Ideally, when you flip to a pie/donut chart for a matrix question, each pie/donut represents a "row" in the matrix, which is really a question on the survey. This is how the chart renders in a bar chart, which is correct:
However, when switching to a pie/donut (in order to see percentages of responses, which is important), the pies/donuts are organized by response type, not by question. Ideally each pie/donut below is a question vs a response type.
Hello,
I suggest that you use the allowTransposeData option to visualize a matrix by rows. Please refer to the following demo: View Plunker.
JavaScriptconst vizPanel = new SurveyAnalytics.VisualizationPanel(
survey.getAllQuestions(),
dataFromServer,
{ allowDynamicLayout: false, allowHideQuestions: false, allowTransposeData: true }
);
vizPanel.unregisterToolbarItem("resetFilter");
vizPanel.visualizers[0].setChartType("pie");
vizPanel.visualizers[0].transposeData = true;
Let me know if this option works for you.
