Graph mapper- control by slider

Hi I am trying to integrate grasshopper defination on web using rhinocompute and I was wondering if anyone knows how I can alter my grasshopper defination to have sliders THAT CONTROL GRAPH MAPPER (32.7 KB) .

Since HTML has option to input sliders(range), I can easily control them in html and assign to grasshopper defination but not graph mapper (hence need a way to control the graph mapper using sliders)

basically a grasshopper question!

you might recreate a Parabola function with an Evaluate or Expression component, and use its output instead of the graph mapper (41.2 KB)
