Show grid with axis deactivated

[gmoraleda]

I'm working with this great library but I'm facing an issue I cannot solve.
I deactivated my Y and X axis so that the graph goes till the screen margins:

    mainChartView.rightAxis.enabled = false
    mainChartView.leftAxis.enabled = false
    mainChartView.leftAxis.axisMaximum = 1.2
    mainChartView.leftAxis.axisMinimum = 0
    mainChartView.xAxis.enabled = false

Nevertheless I want to draw a background grid. Is that possible?

This is my current graph:

And this is how I would like it to be:

Thanks in advance!

grid background is not supported yet. We are planning but it should be a long time.
Either you change the source code and maybe a PR for us, or just wait.
