Line Chart

roshani

Hi !

I saw many library available for line chart.

I also want zoom in & zoom out function in line chart.

Any library which provide zoom in & zoom out feature.

Thanks

Didn't you try just to use scale() function to zoom in and out?

As i understand scale() command works with still image, when my graph is running, how can i use scale() command with running graph.

Just use it. Animated things are just a succession of still images in sequence. calling scale() in draw, scales each of those frames resulting in scaling the animated stuff...

void setup() {
  size(300, 300);
}

void draw() {
  background(255);
  //not scaled
  ellipse(width/8, height/8, frameCount%50, frameCount%50);

  //scaled
  scale(4);
  ellipse(width/8, height/8, frameCount%50, frameCount%50);
}

Also you can use get() / image() to zoom. See the magnifier part of the code in this post
