Overview
A Category scatter chart is a scatter chart that displays a pair of category series that has the same category variables. It displays the series as coordinates, where one series is placed on the x-axis and the other on the y-axis. A point represents the value of both series for one category. It is typically used when displaying the results of a Scalar analysis.
Chart elements:
- Points/Graph
- Main title
- Graph area
- Vertical value axis (y-axis)
- Source logo & text
- Chart background (outside chart area)
- Horizontal value axis (x-axis)
- Legend
Settings
To edit any one of these components, click on it, and the available options will appear at the top of the window, under the presentation properties tab.
Graph settings
When you click on any point of the graph, the settings that become available under the Presentation properties panel are especially relevant to fine tuning the look of your graph. In the appearance box, you can customize the style and color of the graph display, for example selecting whether you want a line or markers in the case of a line graph, and the size of the bubbles in the case of a bubble chart.
Here, you can also limit the range of categories displayed for the graph you have selected t by specifying category numbers under Data range. You should use the “#” symbol to specify category index values or use relative index values such as -1. The display range #2 to #5, for example, will display the second to the fifth categories, based on their order in the series.
Graph layout
You can access this window by right clicking on the chart and selecting Graph layout (or Ctrl+L).
Here, you can define how the graph should be displayed (line or bubble) as well as which series corresponds to which axis. On the right side of the window, the graphed pairs of series are displayed under a graph type. The first series of each pair is placed on the x-axis and the second one on the y-axis. Click and drag to move them if you want to switch the axes.
Line chart
When graphing the same pair of series twice in a chart (if, for instance, you would like to display two ranges of time in different color) it is important that the series are in the same order, as in the picture above.
Bubble chart
The bubble chart requires a third series to be added last in the list. This third series will define the relative sizes of the bubbles. For more information about this type of chart see Bubble chart.
Chart settings
These settings can be accessed after clicking outside chart area.
Appearance > Margin
This panel of settings manages the distance between elements on the chart. Indentation defines the minimum distance from the leftmost/rightmost side of the chart and the left/right side of the graph area.
What analyses work with this chart type?
All types of analyses which remove time parameter and turn series into category series or use such series.
Example
In this example we presented available types of charts.
Questions
How to change connected line to dots?
Click on the line in the chart and look under the Appearance group in Presentation properties.
Here, you can change the Graph style from Automatic to Custom and choose the style you’d like. You can remove the line between observations by setting its thickness to None and add a Marker style and size.
How to highlight an observation?
You can highlight observation on a category scatter chart in one of three ways, depending on how you would like to highlight it. With option 1, you can circle the point and add text. With options 2 and 3, you can change how the point is plotted, and change its shape, color, or size.
- Using an Observation label
a) Having your scatter chart selected in the analysis tree, right-click on any point and select Add observation label.
You can also go to Chart annotations > Annotations, select Observation label and click any point on chart to add an observation label.
b) Double click on a label to change its content. For more information see: Dynamic text
c) Edit the style of the label by ticking the 'Custom style' box under the Presentation properties panel. - Plot the same scatter line again and only show the last value on the chart
a) Open the Graph Layout and add another Line graph type with the same time series (make sure they are also in the same order).
b) You will not have a line so you need to turn on markers for that line. Adjust the appearance by changing under Presentation properties > Graph style from Automatic to Custom, selecting Line: None and setting Marker style and its size.
c) Keep that line selected. To limit the range displayed go to Presentation properties > Data range. You can show only the last value by typing position (i.e., #1) into both fields. Note you can also select more than one position and type in '#1' and '#3' leaving three points.
- Use formula language to turn entire series into a forecast, then change how forecast values are presented on the chart
a) Type the following formula into the Series list or an inserted Formula analysis. This flags entire series as forecast :FlagForecast(fx:s1)
b) To change how forecast values are presented click on the graph in the Scatter chart, select Presentation properties > Appearance > Graph style: Custom > Forecast
How to show only one date/value in label?
Our labels use Dynamic text feature. The default text for a label is:
{s .Date -m -s " "}{s .ValueLabel -m -s " "}{s .Value}
On the right, under Dynamic properties, you can find 'All series' drop-down menu. There you can find alias for each series. In Macrobond they are named s1, s2, s3, etc. To show Date or Value for a specific series just add this alias before dynamic text:
{s s1.Date -m -s " "}{s s1.ValueLabel -m -s " "}{s s1.Value}
