  2. Build a query.
  3. Set the data definitions: values, series, category.
  4. Select a chart type and theme.
  5. Enter labels for the chart title, and x,y axes.
  6. If applicable, adjust scaling and label rotation.
  7. Place your chart in the dashboard.
  8. Save your dashboard.

See Create a Chart in the Dashboard Designer for further details on these steps.

If you are new to charting, here are guidelines that may help you determine what type of chart is best suited for the data you want to present in your dashboard:

Bar Charts

If you want to compare items during a specific time period, consider using a bar chart. Key words to think about when creating a bar chart are compare or rank. For example if you want to compare items sold to show which one made the most profit, you might create a bar chart that ranks the products from the lowest to highest profit. The bar's length determines its ranking; the label identifies the item. Bar chart data can be presented horizontally or vertically depending on your requirements.

Pie Charts

If you are comparing parts of a whole, consider using a pie chart. Key words associated with charts include, portion, share, and percentage. If for example, you want to demonstrate the proportion of the company's budget spent on health insurance, use a pie chart. To make the chart easier to read, limit the number of slices to five. Pie charts can also be exploded, which means certain slices are pulled away from the remainder of the chart for emphasis.

Line Charts

Line charts are useful for showing changes over time. Key words associated with data that is best suited for a line chart are trend, growth, and decline. If, for example, you want to show how product sales have changed over five years, use a line chart. The slope of the line helps users quickly identify the direction of the trend.

Dial Charts

Dial charts are often associated with Key Performance Indicators (KPIs). Dial charts are circular and contain a scale, a needle, and one or more a dial sectors. The dial sector is used to identify a specified area on a dial chart using a particular color. For example, you could have a dial plotting inventory with a minimum dial value of 10000 and a maximum dial value of 50000. There could be a red dial sector for the region between 2000 and 4000 indicating that if the needle is in this area, there is a danger of a supply inventory shortage.

Area Charts

Area charts can be used to show a comparison of the same thing during different points in time. Area charts are not designed to provide exact data but they do give users visual clues of the relative sizes of the items they are representing.

Modify Charts

After creating a chart, you can perform any of the following modifications:
