fill one color in google chart

We are trying to fill only one color in google area chart, with different line color.

If we use

isStacked:true

then it will change chart representation
(change y-axis max coordinate)

we want to fill only one color
(green color below the max border in chart).

You mean like this: https://jsfiddle.net/7uyz541m/1/ or this: https://jsfiddle.net/7uyz541m/2/ ?

You can set the areaOpacity to zero to remove the filling of a series. The difference between the first and second jsfiddle link is the isstacked value.

series: {
          0: {
              areaOpacity: 0
          }
        },

To make both areas the "same" color but the line a different color you need to add a dummy column like here: https://jsfiddle.net/7uyz541m/3

Using a ComboChart and two sets of the same data, I believe I was able to achieve the desired result.

Note definitions for each series
The first two are identical using areaOpacity: 1 to prevent color mix
These are also not visibleInLegend

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);


function drawChart() {
  var data1 = google.visualization.arrayToDataTable([
    ['Year', 'Sales', 'Expenses', 'Expenses', 'Sales'],
    ['2013',  1000,    400,        400,        1000  ],
