‘Bullet charts’ with a dynamic goal in Google Data Studio

Google Data Studio, recently released into worldwide Beta, has a good range of charts and data layout options built in by default.

One of my favourites is the bullet chart. However, one frustration I have found is that you can’t currently set a dynamic value for your goal, and editing the report to update this number isn’t always possible.

In the example below I have shared my process for recreating a bullet/goal chart by overlaying two bar charts, and linking one to a dynamic goal with a new value every day.

How to recreate this chart in Data Studio

My requirement was for a chart which would show a team their daily progress towards a goal – something a bullet chart would be perfect for, but in this case the targets we’re different for every day of the year. I didn’t want to have to edit the report each day to update the goal value, so I created a workout with a chart above.

Looks like something that would be useful for your reports? Great, let’s look at how it works!

This chart is actually two bar charts, one on top of the other, where the one below tracks the goal and the one on the top tracks the actual performance at the time of viewing. In the example above this is for target orders in a day against current orders (connected to Google Analytics and updating throughout the day).

Here’s how they look pulled apart – see how simple it really is:

Step 1: Create 2 bar charts, one for your goal and one for your target metric.

The bar for your goal can be a fixed amount, if your goal is the same every day, but in this example it’s connected to a Google Sheet which contains 2 columns – date and target orders. The value of the grey bar will read the new target from the Google Sheet every day and update the goal accordingly.

Step 2: Fix your axis to the same values

Fixed axis are important, as this will keep your progress in content to your goal – for example if you have an axis of 100 on your progress but 200 on your goal, it’s going to look as through you are twice as close to your goal than you actually are!

Step 2: Style your value axis so that they are visually hidden.

The marks on your axis are going to be different – you can’t currently hide them in Data Studio so I have made mine white, which on a white background makes them invisible.

Step 3: Drag your target bar chart on top of your goal chart and position to your preference.

That’s it, simple!

Things to keep in mind

  • Because your using a fixed axis, if your target figure is pulling from an external source (as in the example above) and this exceeds the maximum axis value, your data will fall off the chart. So set your axis at a comfortable level that will allow your target to grow without you having to edit your report.
  • What happens when you reach your goal? Your goal bar will continue to grow over the top of your target – you can tweak the visuals to make this more obvious, perhaps something like this?
