I managed to get two columns side by side with the actual data. Here I use SAQL statements to load the data and transform it into two sets (targeted revenue and actual revenue) then union both sets while setting the null values to 0, lastly order them by year and sum of values of both sets side by side. Additional steps require use of 'stacked column' charts while keeping year on the horizontal axis, sums in vertical axis and stacking the values by status (high, medium, low) and setting the axis mode to 'single'. Final data table looks like this.
