To plot a graph...
First of all ensure that you know what exactly type of graph you want to plot (i.e. common y(x) or x(y) Cartesian Graph, Polar, Paramentric or Table Defined one). Let it be polar graph for example. Select then the Graphics|New|Polar Graph... main menu command. The Polar Graph dialog box will appear prompting you to enter the formula for your graph and adjust its color, line style, interval etc. You may use any valid mathematical expression involving constants when typing a formula. After you close the dialog box by clicking the OK button your graph will be plotted in a coordinate plane.

To place text on the plot...
To add some text to the coordinate plane select the Graphics|New|Label... main menu item. This will show the Label dialog box allowing you to type the text itself, set its color, font, style and position in the space. Position is determined by two (X, Y) coordinates which can be any any valid mathematical expressions involving constants. After you close the dialog box by clicking the OK button the text caption will be plotted in a coordinate plane. There is a possibility to drag&drop a text label using mouse. To avoid its occaisional movements just lock it. This can be easily done by going to the Label dialog box and setting the Locked box on.

To import data for Table Graph...
To import data for a table defined graph first create one by going to the Graphics|New|Table Graph... GraphSight main menu option. The Table Graph dialog will appear. Navigate to the Data tab and click the Action|Import option. You will be prompted with a standard Open dialog which lets you choose the file to import data from. The file is expected to be in the following format:

x.xx, y.yy
xx.x, y
xxxx, yyyy

In other words each line of a file being imported must consist of pairs of x and y values separated by comma. Decimal separator must be the "." sign.

To fit experimental data...
Curve fitting refers to fitting curved lines to data. The curved line comes from regression techniques, a spline calculation, or interpolation. The data can be measured from a sensor, generated from a simulation, historical. The goal of curve fitting is to gain insight into your data, to generate a curve (a formula) that is closer to the experimental data as much as possible. GraphSight provides a possibility to do curve fitting using different regression models (reciprocal, gauss, hyperbolic, linear, logarithmic, polynomial). To do curve fit first create a Table Graph by choosing the Graphics|New|Table Graph item from the programs main menu. The Table Graph dialog will appear. Import your data by going to the Data tab and choosing the Action|Import option. Unselect the Show lines box and press OK button to apply changes and close the dialog. You will see data points plotted on the coordinate plane. Click one to make all selected. Choose the Graphics|Tools|Fit GraphSight main menu option. This will apply the Fit tool to the graph. After going through the Fit tool wizard you will get the desired fitting curve.

To navigate through the coordinate plane...
GraphSight gives you full control over the cordinate plane. To move the coordinate plane in any direction you want just hold the left mouse down while moving it. The coordinate plane will shift. To make the coordinate plane zoom just hold the right mouse button pressed while moving it over the spaces background. If you have a wheel-staffed mouse then rotating the wheel will also lead to the coordinate plane zoom. To set spaces dimensions exactly just modify its range variables through the Space dialog box.
There is a possibility to save current view (proportions, zoom factor, the origin, etc.) of a coordinate plane to be able to return to it whenever needed. This may be useful when your shift & zoom activities has led to distorted look of the graphs and you want to make things back. Use the Space Views window on the left to manage space views. Double-clicking a view in the list will restore it. A space always has the inital (the default) view which can never be deleted. Each space posesses its own set of views.

To trace a graph...
Tracing a graph means simply a posibility to visualy observe how the function Y(X) depends on the variable X. It also makes it easy to know the exact function value for the exact value of the parameter. GraphSight lets you trace all the graphs except table-defined (data driven) one since tracing is expressed in terms of a functions parameter step-by-step change. This functionality is aplicable to y(x) and x(y) cartesian, polar and parametric graphs only as they are parametric by nature. Let's trace a Polar graph for example. Navigate to the Graphics|New|Polar Graph... main menu option to create the graph. After it is plotted on the coordinate plane, select it with the mouse and go to the Graphics|Tools|Trace... programs main menu option. You will be presented with the Trace tool dialog. Play with settings and enjoy the investigation of a functions behaviour then.

To save a space as an image ...
GraphSight provides an ability to export the current coordinate plane image to a file or clipboard. Navigate to the Space|Export Space Image|Bitmap (.bmp) GraphSights main menu option to save the coordinate plane picture as a bitmap. Selecting the Clipboard item of the menu will store the image in the Windows clipboard thus enabling you to insert it into any other place like Word documents or an Excel sheets.

To customize axes ticks ...
We made our best for the user to avoid boring necessarity of adjusting axes ticks. The are automatically adjusted to fit best view. Although GraphSight provides an ability to do any customization by hand. There are three policies of axes ticks positioning in GraphSight. They are Automatic, Step and Pixels. The Automatic one will cause axes to be positioned automatically at every c * k * 10 ^ n position. The Step option will tick fixed step and the Pixels option will adjust steps to each m pixels. The settings can be applied to each of x and y-axis independently. For more information about ticks customizing please, refer to the axes description.
To set an apropriate mode please select the axes in the coordinate plane or the Project tree with your mouse and choose the Graphics|Properties programs main menu item. You will be presented with the Axes dialog box prompting you to make all necessary customizations (ticks mode, color, width, grid, style and so. on.).

To display the coordinate grid ...
GraphSight provides an ability to display the coordinate grid on the plane. This can be vertical and\or horizontal dashed lines aligned to axes ticks. To show the grid right-click the axes first. After the shorcut menu appears, select the Grid lines|Both menu item and grid will appear. The same action will hide the grid back. Another way is to make the axes selected and navigate to the Graphics|Properties GraphSight main menu item. The Axes dialog box will appear. Select the Grid tab use the appropriate Vertical and Horizontal lines boxes to turn on the grids lines.
