Update: Gantt Charts In FileMaker

Nearly 3 years ago, Kevin McGee wrote a blog post entitled How to: Gantt Charts in FileMaker. Since then, we’ve had a lot of interest in native Filemaker Gantt charts. Today I would like to show you a sample file with a very simple Gantt chart, and explain some of the basic principles involved.

Download the sample file:
FP7 (Filemaker 11)
FMP12 (Filemaker 12) (Download the unlocked version of the Gantt Chart Solution at the bottom of the page)

Here is what the chart looks like in FileMaker 11:


This example uses no container fields and no external code. The entire chart is displayed using conditional formatting on top of repeating fields.

The chart’s date range is driven by a single global date field. This field (called zv__startDate__gd) seen in a merge field at the top left, determines the starting date of the chart. There is then a repeating global date field (zc__date__rgd) used to get each day in the chart based on that starting date. In this example, I have set the number of repetitions to 40, however this can be changed to any number.

Extend(zv__startDate__gd) + Get(CalculationRepetitionNumber) – 1

The dates displayed at the top of the chart are based on this field. A second repeating field in the Task table is used to determine if the current date of the chart falls within the start and end dates of the Task

Let([current_date = Extend(zv__startDate__gd) + Get ( CalculationRepetitionNumber )];If(current_date > Extend(startDate) and current_date < Extend(endDate) + 2; Extend(colour)))

This field sets the value of each repetition that falls within the date range to the value of the colour field. This simply prints the colour as text inside the repeating field, however once we apply some conditional formatting we can change that to fill the entire cell with the correct colour.

gantt conditional formatting

Lastly, to make the chart look a little cleaner we will need an empty repeating field to sit behind everything else and provide the styling for the background of the report. In this example, we have borders to display vertical lines down the layout denoting each day, we also have conditional formatting to make the weekends grey and the current day yellow.

GetRepetition (Task::zc__date__rgd ;Get ( CalculationRepetitionNumber )) = Get ( CurrentDate )
Let([day_name = DayName(GetRepetition ( Task::zc__date__rgd ;Get ( CalculationRepetitionNumber )))];day_name = “Sunday”orday_name = “Saturday”)

These are the basic principals used in this simple Gantt chart example. If you are looking to make your own Gantt chart, I hope that you will find at least some of this article helpful. If you have any questions or comments feel free to leave them in the section below.

    done all kinds of adaptions; booking email system, online creative and much more, using search to hide expired, show certain ranges, one thing would be great to hide expired months. its been great

    Can't thank you enough for providing the unlocked version for this file. I was looking at Omni Plan and Smartsheet. Both of which were overkill for what I needed not to mention expensive. I am going to try and modify it some to accommodate resources attached to tasks, would like to hear any suggestions you may have to approach this. Thanks

    Is there a way that the gantt chart accepts certain days, like for example only mondays and wednesdays so that the gantt chart only shows colours on those days? I've tried it myself but I'm not that good in Filemaker
