ChartJS Stacked Bar Chart: Showing value in opposite directions

After some research and study, finally I got a way out regarding my problem I have posted here.

public static drawDashboard2Chart(data: Dashboard2Data[], canvas: ElementRef) {
const planProfit = data.map(dataUnit => dataUnit.p_profit);
const planExpenses = data.map(dataUnit => dataUnit.p_expenses);
const planSalary = data.map(dataUnit => dataUnit.p_salary);
const factProfit = data.map(dataUnit => dataUnit.f_profit);
const factExpenses = data.map(dataUnit => dataUnit.f_expenses);
const factSalary = data.map(dataUnit => dataUnit.f_salary);

const ctx = canvas.nativeElement.getContext('2d');

const dataArray = [
  {
    label: 'REVENUES PLAN',
    backgroundColor: '#d14035',
    hoverBackgroundColor: '#d14035',
    stack: '0',
    data: planProfit,
    datalabels: {
      color: '#d14035',
    }
  },
  {
    label: 'SALARY PLAN',

    data: planSalary,

    data: planExpenses,
