philackm / scrollablegraphview Goto Github PK

I just wanted to say thank you to the developer behind this. This has been the best graph option I have ever come across. It's easy to implement, very attractive, easy for the user to interact with, and highly customizable. I also appreciate that the whole thing is in a single Swift file I can just drop in my project.

Thanks for all your hard work! This is fantastic! :)

dataPointLabelsSparsity is shown in the documentation as an available property yet is not implemented in the actual library. Would be nice to have it available as it sounds super useful.

Hi,
For iOS and macOS projets it's will be great to make your component Carthage compatible

Take a look at these articles:

• Ruthlessly Simple Dependency Management with Carthage
• Carthage Tutorial: Getting Started
• Making Carthage-compatible Frameworks with Swift
• Swift Cross Platform Framework (section Configure targets for Carthage) 👍

On your README.md add on top and add section for the installation with Carthage.

I want "dataPointSpacing" to calculate automatically based on the graph area width (No Scrolling). Is there is any way to achieve that with the current API's?

Multiple language features will be removed in Swift 3. The deprecated language features must be replaced with the Swift 3 equivalents.

I have a graph that shows data from 1 to 5 and i have labels that equal the date the data was submitted. On the left hand side it shows the data numbers but I want to make them strings where 1 = Good Day, 2 = Ok Day, ect. Is that possible?

i am using scrollable-graphview... so I think that is very beautiful chart
but i have to show data value... but scrollable graphview only show path...
how can i show data value each bar ... or each line datapoint ?

It would be really nice to be able to not only create the object in interface builder but to be able to design the object in interface builder as well.

To fix the first problem you need to replace the initWithCoder function with

required public init?(coder aDecoder: NSCoder) {`
    super.init(coder: aDecoder)`
}

Secondly, after // MARK: - ScrollableGraphView you need to mark the class as "designable" by adding @IBDesignable. Then for each variable which you wish to expose to interface builder you need to mark the variable with @IBInspectable. For example:

public var lineWidth: CGFloat = 2
// Will become
@IBInspectable public var lineWidth: CGFloat = 2

Finally you need to implement this function:

public override func prepareForInterfaceBuilder() {
    //Setup view
}

Hi all !

is it possible to display the bar layer horizontally and not vertically ?

Thanks !

is it possible to show multiple line in the graph?

I have my Graph already displayed. If I tap on a button, i'd like to change the strokecolor of the lineLayer. So I added this in the class:

public func changeLineColor(color : UIColor) {    
  lineLayer?.strokeColor = color.CGColor
}

But if I call it from my view like: myGraph.changeLineColor(myColor) , it will return the error:

fatal error: use of unimplemented initializer 'init(layer:)' for class 'TestGraph.ScrollableGraphViewDrawingLayer'

I can still change the background color by adding this function and it works:

public func changeBackgroundColor(color : UIColor) {
drawingView.backgroundColor = color
}

BUT do you have any idea why I can't change the linecolor ? :/ thanks !!

How to detect the tap gesture on the label on the x-axis?

Goal is when the graph is displayed, no "circle" on the curve is displayed but if you tap on the label, the corresponding circle will be displayed with the corresponding value somewhere

I'm having some trouble wondering how to refactor my projects in a way that fits the modifications made by Swift 3 conversion.

is it possible to reduce the number labels shown on the x-axis? When I have to show large number of points , label in the x-axis are overlapping. And I don't want large spacing between those points.

It should be possible to add tvOS support. You should just have to disable any touch based apis by wrapping them in checking for the tvOS target.

Is there a way to scroll to the end of the view after the animation is complete? or even before the animation starts?

Is there a way to format the label on y axis? Would be great to be able to format the string. It's useful to display currency and other types of data.

(or stop the line from rendering after the last data point)

Scenario:
With rightmostPointPadding = 0 my last label gets cut off:

If I extend the padding (or the user pulls to the left more) the line drops down to 0 and looks a little odd

Is it possible to do any of these options?

1. The line continues on whatever it's current trajectory is on
2. Stop it rendering at the last data point (the vertical line being ok, the horizontal one not)
   
3. Prevent the user from swiping past the last data point (not ideal because then the last label gets cut in half)

Thanks!

thank you for your project. i want to change a point color. not all point but a special point. for example, i want change points which are above 30 to red and 30 less than are be white.
how and where can i do it??

I'd be cool to also add Cocoapods support. I done this implementation myself last month for my library. Just follow this post and this checklist.

Using autolayout, I set the graphview 8px trailing and leading space to its view container. However the graph line is overflow. Please take a look at the picture: https://gyazo.com/4d0bfee262e9977983c568b8943c6d17

Hi,

For first, thanks for this awesome code.

At this time I am facing a problem with labels and my question is if there is a way to add a value on top of the bar, for example I have a bar of month January and at the bottom I want to add "January" label and on top of this bar I want to add "R$ 100,00" as a String, is this possible? If yes, please someone can explain how?

PS: Please label it as Question ;)

Thanks.

