Moving pie chart location (legend overlaps chart)

[royherma]

Is there a way to control the location of the actual chart within the actual PieChartView? My view spans across the whole view controller's UIView, but is always centered. The rendering rect is private for the PieChartView so I can't access it, any ideas of how I can solve the issue (could involve legend as well). I added a picture for reference.

Thanks!

I just played with the ChartsDemo pie chart, similar case. I guess you have to modify some code and re-build it so you can use.
however, I think this is not a good way, but actually you can choose write your own chart legend, like putting it in a scroll view, or some tricks
@danielgindi I found another bug is, in charts demo, if you drag the slider, the pie chart radius trend is: decreasing --> increasing

Hi royhema

I want to use pieBarChar but there's no documentation on how to use it , and I tried to translate demo project as I don't know Objective-C but a lot of errors are showing , can you just show me how to get and put hard coded values just as an example , so I get an idea on how to work with dynamic numbers . Thanks very much.
And sorry for the off-topic question.

@dushiarlind your question is not clear. you have to understand you just needs to create pie chart data set with your values, and create pie chart data and feed it to pie chart view. Objc is one of the most easiest code to read and understand, you just have to get the idea. take a look at - (void)setDataCount:(int)count range:(double)range in pieChartViewController,

PieChartDataSet *dataSet = [[PieChartDataSet alloc] initWithYVals:yVals1 label:@"Election Results"];
_chartView.data = data;
is how you create it and feed it to chart view.
But do remember, first configure your chart view, and then set the data, not the revsered way.

@liuxuan30 Sorry for not clearing things up.

I've put a uiview in my storyboard , set class to PieChartView and created an IBOutlet .

Now I need this pie to show me 3 slices with different numbers which will come to me from json object.
Let's say I parsed the numbers and stored them in 3 variables. Now I want to put them in the pieChart.
How do I do that .
So I've got myPieChart and variables let slice1 , let slice2 and let slice3 which containt 3 different numbers.

as I said, "you have to understand you just needs to create pie chart data set with your values, and create pie chart data and feed it to pie chart view." You should look at the ChartsDemo first.
Please avoid your further questions on this thread. It's distracting. I do not suggest you open a new one for the same question, as the answer is obvious and already in the code, I merely say what the code say.

@royherma Were you able to figure out moving the location of the PieChart or did you create a custom Scroll view for the legend like @liuxuan30 suggested?

[royherma]

I created a custom scroll view legend from scratch.

If you want complete control, you can now (on master) set the legend to drawInside, to avoid affecting the Pie's position. And then use custom offsets to move the pie around.
