Sample text

The underlying metric values remain unchanged. If we want the value of the metric to be in thousands or millions, we divide the expression by 1,000. For example, Sum ([Net Sales])/1000. We now have a clear, simple rank analysis as shown in the following image: Rule 2 – convert color into data We resist adding color just to make charts flashier. We lose a great opportunity to add insightful data if we color each bar differently, or use a corporate color scheme for no other reason than to make it pretty.

3. Click on OK. The word net sales is redundant data-ink; however, it is not redundant usability-ink. If we eliminate the word net sales from the metric labels and then export the chart to Excel, we will lose all mention of net sales in Excel. Finally, the caption background and border is not data-ink, but it is usability-ink since we use these elements to easily move and resize the chart. The default pale gray used for these elements is perfect. We resist making these elements follow a corporate color scheme since most corporate color schemes contain dark, vivid colors that distract from our data analysis.

In short, we consider chartjunk to be any pixel that is neither data-ink nor usability-ink. info Chapter 2 By default, QlikView creates bar charts with little chartjunk. It is therefore our job not to ruin what Qlikview does well. In our most recent bar chart comparing 2013 net sales with 2012 net sales, the following items appear to be either redundant or non-essential: • The print icon on the right side of the caption is rarely used • The word net sales is repeated twice: once in the legend and again in the caption • The caption background and border around the graph are decorative The print icon is a waste of space.