I want to show more than one lines in the graph. Is it possible to show add two or more lines in the same graph? Please provide a solution.

Hi Guys

I was wondering how to add shadow to the main line that is connecting the dots as I was inspired by a design. I have figure it out. I'm kindly asking the author of the library to expose it, so can be added easily.

the final goal is to get line which will have shadow as the example below created by Sam Thibault in one of his prototypes.

Because this line chart is using CALayer it can have shadow very easy. You just need to find it where exactly is and add the code.

In file ScrollableraphView.swift locate the function shown bellow i.e. "addDrawingLayers" and add the code to add your shadow(of course you can change the values to change the type of the shadow):
bear in mind that I have switched off the property graphView.shouldFill = false because I wanted the shadow to be below the line.

        lineLayer?.shadowOffset = CGSize(width: 4,height: 4)
        lineLayer?.shadowColor = UIColor.darkGrayColor().CGColor
        lineLayer?.shadowRadius = 2.0
        lineLayer?.shadowOpacity = 1.0

After adding the code the line chart was like this

And this is how looks like the function after i added the code.

If someone have idea how to create the gradient for the line itself, it would be great.

Cheers.

You have shown in Demo that we can also use it as bar chart . but there are no methods avaliable for bar chart

Hello, I'm using Scrollable-GraphView of DarkGraph. But I don't know to add the x-axis and y-axis values from my end I have dates in x-axis and float values in Y-axis in different arrays.
How can I give the 2 arrays to X-axis and Y-axis. Thanks!

It would be great to have the option to display the dataPointsLabels (x-axis) under the graph, so it's not in the filled area.

Hi.
Your framework be very helpful. I have a issues need your support with set color barColor as photo bellow. You can help me?.

It would be nice to have the posibility to set indivudual colors for each point or bar, and also to group multiple data values for each label

Hi, I'm trying to use your Lib, but when I add " pod 'ScrollableGraphView' " to my Podfile, the following error occurs.. " Unable to find a specification for 'ScrollableGraphView' ". How can I solve this problem?

Consider this a feature request rather than a bug. :)

It would be much more convenient to be able to connect directly to the GraphView from Interface Builder. Unfortunately, I have to create a container right now, because when I hook it up in IB, it tries to call the method that is not implemented yet:

required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") }

: Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.

This line of code is crashing the app.
assert (layer.zeroYPosition > 0);

I tried setting the delegate but touchesBegan or other touch events don't fire from the ScrollableGraphView - they fire from my normal view just fine.

I am asking this question so we can add dynamically more data the more the users scrolls.

Hi guys,

Do you have any idea how to put GraphView in tableViewCell?
I'm getting lots of crash and can't list two or three different graphs in a tableview

Thanks.

Scroll feature is awesome. While scroll reach at and should be option of append new data and add new point in graph.

Hi,

Nice work indeed.
Can we have 2 line scrollable graph?
This will be a nice enhancement!

Thank you very much

George Gerardis

We’d love to use this library in our Mac app—it looks fantastic!

Hi,

Could you please add an option to plot multiple values on the graph and an option to select a node/value?

Thanks. Love the Graph.

Hello!

First of all I want to thank you about this awesome library! I'm using it in a new project and It's really smooth. I only have one question. Is it posible to automatically scroll to the end of the graph after it appears on the view?

Best regards!

Hi,

First of all thanks for this awesome library!

I've been using it and sometimes the graph gets updated twice (usually with the same data), before the animation of the first calls finishes. And this causes the animation to abort and restart for the 2nd call. Which looks odd.

To test this include the following code in the viewDidLoad method of the example project:

  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(graphView.animationDuration * 0.5 * Double(NSEC_PER_SEC))), dispatch_get_main_queue()){
       self.graphView.setData(self.data, withLabels: self.labels)
 }

I think possible solutions would be:

1. Always start the 2nd animation at the current point each point is
2. If the 2nd call has the exact same data as the currently animating call, don't animate it.

Can you please update it to support Swift 3?

First of all, great library, I really like it :)

I'm wondering if we could add more flexiblity to shouldAutomaticallyDetectRange = true. Right now, it will resize the graph depending on what is the max-y value and min-y value. I m wondering if we can add some vertical margin in there?

Example: if max-y value is 115, and y-margin is 15, then highest value in graph would be 130 and not 115 like it is now.

I know that I can just find out what is my max y value and then compute the new rangeMax and rangeMin, but I think it would be nice to have it in the library. I can also help with that if need be, it should not be hard by looking at the code :)

Hi,
first of all thank you very much for this great framework!

But currently it is not possible to draw negative bars below zero. E.g. try to draw data = [-10.0, 10.0] with minRange = -20.0: Both bars will start to draw from -20 instead of the baseline 0.

I wanna keep just the horizontal scrolling and disable vertical. How do I do this?

This is the default behavior

I want the graph t position itself like this.

Or even disable the vertical scroll. Please help me.

It would be really nice to have some /// comments before each variable so we know what each one is doing without having to reverse engineer your code 😄

Hi people, I wonder , how to put the lines on the x axis.
