Line Chart for Tracking Remaining Budget Week Over Week

I’m looking to use the line chart to create a budget burndown report in Kantata that works in the following way.

X Axis

• Weekly timeline based on Project Start Date and Project End Date
• Week = Sunday - Saturday

Y Axis 

• Target burndown trend line based on Project Hours Estimate / number of weeks between Project Start Date and Project End Date
• Trend line beginning with Project Hours Estimate, populating week over week with Hours Remaining
  • Begin with Project Hours Estimate (total available hours)
  • Each week, add a data point based on Remaining Hours

Bonus if this can be combo chart with a weekly column to display hours used each week.
