Chrome - Big data: when trying to export a large set of data the export is not succesful and there is no error #107

On Chrome - When trying to export a large set of data the export fails and the file cannot be downloaded.

Demo: http://jsfiddle.net/cqjvD/1260/ Steps:

  1. download CSV
  2. file is not download and a browser informs about network error.

Is there a known limit for the exported data? 150k data points seems to be too big - the fail occurs.

Could there be at least some kind of info about the fail?

Browsers: Chrome - the affected browser, IE11 and Edge - hangs for a while but handles it, Firefox - runs smoothly even with 1 million points.

Workaround

Use the boost module, works like a breeze: http://jsfiddle.net/highcharts/cqjvD/1261/

Interesting. I got a bug similar to Kacper's, but after investigation boost module turned out to be the culprit. Whenever your data exceeds boostThreshold, csv and excel exports return empty data sets. Internally getDataRows seems to return only two rows then. It happens both in my project and your jsfiddle: http://jsfiddle.net/highcharts/cqjvD/1261/

Hi there,

I ran into this problem too except when trying export large files as xls. I came across this solution and it worked for me: https://stackoverflow.com/questions/39374157/angular-save-file-as-csv-result-in-failed-network-error-only-on-chrome

Any chance we can get this fix in?

Yeah - I'm still seeing this problem with export-data from HighCharts 6.1.0 with Chromium 62.

Hi @nikolas

The repository is depreciated.

Given the popularity of this plugin, it has been taken in as a Highcharts module since v5.0.11 (2017-05-04), and development continues in the official Highcharts repo. This means it can be loaded from code.highcharts.com and is available with the Highcharts npm package. Issues should now be reported in the Highcharts repo.
