Excel actually has an error in the Serial Date calculations because it errantly assumes 1900 is a leap year. The XDate calculations do not have this same error. Therefore, XDate and Excel Date Serial values are 1 day different up until the date value of 60 (in Excel, this is February 29th, 1900, and in XDate, this is February 28th, 1900). At a value of 61 (March 1st, 1900) or greater, they agree with eachother. John Champion $Revision: 3.23 $ $Date: 2007-11-11 06:56:34 $
