Plotting a bar chart

In this section:

• Introduction
• Simfit plotting styles
• Plotting a pie chart
• Plotting a bar chart
• Plotting y = f(x)
• Plotting r = r(θ)
• Plotting x = x(t), y = y(t)
• Plotting x = x(t), y = y(t), z = z(t)
• Plotting z = f(x,y)

The following code is extracted from program simdem48.f95 in the Simdem package, and it illustrates how easy it is to plot a matrix, declared as double precision x(nmax,ncol), as a bar chart.

!
! initialise essential arguments for default bar chart
!
      do j = 1, ncol
         do i = 1, nrow
            x(i,j) = dble(i + j)
         enddo
      enddo
      titles(1) = 'Demonstrating a Simfit bar chart'
      titles(2) = 'Rows'
      titles(3) = 'Columns'
      titles(4) = blank
!
! isend = 1: call bcplot in default mode
!
      isend = 1
      call bcplot (isend, ncol, nrmax, nrow, x, labels, titles)

The following plot is then displayed and can be edited to add further features, printed, or archived as a graphics file. It is possible to edit the bar labels, keys, and titles, and to perform additional operations like 3D perspective, and side panel re-positioning.
