Plotting Curve Plots in the Data Manager

Curve plots are one of the plots available on Rulex Platform. Their name comes from the way data are represented: a curve.

Prerequisites

• You must have created a flow;

• You must have linked the Data Manager to a task which contains the data to work on.

Procedure

1. In the Plots tab of the Data Manager, click on the plus button to add a new plot.

2. Select the plot type and choose the Curve Plot.

3. Drag the required attributes onto either the x or y axis, or both. If you want to build more complex plots, follow the guidelines listed below.

4. If required, work on the attributes on the plot, for example to modify their values.

5. Configure the plot options, if required, by right-clicking on the single plot elements' icons.

6. Hover over each bar to view the number of values it represents. If you place your pointer on the bars, a small box showing the count of the values appears.

7. Modify the display options, if required.

8. Click on the wrench button to configure the overall layout settings.

9. Save and compute the task.

Customization constraints

• If you drag a second attribute on an element of an existing plot, the first attribute is replaced by the new one;

• If you drag a second attribute on an element of an existing plot, hold down the CTRL button on your keyboard when dropping the second attribute to create another plot with the new attribute on the chosen element.

• If you drag a second attribute on an element of an existing plot, hold down the SHIFT button on your keyboard when dropping the second attribute to add the second attribute to the same plot, so that one element will contain two attributes.
  You can decide to separate the attributes onto two different plots, by right clicking on the attribute and selecting Detach. If you want to merge the two attributes again, right click on the second attribute and select Attach.

To know more about the plot’s elements, go to the Elements page.

Example

This example uses the Students Performance dataset.

Step	Screenshot
Add a new plot and drag the required attributes onto the elements. In the example here, we decided to drag the writing score attribute onto the x axis and the test preparation course attribute onto the color target element.
If you place your pointer on the plot, the number of times the value is repeated is shown. If divided by color, the name of each value is shown next to the number it refers to. In the example here, 126 people whose writing score is 60 didn’t take any preparation course, as the value next to 126 is none. 43 people whose writing score is 60 completed the preparation course.
