“Amending” as in showing other data? That is not the easiest job, I’m afraid. Data has to be preprocessed in an array and fed to the HighCharts API.
Debugging can be a problem. When the series data is different from what HC expects, everything just breaks and no chart is shown. But I am no HC expert, so maybe that is just my problem 🙂
OK- another one for the future.
I’m quite pleased with the standard charts, there’s just a few additional features I would like to include.
And probably change some of the wording and headings.
Most – if not all – texts in the plugin (also in the charts) can be changed via the translation file.
