Nada mudou....

Já faz tempo, que saiu a pesquisa 

"29ª Pesquisa Anual do Uso de TI, 2018" da GVcia, FGV-EAESP

https://eaesp.fgv.br/sites/eaesp.fgv.br/files/pesti2018gvciappt.pdf

Porém em relação aos anos anteriores* nada mudou ("as-normas-ibcs-e-realidade-brasileira."). As inconsistências em relação às IBCS continuem..

A apresentação dos dados desta forma para o leitor é interessante e mais nada... Mas poderia ter sido muito mais, se os autores tivessem organizados as informações em outros tipos de gráficos. Neste caso em gráficos múltiplos que mostram as situações dos vários anos em uma página só. Assim o leitor deveria ter percebido rápidamente que o market share da SAP no segmento de 170 a 700 teclados vem crescendo desde 2011/12 de 21% para 28% em 2017/18. Na forma de hoje o leitor tem que consultar 3 slides de 3 relatórios diferentes para chegar à mesma informação......E nos tempos de hoje alguém faria isso?

Is there Progress in Information Design?

 William Playfair more than 200 years ago used paper, ink and his brain as primary sources for his charts.


Today we use computers, charting software and obviously not that much brain for the same output....



So it seems that there was little progress during the last 200 years when it comes to information design, considering the chart results from todays authors.




Fortunatelly the situation is not that bad since Edward Tufty introduced for example “small multiples” (as shown in an example above from Jorge Camoes) and IBCS with Rolf Hichert and his community in the field of business communication are working hard in bringing the visualisation of content by notation principles to a broader public.

IBCS by SAP


As normas do IBCS agora também estão representadas no num front-end de BI da SAP – o SAPAnalyticsCloud. O expert Ingo Hilgefort mostra numa série de cinco artigos como os “Top 10 IBCS Standardization Elements” podem ser entendidos e como se encaixam dentro do SAPAnalyticsCloud.

Scaling – cut the axis...


Scaling is a very important item of the IBCS rules. When it comes to present extreme values for example very high income in one region and very low in other regions the normal way in a column chart was to cut the column in the middle applying a symbol like that //  




Not necessarily the best solution as we lose the magnitude relation between the charts.

By introducing a scaling area as shown in the next chart we maintain the relations and the reader still can imagine the proportions.



The next chart shows a very “tricky” way to solve the problem. Instead of cutting the column just cut the x-axes. As we can see by applying this we maintain the same proportions and everything fits in the chart.

About line charts



About two months ago at www.storytellingwithdata.com there was a contest about annotated line charts and almost 100 contributions were accepted. 

 http://www.storytellingwithdata.com/blog/2018/1/22/88-annotated-line-graphs

As we can see there wasn’t that much creativity involved.

New approaches like multicharts with/and “timelines” are very rare.

And here are the good news: IBCS goes mainstream

The first good news is that SAP Analytics Cloud is now IBCS/Hichert certified.



For those interested in applying visualization standards in their reports SAP offers now within their Analytics Cloud IBCS compliant charts.





It is no longer necessary to use third party tools within your SAP environment in order to produce highly sophisticated reports and dashboards.
For more information see the article of Blaž Zabukovec (https://www.linkedin.com/pulse/sap-analytics-cloud-now-ibcshichert-certified-success-blaž-zabukovec/) the official SAP announcement
  
 ZebraBI-PBI




The second good news comes from ZebraBI which now offers a visuals add-on for Microsoft PowerBI. The fast growing PowerBI community can now use sophisticated IBCS-charts for reporting and dashboard design. As can be seen on a recently held Webinar (https://zebrabi.com/power-bi-webinar/#av_section_2) ZebraBI custom visuals do a great job in accelerated dashboard design.
