I'm using IMPORTDATA and my live-updating chart is not updating
If you are:
and having issues where your live-updating chart is not appearing or is not updating, this tutorial will hopefully explain why and provide a solution for you.
If you're using IMPORTDATA to load a link to another sheet or a CSV data, it takes a few seconds for the data to load while the sheet displays " loading..." and the cells remain empty:
This happens especially when you have a large dataset. When this happens frequently enough to coincide with when Datawrapper is scheduled to retrieve data from the linked spreadsheet every minute/hour, Datawrapper will update the chart's data with empty cells instead of actual values that can be plotted. This results in an empty chart or missing data in charts.
A solution to this would be to use the Google Apps Script to write a script that will only replace the values when the updated data is loaded and ready to be displayed. To read how to do this, visit the academy articles below:
