Mix Chart¶

The Mix Chart widget is used to display the changes in data over a period of time or compare multiple sets of data. The mix chart supports presenting data in line chart, bar chart, target chart, scatter chart, area chart, bubble chart and dot-line chart.

Data Fields¶

The data fields required are:

Field	Quantity
Dimension	1
Comparison	0 - 1
Measurement	≥ 1
Extension	Unlimited

If the Measurement data values exceed two decimal places, they will be rounded off to 2 decimal places.

The Comparison data field enables you to segregate the data by their Comparison value and plot them as multiple charts on the widget. For example, the chart below shows how the data is separated into Measurement_A and Measurement_B.

You can also show/hide the charts according to their measurement data fields or comparison value by clicking their respective legend labels.
