Management accounting analyzes, plans and informs. This requires a reliable database, but also flexibility in designing reports, presentations and dashboards. These requirements often can´t be combined in a software system. The discussion about the authorization of local reporting solutions, that complement central standard systems, is currently up-to-date. The article reports from practice and conveys the advantages and disadvantages of local solutions.

Central versus local reports

When I wrote ‘local report solutions’, I could already hear the prompt “think big or go home”. It seems that the management accounting is focusing on big data and the big BI solution. But what is the true situation? What experiences we make in our projects?

The utopia of the one system into which all the data flows and from which rapidly different reports can be generated to steer the entire enterprise, is the driving force of many positive, important developments. But the resource expenditure behind this idea ist enormous. This type of reporting is made practical by a high degree of standardization and continuity. Data collection and storage benefits from the general conditions.

However, the reports and presentations that provide centralized systems are limited by these conditions. They are not very variable and can only help partially in answering non-standardized questions.

Automated, local reporting tools can overcome these communication hurdles.

Therefore they are a flexible and cost-effective alternative. From our projects we know that a mix of central and local reporting solutions is the best course of action.

The local solution isn´t so local

At this point it is important to split the management accounting IT. The topics of data collection and storage are to be separated from the communication of the results, the reporting. Collecting data in isolated applications must be called into question for many reasons. Each BI vendor can name these reasons. However, automated local tools solve many issues when creating reports and presentations.

Strictly speaking, local reporting tools are hybrids. The data they access is usually from centralized systems. The reporting is done in front-end tools that are individually designed and managed locally. The distribution of reports can also be automated and is not particularly limited.

The right time for individual reporting tools

Use custom reporting tools when management often needs to change report variants. They make sense if structured data from the DataWarehouse are to be supplemented with unstructured, individual comments and explanations.

In strategic management, variable reporting and presentation tools make sense in every case. But operational management also raises questions that can only partially be answered by centralized reports.

Resource requirements

There is a catch. As a rule, locally generated reports can´t created quickly. The efficient creation of local reporting tools usually requires a very long learning period.

The design and planning process requires fewer reconciliations and compromises between the report creator and the report recipient. That’s positive. The technical and creative implementation requires a lot of know-how. Specialized knowledge is needed that has little to do with management accounting in a business sense.

Knowledge of the data connection, automation and programming are essential. If the visual presentation and presentation should be efficient and at high quality standards, an above-average user knowledge is necessary.

An idea, if own resources are missing

But even without a resource pool of its own, the advantages of local reporting tools are easy to exploit. The development of such tools is an individual service for which there are different solution providers on the market. These are not software providers, but experienced service providers with special management accounting know-how and relevant experience in the field of reporting.

Good service providers provide a very high quality standard that meets your individual conceptual and technical requirements.

They work directly with the specialist departments in manageable project periods and deliver immediately ready-to-use solutions.

chartisan is one of these solution providers. Our focus is the Management Information Design with IBCS® and the technical implementation with the possibilities of Microsoft Office (Excel, PowerPivot, Power Query, PowerPoint) and Power BI.

Advantages and disadvantages at a glance

You have little time? Therefore is here a clear plus-minus list:

+ Local reporting tools allow variable reporting and presentations.

+ These reporting tools can efficiently display structured and unstructured data.

+ Local reporting tools are ready for use in short time.

+ Through the high degree of automation, the tools support the operative controlling routine.

+ You can buy suitable solutions externally as a targeted supplement to the standard systems.


– Through internal development you tie up important resources, time and financially.

– When using external service providers, you buy foreign competences.

– External service also costs money.

Portfolio diagrams can be created with the Excel „bubble“ diagram modus for many applications.  What makes this type of diagram special is that a total of three data dimensions can be visualised: X-position (horizontal), Y-position (vertical) and the bubble size (area).

Portfolios are primarily used if a quantity of data are to be segmented. In an investment portfolio, for example, factors such as productivity and risk index can be inserted on the axes, whilst the bubble size represents the investment volume. Typical portfolio applications include product/market observations, employee performance and strategic project management. In all such cases, visualisation enables easily recognisable sub-categorisation of data (products, projects etc.) in certain groups, combined with evaluation options for good/bad or preferred/not preferred. For example, high-risk projects with a low yield can be identified at a glance.

