Using values to create a scatter plot in a character array

Question

Ok, I am fairly new to the language and i am working ona program that will first, get the users input of how many values and the x and y of each value, it will store it into a 2d array and also have the x-squared value and X*Y value. I have all the entry of the data working and the calculation for the line of best fit works correctly.
What i need help with is, I want to take those values and store them into a character array that will display the points where they belong with a '*'. I also need to make the graph lines on the left and bottom. If the values are less than 10 for the x or y, i need to make them 10. The Y line needs to be rounded to the next highest 10s place if its over 10. I have tried a few things and i realised that it is completly wrong..
public void graph(int[][] grid, int n)
            int highY = 0;
            for(int x=0;x<n; x++)
             if (grid[x][1] > highY)
                highY = grid[x][1];
         char[][] output = new char[n+1][highY+1];
         for(int z=0; z<highY+1; z++)
             output[z][0]='+';
         for(int w=0; w<n+1; w++)
             output[n][w]='+';
         int tempx=1; int tempy=1;
         output[tempx][tempy]='*';
         while(tempx<n+1)
             tempy++;
             if(tempy==highY+1)
                 tempx++;
                 tempy=0;
             output[tempx][tempy]='*';
         System.out.println();
           for (int I=0; I<n+1; I++)
                  for (int J=0; J<highY+1; J++)
                      System.out.print(output[I][J]);
                      System.out.println();
}Grid is the grid of the values, and for the [x][1] is all the Y values going down, [x][0] is the X values. the x would go up to however many values there are. Again, i know the code above is wrong.
Any thoughts or suggestions would be appreciated. Also, if you need any more info from what i have done please ask.

Big El,
I think you can ditch the RGB To Color block, if that's what you're using.
If I understand your description, what you need to do is use Interleave 1D Arrays to combine your three sine arrays together into one long array. Then use Draw Flattened Pixmap to turn the array into a picture. You can use Bundle By Name to stick your interleaved array into the image data cluster, and also make sure to specify 24-bit image depth and an appropriate bounding box.
Hope that makes sense,
John
