How to save image of scrollable graph

[pcmanik]

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

I'm saving LineChartView as image into user photo library using

let chartImage = chartView.getChartImage(transparent: false)
UIImageWriteToSavedPhotosAlbum(chartImage, nil, nil, nil)

Content of this chart can't fit into chart view so user is able to scroll it.

What did you expect to happen?

I'm excepting that the resulting image will contain the whole chart. Or at least multiple images.

What happened instead?

Resulting image contains only the visible portion of the chart

Hey @pcmanik you got the solution of this?

@vaibhav-nickelfox I've used one "hack". Before requesting the image i expand the width constraint of the view to the full width of chart. Than I create the image. After it's processed I shrink the width constraint back to original width.

But there were still some issues so in the end I've created my own simple library for plotting ECG graph.
