I am building a web application with grails and using the jxl API to generate an excel file to allow formatting. I would like to generate a chart using data in my application to include with the excel file.

The only source I have found to create a static image that could be saved and then inserted into the excel file is the deprecated Google image charts API to build a URL string to retrieve the corresponding chart.

  1. Should I be concerned about doing this with the deprecated google image charts, or should I be fine, given that I am only using the pie chart type?

  2. Should I be going about this entirely different? Using the browser to save the image could be problematic because the app needs to support ie. 7-9.

Thanks

    I would worry that Google would just remove the service after 2015; it might not matter that it’s just a simple pie chart if the remove the service completely. I don’t know the likelihood of that happening, but could be a concern.

    You could use the JFreeChart API to generate the chart as a png and the use jxl to insert it into the spreadseet using sheet.addImage().

    There is an example of creating the chart using Grails here
