I’m using CanvasJS since few weeks and I have a question about zoom.
I saw we can zoom easily by drag & drop but I would like to create a button to zoom (by click).
Example: I have a button “x2” and when i click on it it zooms x2 on my graph (no drag & drop, just a click).
I searched a lot and i found nothing.
Thank you in advance !
(Sorry my english isn’t perfect !)
To zoom into certain region, you need to change viewportMinimum and viewportMaximum. If you like to set viewportMinimum and viewportMaximum to certain region after clicking the button, you can achieve as shown in this jsfiddle.
Also take a look at this jsfiddle, where viewportMinimum and viewportMaximum are changed based on dropdown options.
