General Properties

ActiveInvisible	Byte	Usually the graph does not load data or draw if it cannot be seen. However, if you need it to draw regardless (typically so you can save it to a file), then set this property to 1.
BackgroundColor	Long	The color to use as the wallpaper for the graph. Defaults to COLOR:Silver. This property is ignored if the BlackAndWhite property is set.
BackgroundShadeColor	String(255)	If this is set to a value >= 0, the background is shaded from BackgroundColor on the left to BackgroundShadeColor on the right. This property is ignored if the BlackAndWhite property is set.
BackgroundPicture	Long	A BMP file to use as the wallpaper for the graph. This property is ignored if the BlackAndWhite property is set.
BorderColor	Long	The color of the border around the graph. Defaults to Color:Black.
Control	Long	The bounding control (graph region) )equate. Charts will be drawn within the bounds of this control.
Depth	Long	The 3D depth of the chart (in 1/1000 inch).
MinPointWidth	Long	If you have a large number of points on the graph, then naturally each point for the graph is very very small. This is not terribly useful, and can also make the graph look bad if each point is labeled. Setting this property allows you to set the minimum space (in pixels) occupied by each x-axis point. The graph workspace is adjusted accordingly - the region size will remain the same, but scrollbars may appear.
MouseMovePointValueFormat	String(50)	When your mouse moves over the graph, it is possible to display information relating to the data point your mouse is over somewhere on your window or on a tooltip. Use this property to specify the format in which the x-axis point value should be displayed.
Points	Real	The number of data points to plot. (This does not apply to Time charts). Note that this property is mostly for internal use.
PrintPortrait	Byte	Set this to 1 if you want your graphs to print out in portrait style as opposed to landscape.
ReportBand	Long	The target band on the report. This will be cleared after each call to Draw()
SavedGraphType	Long	The graph type selected by the user the last time the application was closed.
SumariseAllSets	Byte	By default this is set to 1. When the .GetPointSummary() method is called, all sets on the graph will be included in the summary. However, if this property is off, only the set over which the mouse is will be included.
SuppressBusyWindows	Byte	By default, when the .PrintGraph() method is called, a small PRINTING message is displayed. If you want to suppress this message then set this property to 1.
Type	Long	The type of chart. Valid options are Insight:Line, Insight:Bar, Insight:Pie, Insight:Time, Insight:Gantt, Insight:Scatter and Insight:Pareto.
UnlockThreadForPrint	Long	Unlock the thread before printing starts. Basically, set this to 0 this if you are using FixIT and your other threads freeze when you print the graph. Init() sets this to 1.
WriteLog	Byte	If this is set to 1 then debugging information is written to the SysInternals DebugView program.
OpenText, CloseText, HighText,LowText	String(20)	These properties contain the text, used when the tooltip for a Floating Bar or HiLo graph. They default to 'Open:', 'Close:', 'High:' and 'Low:' respectively.

Data Display Properties

AspectRatio	Real	For 2D pie charts, if this is set to 1 the pie will always be circular (as opposed to elliptical).
AxisStyle	Byte	For "built-in" graph styles (for the axis). To set the style use the .SetStyle() method, with the style type set to Style:Axis.
BlackAndWhite	Byte	Set this property if the graph must only use black and white colors when drawing. Mostly used when printing to black and white printers.
DataStyle	Byte	For "built-in" graph styles (for the data). To set the style use the .SetStyle() method, with the style type set as Style:Data.
DrawMissing	Byte	Draw through data points not supplied. (Line charts)
Fill	Long	The area below the data points will be filled (Line and Time charts)
FillToZero	Long	The area between the data points and the Zero mark will be filled (Line and Time charts)

