Method Detail
addPoint(newpoint)
Adds a point to the array of points to be interpolated.
It also checks if the point is outside the current viewing window and
adjusts if necessary.
- Parameters:
- {Point} newpoint
- The newpoint to be drawn
changeInterpolation(value)
- Parameters:
- value
changeX(rangestring)
Read and parse input of x-range and updates the x-range.
- Parameters:
- {string} rangestring
- The values for xhigh and xlow as a string
changeY(rangestring)
Read and parse input of y-range and updates the y-range.
- Parameters:
- {string} rangestring
- The values for yhigh and ylow as a string
clear()
Clears all points and functions from the graph
drawAxes()
Draws the axes of the graph along with the gridlines within
drawFunction(interpolated)
Draws a function on the graph by drawing lines between calculated points.
- Parameters:
- {Polynomial|Term} interpolated
- The interpolated function
drawLatest()
Draw the latest function added
drawPoints()
Draws all points currently in array onto graph
<inner>
lsq(points)
- Parameters:
- points
plotAndConnectPoints(points)
Draws a curve defined by points
- Parameters:
- {Point[]} points
- The points to be plotted and connected;
