Creating Error Scatter Chart
An error scatter chart is an XY plot chart with vertical and horizontal error bars to show a range of error values for a specific data value.
In this section you will be shown how you can:
-
Create a simple error scatter chart
-
Customize the vertical and horizontal error bars
Creating a Simple Error Scatter Chart
As an example, we will create a simple error scatter chart that shows the revenue forecast for the next year.
An error scatter chart thus created looks like this:
Given below is a brief description of the attributes used to create an error scatter chart:
| Attribute | Description |
|---|---|
|
It is used to specify the label for the data item. The label is rendered on the x-axis. This attribute belongs to the |
|
In the error scatter chart, the position of a datapoint is defined in the form of two numeric parameters, one from the y-axis and the other from the x-axis. |
|
When used with the |
|
It is used to specify the numeric |
|
It is used to specify the radius of the anchor that represents the data point. |
|
It is used to specify the hex code of the color that will be used to render the anchor that represents the data point. |
|
It is used to specify the range of possible vertical deviation values that will be plotted as the error bar on the chart. This attribute belongs to the |
The data structure for creating the above chart is given below :

}Customizing the Error Bar
You can customize the cosmetic properties of error bars to change their appearance.
An error scatter chart, after customizing the error bars, looks like this :
Given below is a brief description of the attributes used to customize the error bars::
| Attribute | Description |
|---|---|
|
It is used to specify whether vertical error bars (half/full) will be shown for the error scatter chart. Setting this attribute to |

}There! You have now seen how you can create an error scatter chart and customize the error bars.
