Hello,
before the update to the latest, I was able to push new data into the visualizer like this
var t = visPanel.getVisualizer(questionName);
t.options.dataProvider.data.push(newAnswer);
t.options.dataProvider.raiseDataChanged();
that does not work anymore, I have tried the visualizer.updateData with no luck. How can I get a new set of answers pushed to the visualizer and refresh the graphic?
Thank you
Manuela
Hello Manuela,
The code snippet you've shared actually uses internal and undocumented APIs. We don't recommend directly updating the dataProvider.data object.
If you wish to update an array of survey results visualized by the Analytics panel, we suggest that you use the VisualizationPanel.updateData method. This updateData method updates the entire visualizer data. So, if you wish to add another question answer to the survey result, simply add a new entry to the original survey result JSON and pass the updated JSON to the updateData method:
JavaScriptconst surveyResults = [{
"satisfaction-score": 5,
"nps-score": 10
}...];
...
updateResults = ()=>{
const newAnswer = {'satisfaction-score': 4};
surveyResults.push(newAnswer);
visPanel.updateData(surveyResults);
}
A complete example is available here.
Please let me know if this works for you.
Hello Jane,
I was using updateData on the visualizer not the panel. Thank you!
However, it does not work for custom visualizers. I assume I am missing a step.
Hello Redlof,
Thank you for the update. I tested this and confirmed that the survey result is not updated when using a custom visualizer. We'll update the following GitHub issue once we have any news to share: The VisualizationPanel.updateData method doesn't update survey results when using a custom SurveyAnalytics.HistogramModel visualizer.
Please let me know if you have additional questions.
Thank you,
Jane
