Configure Insight Properties
Analytical Designer allows you to change the default properties of your insights. You can show or hide axes, disable gridlines, rotate labels, change colors, and so on.
You can change the properties in the Configuration section when creating an insight.
- To hide or display axes, toggle the switch for the x-axes and y-axes.
If you enable a secondary axis for bar charts, column charts, or line charts, you can configure the secondary axis here as well. For details about the secondary axes, see Bar Charts, Column Charts, and Line Charts.
- To change the display angle of the axis values, select the angle in the Rotation dropdown list.
- To hide or display the axis name, toggle the switch for Name.
- To change the position of the axis name, select the option in the Position dropdown list.
- To set the minimum and maximum values for an axis, type the values in the Min and Max fields.
- To hide or display the legend, toggle the switch in the Legend section.
- To change the position of the legend, select the position in the dropdown list.
- To show or hide the data labels, select the option in the Data Labels dropdown list.
- To show or hide the gridline, select or unselect the Gridline option.
Change Measure and Attribute Colors
Analytical Designer assigns colors for measures and attributes in a fixed order. The first measure/attribute in the Measure(s) section is assigned the first color from the palette (the default one or your custom palette).
For each measure/attribute in your insight, you can change the color in which the insight displays it. For example, you want to display
Opportunities won in green and
Opportunities lost in blue.
In the Configuration section, click Colors (
Ain the image above).
Click the measure/attribute that you want to change.
Select a new color, or click Custom color (
B) to adjust the current color.
You can select another color form the picker (
C), enter a hexadecimal code for a new color (
D), or select a different shade of your color (
To revert to the original colors, go to Configuration → Colors and click Reset colors.
Use data sampling to quickly determine the viability of a particular insight by processing only a percentage of the total available rows in the associated datasets instead of processing all of the data. Data sampling can be enabled at any point during the analysis, but enabling the option before you build the insight will provide the most benefit as insights are built dynamically according to input.
Data sampling creates a smaller set of data from a much larger set of data. Because the rows are chosen randomly, the results are unstable and therefore unsuitable for persistent objects like insights and dashboards.
Insights cannot be saved with the results from data sampling. The option must be re-enabled whenever you leave the analytical designer.
- Data sampling is available only for workspaces that use Vertica Data Sources.
- Data sampling is available for use only within Analytical Designer and through the API.
- If the physical data model associated with the logical data model contains a view, data sampling is unavailable.
- Enable the data sampling option.
- Set the sample size percentage. The size must be a number greater than 0.0 and lower than 100.0. The selected percentage of rows will be used when computing the insight.
Because only a percentage of the total rows are used in the computation and the decision of which rows to use is random, setting a low sample size with a small set of data can result in 0 rows being used during computation. Adjust the values until you receive usable results.
- Select apply.
- Build your insight.
Example of a Column Chart
The image below shows a column chart that has:
The color of the measure changed
The x-axis switched off
The labels on the y-axis (left) rotated by 30°
The scale of the y-axis (left) set between 0 and 50000
Dual x-axes are available for line charts. Dual y-axes are available for bar charts and column charts.
The legend placed to the left of the insight
The data labels displayed
The gridline hidden
