Custom-Graph-2D-plots-in-javafx

A custom graph library , to draw clean 2D plots in a JavaFX canvas.

Common features:

1.You can draw line and pie graph/chart 2.Multiple line graph in one chart 3.Different colours for, different lines(you can refer image-responseOneupdated) 4.Powerful accurate geometrical/mathematical tools are added(For example- You can find respective x value for y value)

#How to use

    //create the objects for both classes
    
    GraphBuild c=new GraphBuild();
    XYPoints xy=new XYPoints();
    
    xy.add(7,-1);xy.add(-7,2);xy.add(-10,-15);
    xy.add(-10,-15);xy.add(70,-10); //add the points of x and y
    
    //set the line allignement in graph
    xy.setHorizontal(true);
    
    //plot the 2d graph
    c.Scalexy(xy);
    c.linedraw(xy);
    
    Canvas thisCanvas=c.getCanvas();
    
    //refer response 1
    --------------------------------------------------------------------------
    
    
    
    //if
    xy.setVertical(true);
    
    //refer response 2
    --------------------------------------------------------------------------
    
    
    
    
    //if you add
    c.enableZero();
    
    //refer response 3 for with this parameter
    //refer response 4 for without this parameter
    
    --------------------------------------------------------------------------
    
    
    //you can use it with Luiz Felix's parser library
    
    JParser f=JParser.getInstance();
    
    try {
        for(int i=0;i<100;i++){
        f.setVariable(i*0.1);
        f.compileExpression("sin(x)");
        
        }   
    } catch (Exception ex) {
    }
    
    //refer reponse 5
