I need help doing a bar chart from a array of four numbers.

1. I want to do a mouse over each chart and the color changes individually;

      1.1. Theres an if/else on the code, but i think i must create a for loop to do the over on each bar.

      

2. The next phase is when i click on each bar they fix on a color.

What i need to do to make topic 1 and 2.

Thanks

Hello i'm new to processing and i've no programming background.

I'm using processing to make things related to design.

So here is my question:

1. I want to analyse images accessing each pixel;

2. Store de RBG value of each pixel;

3. Calculate the average of each color value;

4. Fill the screen with the average color;

5. In the future i want the 2nd and 3rd most used colors too, but now i'm happy with one color;

I'm very basic with this language.

I've started with the code above and i want to develop it gradually if anyone can help.

Thanks
