The grapher is a sister component of the main interface and can be launched from the main interface using the file menu system. It can also be launched by the user entering the plot command on the command line. This will execute a new dialogue box where the graph will be displayed. Hence the Grapher, will give provide the ability to graphically represent data or functions provided by the user at the command line.
To plot a new graph the user would need to define two data series. These data series can be placed into two variables but must be inputted in matrix form. One the data series are set then they can be plotted by using the plot command. When the plot command is executed it will open a new graph dialog box and the graph will be plotted within this box. The plot dialog box can also be opened by going to the file new menu system as well. This will open a dialog box where the data from the main interface can be placed in.
Example:
plot(A,B)
(A and B are two sets of data series that have been already defined
in matrix form).
The chart labels can be edited by going to the chart area menu in the grapher and clicking upon label chart. This is initiate a dialog box where the title and x and y axis of the chart can be labelled. By entering the correct data the chart will be refreshed with the new labels.
The background colors of the chart can be changed by going to the chart area menu and clicking on the change color menu. This will open a dialog box where the color of the background can be chosen. Once the color has been chosen this will become the background color.
The Think++ has an
export facility to export the graph to different formats. The graph can
be exported to jpeg, bitmap, gif and various other formats. This can be
done by creating the graph and then under the file menu choosing the export
option. This will allow the graph to be exported under different image
formats.
