Scroll after create Graph about scrollablegraphview HOT 11 CLOSED

Just figured it out. You can change the scroll direction:

graphView.direction = ScrollableGraphViewDirection.RightToLeft

RightToLeft will automatically scroll to the end of the graph .

Same problem here.

Hi hdoria!

I tried this line of code but It doesn't work for me 😟

`let graphView = ScrollableGraphView(frame: CGRectMake(0.0, 0.0, self.frame.width, self.frame.height))
graphView.topMargin = 80

    graphView.backgroundFillColor = UIColor.colorFromHex("#333333")

    graphView.lineWidth = 1
    graphView.lineColor = UIColor.colorFromHex("#777777")
    graphView.lineStyle = ScrollableGraphViewLineStyle.Smooth

    graphView.shouldFill = true
    graphView.fillType = ScrollableGraphViewFillType.Gradient
    graphView.fillColor = UIColor.colorFromHex("#555555")
    graphView.fillGradientType = ScrollableGraphViewGradientType.Linear
    graphView.fillGradientStartColor = UIColor.colorFromHex("#555555")
    graphView.fillGradientEndColor = UIColor.colorFromHex("#444444")

    graphView.dataPointSpacing = 80
    graphView.dataPointSize = 2
    graphView.dataPointFillColor = UIColor.whiteColor()

    graphView.referenceLineLabelFont = UIFont.boldSystemFontOfSize(8)
    graphView.referenceLineColor = UIColor.whiteColor().colorWithAlphaComponent(0.2)
    graphView.referenceLineLabelColor = UIColor.whiteColor()
    graphView.dataPointLabelColor = UIColor.whiteColor().colorWithAlphaComponent(0.5)

    graphView.shouldAnimateOnStartup = true
    graphView.shouldAdaptRange = true
    graphView.adaptAnimationType = .Elastic
    graphView.animationDuration = 1.5
    graphView.shouldRangeAlwaysStartAtZero = true

    self.graphView?.direction = .RightToLeft

    graphView.setData(values, withLabels: labels)
    self.graphContainerView.addSubview(graphView)`

from scrollablegraphview.

@hdoria Yes! That property can be used to change which end of the graph it starts at.

@llKoull Try changing:

self.graphView?.direction = .RightToLeft

to

self.graphView.direction = .RightToLeft

I don't think you have declared graphView as an optional.

Otherwise I can't see any other major mistakes. Does it not start at the end of the graph even after changing the direction to .RightToLeft? (Note there is no scrolling animation for this property, it will just start at the end of the graph and the user will have to swipe to the left to see the start of the graph.)

Hi @philackm !

I tried to use self.graphView.direction = .RightToLeft but xcode gives me an error and I cant compile. I also tried to declare it as ! and the i can compile but i get

unexpectedly found nil while unwrapping an Optional value

I always have to scroll from left to right no matters which direction i choose :O

Thanks for your help

I finally got this working, It was my fault, I was using self.grapView and i should use graphview instead.

But now i've got another problem, The graph is scrolling, that's nice! ^_^ but the graphic it's not filled with color It seems that only half part of the graphic is filled until i touch It (some lines and the Y-axis values are also hidden. If i touch the graph It fills up with the correct color).

I attach some pictures!

Thanks and best regards!

Hmmm. Could you post the code you have to a GitHub gist (https://gist.github.com) and then post the link here? I'd like to try reproduce it and find what's causing the bug.

I'm sorry, but i can't post all the code. Anyways, I can tell you what i've done.

I created a UICollectionView with a custom cell called GraphCollectionViewCell. This is the code of the custom cell:

`import UIKit
import ScrollableGraphView

class GraphCollectionViewCell: UICollectionViewCell {

@IBOutlet weak var graphTitle: UILabel!
@IBOutlet weak var graphContainerView: UIView!
var graphView: ScrollableGraphView?

required init(coder aDecoder: NSCoder)
{
    super.init(coder: aDecoder)!
}

func initializeGraph(values: [Double], labels: [String])
{
    let graphView = ScrollableGraphView(frame: CGRectMake(0.0, 0.0, self.frame.width, self.frame.height))
    graphView.topMargin = 80

    graphView.backgroundFillColor = UIColor.colorFromHex("#333333")

    graphView.lineWidth = 1
    graphView.lineColor = UIColor.colorFromHex("#777777")
    graphView.lineStyle = ScrollableGraphViewLineStyle.Smooth

    graphView.shouldFill = true
    graphView.fillType = ScrollableGraphViewFillType.Gradient
    graphView.fillColor = UIColor.colorFromHex("#555555")
    graphView.fillGradientType = ScrollableGraphViewGradientType.Linear
    graphView.fillGradientStartColor = UIColor.colorFromHex("#555555")
    graphView.fillGradientEndColor = UIColor.colorFromHex("#444444")

    graphView.dataPointSpacing = 80
    graphView.dataPointSize = 2
    graphView.dataPointFillColor = UIColor.whiteColor()

    graphView.referenceLineLabelFont = UIFont.boldSystemFontOfSize(8)
    graphView.referenceLineColor = UIColor.whiteColor().colorWithAlphaComponent(0.2)
    graphView.referenceLineLabelColor = UIColor.whiteColor()
    graphView.dataPointLabelColor = UIColor.whiteColor().colorWithAlphaComponent(0.5)

    graphView.shouldAnimateOnStartup = true
    graphView.shouldAdaptRange = true
    graphView.adaptAnimationType = .Elastic
    graphView.animationDuration = 1.5
    graphView.shouldRangeAlwaysStartAtZero = true

    graphView.setData(values, withLabels: labels)
    graphView.direction = .RightToLeft
    self.graphContainerView.addSubview(graphView)
}

// MARK: Setters



// MARK: Getters

}
`

Then I initialize the cell in the main view using the function

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell

with the following code:

let cell = collectionView.dequeueReusableCellWithReuseIdentifier(identifier, forIndexPath: indexPath) as! GraphCollectionViewCell cell.initializeGraph(stepsArray, labels: labelsArray) return cell

I think that I autolayout can be affecting to the view.

Thanks for your help!

Same problem here. This only happens when using ScrollableGraphViewDirection.RightToLeft.

Okay I just pushed 1.1.1 to cocoapods.

@hdoria, @llKoull Can you please try that version and let me know if it is any better?

from scrollablegraphview.

Yeah! It's working perfect! ^_^

Thanks @philackm !!!
