mpandroidchart I want to get 3rd value

问题

I am using mpandroidchart and i have a problem now

I set 3 values into the array likes this (index, values, and another value)

ArrayList<Entry> value1 = new ArrayList<>();

    for (int i = 0; i < 10; i++) {  
        float y = (float) Math.random();
        float h = (float) Math.random();
        value1.add(new Entry(i, y, h));
        }

I want to get h values to use this h

but i cant' find the way

How can i get h value?

Thanks for reading

* Edited2 *

ArrayList<Integer> color;
        ArrayList<Entry> value1 = new ArrayList<>();
        for (int i = 0; i < 10; i++) {  
            float y = (float) Math.random();
            value1.add(new Entry(i, y));
            if(y>10)
            {
                color.add(context.getResources().getColor(R.color.colorPrimary));
            }
            else
                color.add(context.getResources().getColor(R.color.colorAccent));
        }
        dataSet.setColors(color);

Dear M.Saad Lakhan You suggested like upper code, But there are some ploblems.

ArrayList color; -> "variable 'color' might not have been initiallized
color.add(context.getResources().getColor(R.color.colorPrimary) -> cannot resolve symbol 'context'
ArrayList dataSets = new ArrayList<>(); //this is my code dataSets.setColors(color); -> there is no setColors in my datasets

What are these problem?

回答1:

You need to create:

ArrayList<Integer> colors = new ArrayList<>();

After that you need to add values for each entry which color you want to show, you need to modify your code as:

ArrayList<Entry> value1 = new ArrayList<>();

for (int i = 0; i < 10; i++) 
{  
   float y = (float) Math.random();
   value1.add(new Entry(i, y));
// add your condition here
if(y>10)
 {
   color.add(getContext().getResources().getColor(R.color.colorPrimary));
 }
else
   color.add(getContext().getResources().getColor(R.color.colorAccent));
}

When you complete your colors arraylist then you can set colors as:

dataSet.setColors(color);
