How to add values in spline chart dynamically

Is there a way to choose the color of the Area Chart? If there isn't a way could you please add a method that lets you customize the charts? (colors etc.)

Labels are not shown when running Semi Circle Pie Chart example. Any way I could get them to work?

how to change size of chart. actually i am changing height and width in xml file, if i set (match parent) its working fine but i want to decrease size of chart so i am giving hard code height and width but its not working.

How to set the color in Step Line Chart

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.suryavanshi.piegraph/com.example.suryavanshi.piegraph.MainActivity}: android.view.InflateException: Binary XML file line #8: Error inflating class com.suryavanshi.graphlibrary.PieGraph

The problem comes because the columns list is null initially and it is being called in the view.
I think this issue could be solved by simply initialising rows, columns and data fields with 0 size arraylists.

BarData data = new BarData(labels, datasets);

Constructor cannot be resolved is showing. What is the possible solution for the same. In Old version 2.1.6 this issue not coming.

Hi,

I am using WaterFallChart class to plot a chart. When I passed 2 or more consecutive negative values in data It starts plotting red color bar from top edge of previous red bar. If I pass alternate values(positive and negative) it plots properly.

Need your help to fix this issue.
Thanking you.

I want to set label width to each section of funnel chart and show fix custom color to each section. Now in getting different colors for each section every time when i run the app. i am using lib version
compile 'com.numetriclabz.numandroidcharts:numandroidcharts:1.0.20'
code:
funnelChart = (FunnelChart) findViewById(R.id.pyramid);
List values = new ArrayList<>();

    values.add(new ChartData("visits", 400));
    values.add(new ChartData("unique visits", 2000));
    values.add(new ChartData("unique visitors", 1000));
    values.add(new ChartData("unique session", 500));
    values.add(new ChartData("log out", 3000));
    values.add(new ChartData("log out1", 3000));
    values.add(new ChartData("log out2", 100));
    values.add(new ChartData("log out3", 1500));
    values.add(new ChartData("log", 2500));
    values.add(new ChartData("log o", 2000));

    funnelChart.setData(values);

Thank you!

Hi, thanks for the lib - great work!

I am not able to see the labels for funnel chart:

values.add(new ChartData("visits", 3000));
values.add(new ChartData("unique visits", 2000));
values.add(new ChartData("unique visitors", 1000));
values.add(new ChartData("unique session", 500));
values.add(new ChartData("log out", 400));

I am using the above code to render it. Exactly like it is done in the tutorial. However as the other factors seem to work, the labels are not to be seen.

Please provide multi level pie chart example. need it
Thanks in advance
