C) Synchronizing the axes

A)Building a Waterfall chart with guiding lines

B)Creating a Lollipop Chart

ABuilding a waterfall chart with guiding lines

Building a waterfall chart with guiding lines1. Create the data foundation

8

Designing a simple waterfall chart is easy

- Create a bar chart with one expression per bar

- Add offset for each bar to match the “end” of the preceding bar

But: Lines can only be drawn across values of a chart dimension

- You cannot draw a line from one expression to another

So: Reflect your waterfall structure in the data so you can use it as a dimension

- The best option is to adjust your data model accordingly (or add a mapping table)

- If you cannot change the data model, it can also be done using a synthetic dimension (avoid this if possible)Pick(ValueLoop(1,12), ‘Revenue’, ‘Cost of revenue’, […])

Building a waterfall chart with guiding lines2. Create the waterfall

Create a combo chart, adding a bar expression for your P&L figures

Add the offset to the barsI used chart inter-record functions referencing my main expression Amount

Building a waterfall chart with guiding lines3. Add the lines

10

Add a line expression for your first connecting lineOnce again, I used chart inter-record functions referencing the main expression Amount

Cut off the line by setting it to null outside the desired area (e.g. via dimension index)

Repeat for each of the connecting lines

BCreating a lollipop chart

Creating a lollipop chart1. Create the sticks and dots

13

Create the sticks (= upper whiskers of a box plot)All other box plot expressions are set to 0

Add the dots to complete the lollipops and color them

Creating a lollipop chart2. Add the numbers

14

Adding the values to the dots just won’t cut it

Values are always on the right

→ Add an expression with bars instead

→ Make the bars transparent

(e.g. ARGB(0,0,0,0) )

15

CSynchronizing axes

Synchronizing axesBackground

16

For a correct display, the scaling of all bars have to be the same

→ How to achieve this?

Synchronizing axes1. Harmonize the axis scales

17

In a variable, calculate the maximum axis extent across all chartsUsually, this would involve an “Aggr” expression over your P&L position dimension. This is an example for the positive maximum of the axis:

Apply the formula to the axis limits of all your chartsIf you know you’ll only have positive income, this step becomes easier :-)

Synchronizing axes2. Adjust chart sizes

18

Fix the layout of your chart by resizing the chart areaCtrl-shift will make the boundaries appear

Resize the charts manually so they show the same bar length for the same value

Synchronizing axesConclusion

Excerpt from QlikDevGroup’s Mission Statement

For my X-mas wish list

Qlik, please make axis synchronization across charts more convenient!

Final Remarks

This small project is another example of how QlikView can be tuned (and hacked) to match virtually any business requirement. And while this can be a cool challenge for us Qlik addicts, it also bears the temptation to cross the line to solutions that are hard to maintain. It is difficult to say no to something you know is technically possible, but it’s a good idea to learn how to do so.
