I'm using the Visualization API to display charts on a web page, but now I have to also produce a PDF of those charts, so I'm switching to using the regular Chart API so I can capture the URL being POSTed and grab the image that way. One problem I've run into is that they're not the same, or don't produce the same results.
For example, the Visualization API can display data numbers right on the Pie chart itself, whereas, as far as I can tell (and read), the Chart API doesn't. Are there any plans on adding this feature to the Chart API? Right now it seems only some charts can have data numbers displayed on them, and Pie chart isn't one of them. Having said that, has anyone come up with a way to either a) add data labels onto a Pie chart (and not appended to the legend labels), or alternatively b) figured out a way to capture the Visualization API's data and have that available to use? I'm using PHP to generate the PDF file, and all I have to do is grab the API's URL and use it: $imgURL = 'https://chart.googleapis.com/chart?cht=p&chs=..."; $pdf = new myPDF(); $pdf->image($imgURL, $x, $y, $absx, $absy, 'PNG', ''); If I knew what the Visualization API was using as URL to get the images, I'd use that.