As in all diagrams, portfolios should be concise and informative. Easy to read labelling and precise highlighting play an important role. Unfortunately, standard functions for this are quite limited in the Excel bubble diagrams. We have thought up some good ideas to create professional and informative representation with a low outlay. Find out how to do this in the following.

  • Create a bubble diagram with a single data set (names of countries may not be marked)
  • Set axis length and gridlines according to requirements
  • Set data set colour to grey (neutral, no highlighting)

  • Develop formulae for automatic display/hiding of differently coloured data sets (grey, red, green) Hide using #NV


  • Change the data source of the first data sets, so that the bubble size is used from the previously calculated formula area
  • Insert and format two additional data sets with the corresponding source areas for red and green, only a few bubbles are visible in each of these data sets

Tip: Bubbles with a semi-transparent filling and white frame line are also easily identifiable when several data points intersect.

  • Insert an additional data set on the basis of the original source area and format it invisibly (no filling, no line), all bubbles in this data set are visible
  • Display data labelling for this data set and link with the cells containing names of countries

Tip: Linking works with the method from the article “clever data labelling”. For bubble diagrams in particular, it´s best to first click on one of the data labels and then press the cursor button (arrow) on the right. In this way, the first label field is accurately marked, which can then be linked with the first country names using “=” and a mouse click. Then move the cursor button to the right to the second label field and so on. As „column labelling” is not foreseen for the bubble diagram, the linked labels you made yourself are the only option. The labelling option “value from cells” is available from Excel 2013 onwards, allowing the same result to be achieved faster.

One of our previous posts discussed small multiples, i.e. a series of charts consisting of several small charts of the same type. It also describes conceptual considerations on typical application scenarios involving small multiples.

This post introduces an alternative method which you can use to create small multiples for simpler application scenarios at the blink of an eye. This type of alternative is especially interesting if the speed of implementation is more important that a special, individual chart design.

The idea: Excel sparklines are ‘opened up’ into a small multiple.

Sparklines are very simple diagrams nested within a single cell. Generally speaking, several of these charts are bundled together in a group, for which certain properties are defined, e.g. column colour or axis length. Use the following steps to transform standard sparklines into small multiples in a matter of minutes.

  • “Insert” menu -> Sparklines -> Column / select data and location range so the sparklines appear next to the input area for the values
  • Link the first sparkline with the first country name / copy the formula downwards for the other sparklines

  • Move the cells with sparklines into a cell range with the desired layout

The interim result doesn’t provide a good overview over the data yet because Excel automatically displays each sparkline with an individual axis. Therefore, the charts need to be given a standardised axis using the following option:

  • Click on a sparkline / “Design” menu -> Axis / set Minimum and Maximum value to the same for all sparklines

To increase the informational value, if required, you can also automatically display certain columns in a different colour, e.g. High Point and Last Point.

Done 🙂






Labelling data points in charts is generally more reader-friendly than using a vertical axis. The axis is automatically displayed in Excel, and therefore it is often found in reports and presentations. However, it forces the chart reader to move their eyes back and forth between the data points and the axis.

If data points are labelled directly, on the other hand, the reader’s eye can rest steadily on the data points. That way, readers of your charts can concentrate on the content (!). Unfortunately, standard labelling options in Excel are often too inflexible, and the results are quite ugly. In line charts, for example, there are often overlaps between label and line, and in the worst case, they are no longer legible.

Excel does offer different label positions (top, bottom, right, left, centred). But these are always applied to all data points at once, although an individual alignment per data point would make more sense. Of course, you can also move the labels manually. But this can also lead to problems, as the manual position also needs to be changed by hand after data updates.

A little trick provides the solution: an invisible auxiliary data range can be used to generate data labels that always position themselves correctly. In the case of a line chart, you can have it calculate whether it ‘bends’ up or down for each point. The formula then compares each data point with the median value of its two neighbours. Of course, you may have to use completely different formulas for different chart types.

