IBCS-like area charts in Pyramid compare two measures, and show only upward and downward differences between their values. You can change the color corresponding to each in the Formatting panel. Values are displayed on the chart, with the final difference on the right hand side. Additionally, you can hover over sections of the chart to display specific values at that point, and the value of the difference.
Using IBCS logic
Because IBCS-like charts compare the difference between values of two measures, you must add a second measure to the Values panel. Once you have two measures in Values, click on the button corresponding to the IBCS chart type you want. The second measure is moved to a separate panel, called Additional Values:
See the Line Chart page for more information on creating a line chart:
The above chart shows turnover for a period of several months, comparing it with the operating budget, which is shown as a dotted line, running along the middle of the chart (indicated by the purple arrow). The turnover fluctuates, in some months being less than the budget, sometimes greater, The final date point on the chart also displays the % amount by which the turnover is less than the budget (orange arrow) - 19.5% in this case. Hover over any point on the chart to display the actual turnover, the budget, and the difference (delta) between them.
Note: To display the difference between the measures correctly, you must use the "IBCS" theme. This is available from the Themes on the Design tab.
