Data

FindGraph  saves data in its own format.  WINDOWS registers format (extension 'fgr') as 'FindGraph.Document'. The document includes the arrays of objects:

There are no formal limitations on quantity of objects. All objects of the program can be exported to XML file.

Series of points

Each point of a series has three parameters (double 8 bytes): X and Y in physical units of axes and Z.  There are no formal limitations on quantity of points.

Parameter Z
  • The number to keep weight and error bars,
  • The current local time hour:min:sec;msec,
  • The number of milliseconds that have elapsed since the series was started.
In calculations Z is used only as weight.

The parameters of series:

There are different ways to collect points:

Use the Information dialog to change the parameters of series and to sort the points of series. Use the Text editor  to edit X, Y, Z values. The points can be moved and erased with Editor.

The program allows different ways to export information about points to the other programs and files:

 

Areas

The area is determined by physical coordinates (X, Y) of marks. The parameters of area:

There are two ways to create an area:

When paint, you can fill areas with color and  hide the marks. Use the Information dialog to change the parameters.

The areas will be used:

 

Functions

The approximation is build on points you selected or on series of points. The parameters of function:

Use the Information dialog to change the parameters .

 

Commentaries

The parameters of commentary:

Use the Information dialog to change the parameters.  The coordinates of commentary are in physical units and are recalculated when scaled.

The commentary can be paint as distributed under the document text. See the sample how to add a commentary.