InnerRadius	Long	This is the value (as a percentage from 0 to 100) of the inside radius of the donut (pie charts only)
LineStyle	Long	The style to use for drawing the Line. Valid options are Pen:Solid, Pen:Dash, Pen:Dot, Pen:DashDot and Pen:DashDotDot
LineWidth	Long	The line width to use for data display. For example, for lines this will be the width of the line. For bars, this will be the width of the bar outline.
MaxPieRadius	Long	Sets the maximum radius of the Pie graph, in pixels. Useful on reports where you are trying to make several pie graphs all look the same size.
Pattern	Byte	Set this to Insight:Auto so that each set is assigned a default pattern. Set to Insight:None if the graph does not use patterns. If a pattern is specified here, all sets will be assigned this default pattern. For a list of patterns, see the Pattern entry of the Properties Tab in the Template Guide.
PieAngle	Real	Set this to the angle (in degrees) at which you would like the first pie slice to be drawn. 0 degrees is at 12 o-clock, and the angle increases in a clockwise direction from there.
PieLabelLineColor	Long	Set this to the color you would like the lines connecting each label to its respective pie slice to be.
PointWidth	Real	The width the data point display should occupy of the allocated point display width.
Shape	Byte	Defaults to Insight:Auto. This property can be overridden at the Set level (see the Shape entry for the SetQ). Applies to Line and Scatter graphs. Set to Insight:None to suppress shapes on Line graphs.
SortSet	Long	The data set to sort on for pareto charts.
SortStyle	Long	The sort style. 0=none, 1 = high value on bottom and -1 = high value on top.
SquareWave	Byte	Set the default for the lines on the graph to be square waves.
Stacked	Byte	For data value stacking (bar, line and pareto charts). Set to 1 or 0.
StackLines	Byte	When this is switched on, line graphs (and scatter graphs) will be stacked if the Stacked property above is switched on. Otherwise, line graphs wont be stacked. Default value is 1 (assigned by .Init()).

Note: Note that there are a maximum of 3 strings that can be displayed in the label - ShowDataLabelText, ShowDataLabelValue and ShowDataLabelPercent. Hence, if you for example choose PieLabelLines to be 3 and you only have 2 of the ShowDataLabelText, ShowDataLabelValue and ShowDataLabelPercent properties set to 1, there will be empty lines in the labels.
PiePercentFormat	String(50)	When ShowDataLabelsPercent is on, use this to specify the format you want the percentage value to be displayed in. When left empty, a default format is used.

If Scale:Low or Scale:High is omitted, then the value in YAxisMin and/or YAxisMax will be used. If Scale:Zero is used, then the scale will be adjusted to include zero. To disable auto scaling, set this property to Scale:None.
PercentSetNum	Long	If you want the data to be displayed as percentage values on the y-axis and you want a set's value at each x-axis point to be used as the total for calculating those percentages, set this to the number of that set . If you don't want this set to be visible (typically you wouldn't, as it will be 100% at each x-axis point), just make it invisible.

ShowToPointTime	Real	Time point to show to (Time charts). Mostly for internal use (see .Zoom()).
WorkSpaceWidth	Long	The graph's width and height defaults to the control size on the window. However, since Clarion supports scroll bars on a control, there may be cases when you want the graph to be bigger than the control. In this case, somewhere after the call to the .Init method, set the WorkSpaceWidth and WorkSpaceHeight properties. Scroll bars will be automatically added but OUTSIDE the space you've allocated to the control. So if you intend to have scrollbars, make sure you have sufficient space for them.

ZoomPoint	Real	The x-axis point which is being zoomed in to. Mostly for internal use (see .Zoom()).

Set Properties

Each data set has a number of properties that affect just this set. Although these properties can be read and written directly, where a method is supplied it is recommended that it be used to set the property.

Some of the properties override Graph Level properties, and some of the properties in turn can be overridden at the Data Level.

Use the .GetSet() method to get the correct queue entry for the set you want to edit. For example:

If ThisGraph.GetSet(n)
ThisGraph.SetQ.Property = x
Put( ThisGraph.SetQ)
End

where n is the set number and x is the value you want to set the property to.