Use the following steps to create clever labels for line charts:

  • Create a formula to move the label up (+1) or down (-1)
  • Calculate auxiliary data range “Label” for data labelling (at the points level)

  • Add data range “Label” to the diagram, make points and connecting lines invisible and insert centred data labels

  • Click the first label field of the new data range twice (don’t double click), so that the individual label field is selected
  • Type “=” and click on the table cell showing the value to be displayed (e.g. the value for January), then confirm with enter (this creates a so-called linked label)
  • Link the other data points with the corresponding table cells

Done 🙂

Tip: Excel Version 2013 introduced the labelling option “Value From Cells”, with which you can achieve the desired result much quicker.


In bar diagrams multiple streams of data can be grouped (side by side) or piled (on top of each other). Both display formats are important. Sometimes it is also practical to combine both forms. E.g. two piled columns side by side per month.

Due to the fact that the combination of piled and grouped columns is not available within Excel, we need our today’s trick to accomplish our illustration:

  • reserve a separate segment area for the streams of data of your diagram. E.g. two columns per month plus one column of space between months
  • Transfer the values from your input area into the reserved segment (via segment source or formula)
Template: Schrittweise zum Säulendiagramm mit Doppelstapel
  • compile a piled bar diagram from the specifically built formula
  • Adjust the space width of columns to a very small value such as 5%
  • As needed pigment the columns and fade in captions

  • Add legible sums and legends (see our trick “captions”)

It´s mostly about variations when presenting data to decision makers, such as planned, target or empirical values. Only these variations allow us to reasonably evaluate the actual numbers.

Variations should play a major role during the visualisation as well. Today´s trick shows us that this is feasible within Excel only with a few clicks in specific cases:

  • Compile a diagram with two curve streams of data

  • Mark the diagram and add the variation columns by choosing the menu diagram draft
  • Format the variation columns red or green respectively. The column width can be adjusted to one of the curve stream of data by right click. (parameter “space width”)

  • Add data caption and legend if applicable (see our trick “captions”)

Data captions and legends are important to understand the content of diagrams. Unfortunately the provided alternatives to caption are partially not legible. For example, sums on top of piled columns are not provided. You search in vain for standard functions such as legends which support the viewer not to look back and forth as they are placed directly next to the stream of data.

With our today´s trick it is possible to implement legible and at the same time dynamic captions:

Part 1: Sums on top of piled columns

  • Calculate sum values and insert as new stream of data (right click on diagram, “choose data”, add stream of data)
  • Change stream of data type to “XYZ” of the new stream of data (right click on new column, choose “Change stream of data type”)
  • Invisibly format items and fade in the data caption on top

Part 2: Legend next to piled column

  • Fade out the standardised legend
  • Extend the column stream of data to an area with empty segments, so that there is enough space for the legend next to the last column
  • Calculate the X- and Y- coordinates for the legend text, depending on the data of the last column (see sample data file)
  • Insert a stream of data of the type “XYZ” (as in part 1)

  • (The X-values for the horizontal alignment of the points, can be divided into the data source capture only after the type “point XY” is selected)
  • Formatting points invisible and show data label right
  • First data label of the new data series, click twice (not double), is so marked a single label area
  • “=” type and click on the table cell in the desired legend text is, then Enter to confirm

  • Connect the remaining legend texts with the equivalent chart segments

In many cases it is important to allocate data to multiple diagrams so the presentation is clear. It results in so-called Small-Multiple illustrations.

If each single diagram uses its own scale, the informative value of the entire page will get lost. In terms of a high quality visualisation, unitary scales are very important. At the same time the diagrams should be of low-maintenance and dynamic.

This challenge can be managed in Excel with our today´s small trick:

  • Calculate the minimum and maximum of all (!) single values (function MIN and MAX)
  • Insert into each single diagram the minimum and maximum values as an extra data stream
  • Invisibly format the minimum and maximum data stream (no filling, no frame line)
  • Align diagrams of same size next to each other

(keep holding the alt-key when pulling the mouse; then your diagrams lock with the segments)
