How can I add scrollbar to the subplots?
I have gone through many tutorials but they seem quite difficult to understand (ex: Scrolling Figure Demo)
Any easier method to implement?
My code looks like the following. It creates two figures ,one for multiple plots and one for subplots. For the case of subplots i wanted to have scroll bar so as i can slide it down.
I dont know how to call this function, if i replace the call of addaxis to my function then how would the axis be readjusted without any call to addaxis function.

I’m not sure what demo you are referring to, but let me explain how I would implement such a functionality.
The idea is to create a large panel inside a figure, which will contain all the subplots. The panel would be larger than the figure in size. You will have to manually position the axes inside this panel. Also using a slider, you will have to maintain the position of the panel itself to control which part of it is visible.
Consider the following example. We will create a figure such that we scroll vertically to see all the subplots.
We start by creating a figure, and placing a panel and a slider components to fill the entire figure:
For now the slider is disabled. Note that in order to keep things simple, I turned off figure resizing. That way we can position components in fixed pixel units.
Next, we will create new axes one at a time, making each fill one view page. I placed that code inside a separate function
addAxisfor easy use. First let me show how we call this function:The
addAxissimply grows the container panel in size, creates an axis, position it on the top, adjusts the slider limits, then returns a handle to the newly created axis.The slider callback function simply shifts the panel up and down according to the current value of the slider:
The result of this example:
