Line chart - LineChartDataSet Background color.

[Kiee79]

Hi ,

I am new with charts so is it maybe easy way to have different background colors for each LineChartDataSet ? @liuxuan30

Yeah, you would just have to set the chart data for the different data sets...

[Kiee79]

No , I mean change grid background for different sets ,no line color etc :)

[dangell7]

self.lineChartView.gridBackgroundColor = UIColor.darkGray

[Kiee79]

Yes but I want to divide grid by sets and set different color for different part of grid :)

[dangell7]

So first set:

var dataSetFirst: Bool = false
var dataSetSecond: Bool = false

Then in your code set your bools:

dataSetFirst = true
dataSetFirst = true

Then when you initialize your graphs use

if dataSetFirst == true {
self.lineChartView.gridBackgroundColor = UIColor.darkGray
} else if dataSetSecond == true {
self.lineChartView.gridBackgroundColor = UIColor.darkGray
}

It won't work when I have 3 sets on 1 chart and I need 3 colors at the same time.

[dangell7]

Wait different "part" of the grid? I dont know if thats possible

[dangell7]

I get it now, sorry...

[Kiee79]

Yes. 1 chart , 3 sets , 3 grid colors at the same time. No problem, thanks for your help anyway :)

[dangell7]

You could remove the grid and change the color of the line maybe?

[dangell7]

But Im not sure you can achieve what you want

[Kiee79]

I guess I need to do sth with method "drawGridBackground" but i
I counted that someone had already done it.

[dangell7]

Hmm, well please post here if you figure it out, I would be interested in checking it out.

if you mean fill beneath the line, enable drawFilledEnabled
if you are asking drawGridBackground, it's in the code.
The library does not have something called data set grid background.
