Save current figure without axis, axis label and other border areas.

How to save current figure without axis, axis label and other white margin spaces around the figure. I don't have direct access to the matrix which is being plotted. So I want to use something like this:

saveas(gcf, "xyz.png");

but additional spaces and axis labels are also coming into it. I want these to be removed. I want to save only the actual plot area.

Yes, you do. The axes children will always contain the data that is being plotted. So, the easiest would be to replot the figure with,

axis off
export_graphics(gcf, "xyz.png")

A less graceful alternative would be to use export_fig, downloadable from,

https://github.com/altmany/export_fig

which let's you specify the amount of cropping of the exported image. Choose the cropping just right and you will clip away the axis markings.

The "axis off "option is not useful. Still white spaces are coming around the actual plot on all four sides. Hence not useful.

With which of the two solutions I mentioned? With export_fig, all white space will be removed by default and you have input switches to adjust the amount of cropping if you wish.

The export_fig from github is working fine. Thank you.
