Use action button to create points

Questions
1

Hello,

I’m brand new to CL (I just learned about it this week). I’m trying to create an action button that adds points to the line y=2x when pressed. I’ve been able to get it to plot random points on that line using the following code:

r = randomGenerator(btn1.pressCount)

number(“c”): r.float(-3,3)

And my graph has the following point:

(c, c*2)

However, every time I press the action button, the old point goes away and a new point appears. I would like the old point to stay and a new point appear. In other words, as I press the button more, the line starts to fill out.

Is this possible?

You can capture the history of the random numbers. Add these things to what you already have:

Graph

numberList("C"): btn1.history("C")

Button

capture("C"): graph.number("c")

Then create a new point in the graphing calculator of (C, 2C).

That worked perfectly! Thank you.

I love how much the computation layer allows you to do. But, its also a lot to learn :slight_smile:
