After completing this lesson, you will be able to:
Create charts in a story to display your data graphically. As shown in the following figure, you can select a chart type from the builder and then pick the measures and dimensions to show in your chart. Once you have defined the structure of your chart, you can add other chart elements and/or filters. You can also customize color palettes.
You can choose from many different types of charts.
You are responsible for creating visualizations to meet a variety of business requirements for you team.
You need learn how to configure charts and work with chart features that the users will find helpful.
In this practice exercise, you will:
Chart scaling ensures that you have a meaningful display of values across multiple charts. By default, charts are not scaled. However, this behavior can lead to incorrect data analysis, particularly if users are not paying attention to the actual values displayed in the chart.
NoteChart scaling is applied to all of the pages in a story, but the scaling may be different for the same measure on different pages, because the scaling factor is calculated separately for each page.
You can exclude charts from the scaling. For example, if a chart contains data that is much larger than the data in other charts, the other charts look smaller than they should, and could be misleading to the viewer.
By default, charts are not scaled, so you to ensure correct data analysis you want add chart scaling to your story.
In this practice exercise, you will:
Variances in your charts let you show the difference between different measures in a chart, different versions of a measure, or the difference between time periods for a measure.
As illustrated in the following example, you can use the variance chart add-on for any two measures, even if the measures do not appear in your base chart.
You can also create a dynamic variance, a variance that is based on the measures in the chart context. If you change the measures in the chart, the variance automatically updates.
NoteTo include time in your variance, you must have the Date dimension in your chart.
For some chart types (numeric point, for example), when the variance uses a Time Range filter, the range must be set to only one interval (year, quarter, or period).
When using models from live data connections, you must include version information with your measures, and your measures must be in your base chart.
You want to use variances in your charts show the difference between different measures in a chart, different versions of a measure, or the difference between time periods for a measure.
In this practice exercise, you will:
A trellis add-on creates the same chart for each member of the trellis dimension.
In the following example, you can see a trellis add-on in a classic story.
NoteYou decide that you want to create a trellis to dynamically create many charts for a selected chart for better data visualization. This will allow for better data comparison in your story.
You also decide that you want to add tool tips to the chart for your report viewers.
In this practice exercise, you will:
If you delete a widget in your story, you can restore it, but how you restore it depends on which design mode you are using – Optimized Design or Classic Design.
To restore a widget you have deleted, use the 
Undo button in the main toolbar. Undo reverts any previous action, from adding/deleting widgets to configuring them.
To restore a widget you have deleted, you must immediately choose the Restore link in the message at the bottom of the screen:
