Demo

Installation

CocoaPods is the recommended way to add Dr-Charts to your project.

Using CocoaPod

Simply add the following line to your Podfile and install the pod.

pod 'drCharts', :git => 'https://github.com/Zomato/DR-charts.git'

Where "dr-charts" is the name of the library.

The Old School Way

The simplest way to add Dr-Charts to your project is to drag and drop the /Classes folder into your Xcode project. It is also recommended to rename the /Classes folder to something more descriptive (i.e. 'Dr-Charts').

drawing the first chart is fine. However, when a second chart is to be drawn, the first graph still is shown thus the second graph overlaps the first one. For any subsequent graph draw attempt causes the overlap to build on top of previous graphs. Similar issue is reported in closed issue #18 Reset Graph. The proposed fix to use ReloadPieChart method does not fix the issue.

Sample Code ; #pragma Mark CreatePieChart

(void)createPieChart{

//PieChart *chart = [[PieChart alloc] initWithFrame:CGRectMake(0, header_height, WIDTH(self.view), (HEIGHT(self.view) - header_height)/2)]; PieChart *chart = [[PieChart alloc] initWithFrame:CGRectMake(0, header_height, 350, 290)]; [chart setDataSource:self]; [chart setDelegate:self]; [chart setShowLegend:TRUE]; //[chart setLegendViewType:LegendTypeHorizontal]; [chart setLegendViewType:LegendTypeVertical]; [chart setTextFontSize:12]; [chart setTextColor:[UIColor redColor]]; [chart setTextFont:[UIFont systemFontOfSize:chart.textFontSize]]; [chart setShowValueOnPieSlice:TRUE]; [chart setShowCustomMarkerView:TRUE]; //[chart drawPieChart]; [chart reloadPieChart]; [self.view addSubview:chart]; }

Bar Chart Overlapping issue

Dear @dhirenthirani

For Bar Graph, I'm returning the number of Bar to be plotted as 3, the 2nd and 3rd bar line is overlapping with each other. To test, Pls return "3" bars for numberOfBarsToBePlotted datasource method. Please let me know any changes to be made in the library.

Best, Imad

Reset graph

Hello!

It might be a silly question, but is there a way to reset/clear the graph previosly drawn? I'm working on the same view and drawing different graphs when a button get clicked.

That's how it looks after I try to redraw it: I tried to reset the view in some ways, but without any luck.

If there isn't the possibility to reset the chart I suggest to insert it, cause it might be useful.

Thanks

[question] Is it possible to make a logarithmic axis

Dear author, thanks for a great work. I need to implement the following chart and I wonder if it's feasible with your library.

I have not found any examples or discussions of logarithmic axis while searching with google and StackOverflow, so I'm asking here.

Thanks in advance.

Rotate x axis labels

Hey. I'm wondering if there is a way to rotate the x axis labels? I can see when creating the ChartAxisValueDouble objects, the default label settings are applied (0 for rotation) and that these objects are then used to build the ChartBarModel objects. However I cannot find a way to edit the label settings for those objects, as the init only access tuples with String and Double.

Pie chart related issue

Previously, in pie chart we have data sources like func numberOfValues(forPieChart pie: UIView!) -> Int {}, So we can use these methods for multiple charts views on the same controller.

But now the library has removed this and now the function is like func numberOfValuesForPieChart() -> Int {}

How can we distinguish between different chart views.

bar chart issue

Hi, in bar chart the x values are overlapping if the text is bigger , if I increase bar width it works fine but when I scroll horizontally the Y values are also scrolled , it is difficult to know bar values on scrolling how Can I fix it. Even If I can show the bar values above all bars without user interaction means that will be much better can you tell me the solution
