Differences between the General Configurations and Field Configuration tabs
The two tabs provide similar configuration items but differ in the applicable scopes of the configuration items. The settings on the General Configurations tab take effect on the entire chart. The settings on the Field Configuration tab take effect on the results of a single query statement or a single column.
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 General Configurations 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 Field Configuration tab to distinguish between the numbers.
General Configurations
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.
Field Configuration
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.