Set	Long	The set number. Ideally starts with 1 for the first set, and goes up by 1 for each set (however, random numbers may also be used). Each set has a unique number. You can use the .AddSetQ() method to add a new set. You can use the .GetSet() method to load a set record. Notice that a pie graph will only ever have one set, and that this set number should always be set to 1.
DataLabelFormat	String(50)	A picture format used when writing the data labels for this set, e.g. @n12.2. If this is left blank, the DataLabelFormat will be used.
LabelDataStartPosition	Long	Setting this to n will cause the data labeling for this set to only start at the n'th x-axis point.
NoDataLabels	Byte	Set to True or False. Allows you to suppress the data labels for this set.
NoYAxisLabels	Byte	Set to True or False. Allows you to suppress the y-axis labels for this set (if SeperateYAxis is on). Typically used when another set has the same labels.
SetDescription	String(100)	The description of the set. This is used when setting the legend text and the point summary information. See .SetSetDescription().
ShortYAxisLabels	Byte	Set to True or False. See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
ShortYAxisLabelsUnit	Byte	Set to True or False. See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
YAxisFormat	String(50)	A picture format used when writing the Y-Axis labels for this set. e.g. @n2.2
The following properties override the ones set at Graph Level.
AutoScale	Byte	This is a composite number (via addition) made up of Scale:None and Scale:Low + Scale:High + Scale:Zero. See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
Type	Long	Allows you to change the graph type of this set so that you can, for example, include a Line in a Bar chart. See .SetSetType()
Fill	Long	Applies only to Line graphs. If set to 1 then the area under the graph will be "filled". If set to -1 then the default for the graph is used.
FillToZero	Long	Applies only to Line graphs. If set to 1 then the area between the graph and the Zero mark (on the y-axis) will be filled. If set to -1 then the default for the graph is used.
MouseMoveFormat	Byte	Specifies the format the y-axis values for this set in the mouse-over information should be displayed in.
Points	Long	Limits the set to the first n points (i.e. only the first n points of the set will be plotted on the graph). e.g. Useful for graphing the "top ten".
SquareWave	Byte	Applies only to Line graphs. If set to , the line will be drawn in a square format. If set to -1 then the default for the graph is used.
YAxisMax	Real	See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
YAxisMin	Real	See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
YAxisStep	Real	See the entry with the same name under Y-Axis Properties (only useful if SeperateYAxis is on).
The following properties override the graph level, and can be overridden at the data level.
PenColor	Long	The pen color used for drawing this set. See .SetSetColors().
FillColor	Long	The fill color used for drawing this set. See SetSetColors().
ShadeColor	Long	The shade color used for drawing this set. See SetSetColors().

LineWidth	Long	Sets the line width used when drawing this set.
PointWidth	Real	Specifies the width of the bar in proportion to the space between bars at a given x-axis point. Is a percentage where 100 means bars touch, and 50 means that there is 1 bar with between bars.
Pattern	Byte	Sets the pattern for this particular set. Use Insight:Auto to use the default pattern for this set.
Shape	Byte	Sets the Shape for this set. Applies to Line and Scatter graphs. Use Insight:Auto to use the default shape for this set. Other valid options are Insight:None, Insight:Square, Insight:Circle, Insight:Triangle, Insight:Diamond.
Visible	Byte	Set to True or False. Default is True. If set to false then this set is ignored when drawing the graph. Useful when you want to offer the user the ability to turn sets on and off at runtime.

Data Properties

The data that Insight actually graphs is stored in the DataQ property. This is a Queue with the following fields. Accessing the Data Queue is not usually done directly, but nothing stops you. The usual method for adding items to the DataQ is the .Data() method.

Set	Long	The set number of the set that the data point belongs to.
Count	Long	This is an internal property that is set by .ResetQueue(). It holds the number of child records for this data point.
Point	Real	The point number for this data point. For normal graphs this is an incrementing integer, usually starting at 1. For time graphs it is a real with the format date + time, e.g. dataq.point = Date + (Time / 8640000).
ValueMin	Real	For floating bars, this is the y-axis value for the bottom of the bar.
ValueMax	Real	This is the data value (where the point should be plotted on the y-axis).

Visible	Byte	Set to True or False. Default is True. If set to false then this data point is ignored when drawing the graph. Useful when you want to offer the user the ability to turn points on and off at runtime.

Label Properties

The details for each label on the x- and y-axis are stored in a queue called the labelq. Typically, you would want to leave this queue alone, unless you want certain labels on the x- or y-axis to stand out, for example, by editing the font. You would put your code to do this in the SetLabelFonts() procedure. Your code would look something like this:

loop counter = 1 to records(self.LabelQ)
   get(self.LabelQ, counter)
   if errorcode()
     cycle
   end
   self.LabelQ.FontName = ''
   self.LabelQ.FontSize = 0
   self.LabelQ.FontColor = -1
   put(self.LabelQ)
end

loop counter = 1 to records(self.LabelQ)
   get(self.LabelQ, counter)
   if errorcode()
      cycle

Low Level Drawing Methods

Note: Many of the low-level drawing commands take co-ordinates (x,y, width, height and so on.) You should, wherever possible, draw using relative co-ordinates, not fixed co-ordinates. If you draw with fixed co-ordinates, then the items will not scale well if the user chooses to print the graph (right-click print) or if the graph is rescaled on the window. By drawing with relative co-ordinates your drawing will scale better.
