Gigasoft.ProEssentials.Pego.PeData Members

Only used in a Real-Time implementation. Gets or Sets whether data is appended to end or beginning of memory. See also: AppendYData.

Gets and Sets whether large/small data will be displayed with a scale factor. For example, a grid line value of 10,000,000 may be displayed as 10M if this property is true. M representing millions.

Used with Data.DateTimeMode = True. This property controls whether ProEssentials includes Saturdays and Sundays in automatically generated Data.X or Data.Xii.

This property enables DateTimeMode. This mode treats X axis data as serially formatted date/time data.

If Data.DateTimeMode is True, and data is exported via export dialog, this property controls whether seconds are included in time export. Also controls the data cursor prompt in top-left corner if shown.

Used with Data.DateTimeMode = True. This property defines the number of data points per day. If Data.DeltaX is less than zero than this property is not used. See help for more info.

Used with Data.DateTimeMode = True. This property defines the distance in time between each data point. DeltaX greater than 0 for time in minutes. DeltaX = 1 for daily data, DeltaX = 2 for weekly data, DeltaX = 3 for monthly data.

Set to true when RenderEngine = Direct3D and a real-time implementation will need to incrementally change data. Used in conjunction with properties RealTimeStartingIndex, RealTimeQuantity. These features are added to implement a chart with a very large amount of data, that needs to be updated incrementally but rapidly. Historically, for large data sets, the chart would become slower as more data was rendered causing the system to become less responsive over time. These new features avoid this concern. The one draw back to this feature is DynnamicBuffers cause an extra delay upon initial initialization of the Direct3D buffers.

Gets and Sets data reduction strength. Default=Quality. Setting to fastest setting could possibly degrade for scatter type charts but actually should be fine for most charts drawn left to right.

Read only. True if image is a product of data reduction. PeData.Filter2D or PeData.Filter3D and Subsets/Points and size of chart all effect if FilterOn is True.

Gets and Sets the YData value considered null and subsequently ignored.

ProEssentials Data Object interface. Used for incremental-data / real-time / strip-chart internet updating.

Always set this property prior to passing Data.Y and/or Data.X. Gets or Sets quantity of data points per series. Example: for a line chart, this is the number of data points per line.

Set or Get the precision used within table, on-screen coordinate prompting and data exporting.

Gets or Sets points to be included in image. Fill this array with zero based point indices of those points you wish to include in the image. Use RandomPointsToGraph.Clear() to show all points again.

Gets or Sets subsets to be included in image. Fill this array with zero based subset indices of those subsets you wish to include in the image. Use RandomSubsetsToGraph.Clear() to show all subsets again.

Used when RenderEngine = Direct3D and DynamicBuffers set to True. Within the chart update event/timer logic, the developer will set this property to coincide with the quantity of new data indices updated. See example 138 in the demo/example project. This is a fairly specific use so your implementations will need to mimic example 138 closely. All subsets will be redrawn for the point range defined by RealTimeStartingIndex and RealTimeQuantity.

Gets the current scale factor as a power of 10 for the Right Y Axis. Only used if Data.AutoScaleData = True.

Gets the current scale factor as a power of 10 for the Y Axis. Only used if Data.AutoScaleData = True.

Gets and Sets if data can potentially be optimized. Default=Auto. This setting can be used to disable or force filtering. Most likely you may need to disable in some rare types of implementations.

Gets and Sets speedboost value. Default is 3. Valid range is 1 to 100 but best results are produced with values less than 30. This feature will attempt to reduce GDI LineTo calls by eliminating calls where the line only moves slightly from its previous position.

This property sets the starting date and daily start time when used in conjunction with Data.DateTimeMode, Data.AutoXData, Data.DeltaX, and Data.DeltasPerDay. It is important that this value include the date value along with time.

Gets and Sets how two dimensional property arrays (example, Data.Y, Data.X) are stored internally. If you will be adjusting the number of Subsets and/or Points and want to preserve existing data, read the help on this property.

Always set this property prior to passing Data.Y and/or Data.X. Gets or Sets quantity of data series. Example: for a line chart, this is the number of lines with different colors.

This property array makes it easier to select which subsets are visible. It also has a second optional ability to control the order of how subsets are drawn.

If setting this property, set it before passing data. Gets and Sets whether single or double precision data is utilized. Set to true to use double precision (Data.Xii) instead of (Data.X).

If setting this property, set it before passing data. Gets and Sets whether single or double precision data is utilized. Set to true to use double precision (Data.Yii) instead of (Data.Y).

You must set Data.Subsets and Data.Points before passing this data. Gets or Sets single precision data plotted with respect to x axis. PieChart (Pepco) uses this for controlling slice size. Pego only uses x data for Date-Time handling.

You must set Data.UsingXDataII=true, Data.Subsets and Data.Points before pass this data. Gets or Sets double precision data plotted with respect to x axis. Pego object only uses xdata for DateTime handling.

You must set Data.Subsets and Data.Points before passing this data. Gets or Sets single precision data plotted with respect to y axis.

You must set Data.UsingYDataII=true, Data.Subsets and Data.Points before pass this data. Gets or Sets double precision data plotted with respect to y axis.

You must set Data.Subsets and Data.Points before passing this data. Gets or Sets single precision data used with floating bar charts.
