Create an image of the entire chart

[sbeff]

Hello everyone, I need to create an image of the entire chart like this:

If I use the getChartImage function, I only get an image of the chart that is currently displayed on the screen, like this one:

Thanks in advance to everyone!

I'm confused. You already got what is rendered. For those not showing up, use renderInContext
You should search SO instead...:https://stackoverflow.com/questions/4334233/how-to-capture-uiview-to-uiimage-without-loss-of-quality-on-retina-display

I edited that screenshot, it was not taken with getChartImage function.

oh you mean what you shot is not the full data entries?

If you already zoomed and scrolled, NSUIGraphicsGetImageFromCurrentImageContext just takes whatever is on the screen right now

If you want to take the original chart, you have to reset the scale and offset and do it again. Or you manually create another ghost view to use renderInContext render off screen, however this will also take CPU power just like what you rendered on screen, but not showing actually.
