<h2>Graphic slider tool: Dynamic range and implicit functions.</h2>
|
|
|
|
<p>You can make x range (not ticks of x axis) of functions to depend on
|
|
parameter value. This can be useful when function domain depends
|
|
on parameter.</p>
|
|
<p>Also implicit functons like circle can be plotted as 2 separate
|
|
functions of same color.</p>
