Explicit Function Family y=f(x,a[i]) Plotter (version 2.2)
Restart/Reload This Web PageA more detailed usage of this function plotter is at the end of this page.
- Click "Run/Re-Run Plotter" button to plot the pre-defined example function family.
- To plot your own function family, input your function formula or change the example function.
- Change the default parameters a[i]=a0,a1,a2,,, or input your own parameters, if needed.
- Change or set the plot range [xmin, xmax] for your new function family, if needed.
- Click "Run/Re-Run Plotter" button to plot the new/re-defined function.
Push "Run Plotter" Button to Start
Input Your Function Formula f(x,a) or Change the Pre-defined Example:
Input Parameter a[i]=(a0,a1,a2,a3,,,,). Graph Color Spectrum from Blue to Red:
Input X Plot Range---xmin and xmax:

More Usage Information for the Function Plotter:
- The plotter provides more example functions to demo the function formula syntax, click the "Select Menu,,,"
- For each input parameter a[i], one graph will be added and plotted. The graphs are colored with a spectrum from blue to red.
- The plotter function formula follows JavaScript syntax and support all the JavaScript Math functions,
such as cos(), sin(), abs(), sqrt(), etc.. See "Supported Operators and Functions". - For function formula, supported operators limited to: +(Addition), -(Subtraction), *(Multiplication), /(Division), and ^(or **)(Exponentiation). Other operators, such as &, &&, |, ||, >>, >, <<, <, %, !, etc., are not supported for function formula and they will be treated as errors, although they are legal JavaScript operators.
- Use mouse(left key, down-move-up) to select part of function graph to zoom-in. Use "Zoom-out/Back" button to reverse the zoom-in.
- When move the mouse cursor on the graph, the mouse position (x,y) will be displayed.
- The plotter will catch most of user-input errors and function singularity errors, and will display a notice for possible error correction.
- After correct the error, click "Run/Re-Run Plotter" button to re-run the plotter.
- In current version plotter, data sampling period dx=(xmax-xmin)/1000. For a high frequency function, set a smaller plot range [xmin,xmax] can reduce the dx.
