Calendar Chart

Sales by Day

A Calendar Chart is a Heatmap-like visualization where the values are visualized as colored cells per day. Days are arranged into columns by week, then grouped by month and years to form a heatmap in the layout of a calendar.

Working With Calendar Charts

Drag the time related attributes into the layout panel
Note: You can either place a date field in the Date shelf, or you can drag individual Year/Month/Day attributes into the corresponding shelves. When using the individual Year/Month/Day attributes, you minimally need to provide a Year and a Month.
Drag a measure into the 'Color By' shelf indicating the measure by which you want to color code the month(s) or day(s). Colors will be assigned by default in a gradient pattern from Green (highest value) to Yellow to Red (lowest value).
Drag a measure into the 'Size By' shelf indicating the attribute you want to base the size of the circles on.
Note: You don't need to assign both a 'Color By' and a 'Size By' attribute, you can assign either/or/both.

Click on one or more circles in the calendar chart to filter data using the fly-out filtering bar (Keep Only|Exclude|Clear Selections)
The follow chart properties are provided to further refine your visualizations:
- Pattern - selecting the Gradient pattern will color values using a smooth range of colors along the color range specified by the 'Color' chart property. The step options plot all values using one of 3 or 5 colors according to the 'Color' property
- Color - select the color range to use for color coding the values on the chart
- Reverse colors - check to reverse the color range. For example, instead of Green (highest value)|Yellow|Red (lowest value), check the box to color values by Green (lowest value)|Yellow|Red (highest value)
