Scrolling viz chart on mobile not possible

Hi,

I have the problem, that I can't scroll my plot area for my viz chart on mobile. It works with the examples provided in the Explored section, but not with my chart.

Here is my chart, there appears no scrollbar below the x-axis, all data points are shown at once.

here is an example of the explored section. Because I made the screenshot, the scrollbar below the x-axis vanished, but it is there. Also, as you can see it shows only a part of the chart, not all data points.

So, has anyone an idea, what properties need to be set, or what I need to do to make the plot area of the chart scrollable?

Also, why is the framework not showing the Zoom In and Zoom Out buttons on mobile, only on desktop? That would help me to work around the problem too.

Here the desktop view of the Explored application above, you can see the magnifying glasses here, but not in mobile.

There is a property for that, but it only works with desktop mode and is true initially.

Edit

I forgot to mention that I referred to the application when debugging it in Chrome. I uploaded it to the server now and testing it on my iPhone works. I'm able to scroll and pinch to zoom in and out.

Nevertheless is it possible to make these actions more accessible? Initially it zooms very close into the plot area, only showing two bars, is it possible to set an amount of data points that are shown after start? Is it possible to show the mangnifying lenses anyway, to make the feature more prominent?

And any idea why it behaves differently in Chrome?
