A Scatter Chart Widget displays information as a series of data points. It is similar to an Line Chart, but without the data points connected by line segments.

How To Create a scatter Chart Widget

For instructions on creating a Widget, see the general instructions in Adding Widgets. The Scatter Widget type is located under the Charts category on the Widget selection screen.

How To Configure a Scatter Chart Widget

Follow the instructions above to create the basic "Scatter Chart" Widget, and then perform the following steps to configure a Scatter Chart Widget:

Select a Data Collection

Select a Data Collection that contains the information you would like to use for this Widget.

Click the "Data Collection" pulldown, then select from the list of available Data Collections.
If you're using the sample CSV data, select "Sample.Data.ChartData".
If there are no Data Collections available in the pulldown, then click here for instructions on how to bring in some Sample Chart Data, or refer to Add/Edit/Remove a Data Collection.

Configure the X-Axis

Select the desired Field to use for the X-Axis of the Chart.

The "rows" of this column of data will make up the X-Axis.

If you're using Sample.Data.ChartData, then select "Month" to be the Field.

Type

Select an option for Type from the drop-down box. This will be used to determine how the data is translated by AppBoard into the labels that are shown along the x-axis:

LinearAxis: x-axis values are determined as a linear progression between the lowest and highest values.
LogAxis: x-axis values are determined as a logarithmic progression between the lowest and highest values. Labels on the logarithmic axis are even powers of 10.
CategoryAxis: This is the default. The "rows" observed in the selected column of data will make up the X-Axis.
DateTimeAxis: x-axis values are determined as time-based values such as hours, days, weeks, or years. This value can be chosen or "auto" can be used to let the widget decide the best value to use. An option to change the date-time format is also available.

If you're using Sample.Data.ChartData, then select "CategoryAxis" to be the Type.

Configure a Series (Y-Axis)

Click the "Add" button in the button toolbar of the Series DataGrid.
Repeat to add additional series.
Series may be removed with the "Remove" button next to the "Add" button.
Series may be reordered in the Series DataGrid by clicking the upper-right corner of a row and dragging the Series up or down the grid.

Y-Field

Values contained within the "Y-field" will determine the height for that series.
If you're using Sample.Data.ChartData, then select "Software" as the Y-field.

Color

Color will work in conjunction with Fill Style to distinguish one series from another.
You can select color by clicking on the color swatches in the color picker, or you can manually enter a hexadecimal color value.

Alpha

Alpha sets the opacity of the series.
Reducing the Alpha lets you see grid lines show through the columns.
