The Data Set Plot block lets you display charts of the data stored in the Data Set
attached to its action link.
Configuring
When you choose configure from the block's menu, and you have attached a Data
Set to its action link, the block displays the configuration panel below.
|
The following headings describe how to interact with the configuration panel.
Choosing What to Display
To specify what data from the Data Set is displayed on the chart, specify one of
these options for X Axis and Y Axis:
If the data set has more than one column of data for the option you selected, enter
the number for the column you want displayed in the field under the options.
Choosing How to Display the Data
To specify how the data is displayed, use the options on the right of the dialog.
Choose the type of chart from the options listed under Chart Style. You can
choose a line, scatter, or column chart, as shown below.
|
To put a marker on each point in a data series, choose one of the options listed
under Indicator. If the Chart Style is Line, you can choose any of these options. If
the Chart Style is Scatter, the option None is not available. If the Chart Style is
Column, only the option Column is available. The chart below shows you what
the indicators look like.

The bar and column indicators are a little different from the rest. They draw a line
from the point to an axis. A bar goes to the Y axis, and a column goes to the X axis,
as shown below.
|
To choose a color for the data series, use the Color list. It contains all the available
G2 colors. You can scroll through the list by using the scroll bar on the left. The
names of the unselected colors are black. When you select a color, its name
becomes white.
Choosing Where to Display the Data
To specify the chart to display the data on, enter the chart's name in the attribute
Chart Name.
G2 as the chart name, the Data Set Plot block creates a subworkspace
for itself and places a chart on that workspace, as shown below. To hide the
subworkspace, click the Hide Plot button.
|
Creating and Deleting Data Series
Sometimes you might want to display more than one view of your data on a
single chart. For example, you might want to plot a view of the inputs versus the
targets, and a view of the inputs versus the predictions. Each of these views is
called a data series. The second line from the top of the dialog displays which data
series you are editing and how many data series there are for this data set. (For
example, if the second line reads "Data Series 2 of 3," there are three data series
and you are editing the second.) The buttons in the lower left corner of the dialog
let you create, delete, and move between data series.
Making Values Permanent
When you choose make permanent from the block's menu, the block saves the
data set.
Example
In the diagram below, the Data Set Plot block graphs the progress of the Fit Test
block. The Data Set Plot block has two data series: one to show the target values
and one to show the neural net's predictions. In the first data series, the X Axis is
inputs, the Y Axis is predictions, the Chart Style is Line, and the Indicator is None.
In the second data series, the X Axis is inputs, the Y Axis is Targets, the Chart
Style is Scatter, and the Indicator is Square.
