Charts (Pro) allow you to configure global settings for charts and configure personalized display settings for the results of a single query statement or for a single column of data in the results.
Common Settings tab
On the Common Settings tab, you can configure global settings for a chart. The settings take effect on the chart that is generated based on the results of all query statements.

Fields tab
On the Fields tab, you can configure personalized display settings for the results of a single query statement or for a single column of data in the results. The settings are chart attributes and take effect only on the chart that is generated based on the results of the selected query statement or based on a single column of data in the results.

Differences between the Common Settings and Fields tabs
The two tabs provide similar configuration items but differ in the applicable scopes of the configuration items. Settings on the Common Settings tab take effect on a chart that is generated based on the results of all query statements. Settings on the Fields tab take effect on a chart that is generated based on the results of a single query statement or on a single column of data in the results.
For example, you want to display the numbers of page views (PVs) for two websites within the current hour in a line chart and you want to distinguish between the numbers by color and legend. If you configure Display Name and Color Scheme on the Common Settings tab, the line segments for the two websites have the same color and legend name. As a result, you cannot distinguish between the numbers. In this case, you can configure personalized display settings on the Fields tab to distinguish between the numbers.
- Common Settings tab
If you set Color Scheme to Solid and Display Name to PV, the colors and legend names for the two line segments are the same.
- Fields tab
- You can add the A > pv field to configure settings for the line segment that represents the PV data in the query and analysis results of Website A. You can select the red color for Standard Configurations > Color Scheme and enter PV of Website A for Standard Configurations > Display Name.
- You can add the B > pv field to configure settings for the line segment that represents the PV data in the query and analysis results of Website B. You can select the yellow color for Standard Configurations > Color Scheme and enter PV of Website B for Standard Configurations > Display Name.
