You need to run the entire for loop without drawing to set min and max

Then run the 2nd for loop and set fill accordingly to max and min and draw the rect after setting fill

yes, like

```auto
size(300, 300);
int[]data={50, 100, 30, 120, 40, 70, 150};
int max=-1000, min=1000;

for (int i=0; i<data.length; i++) { // first min max run
  if ( max < data[i]) max = data[i];
  if ( min > data[i]) min = data[i];
}

for (int i=0; i<data.length; i++) { // draw run
  fill(255); // make color 
  if ( max == data[i] ) fill(255, 0, 0);
  if ( min == data[i] ) fill(0, 0, 255);
  rect(10+15*i, 10, 10, data[i]); // draw
}

```
