I would like to know if it is possible to save a chart as an image. I read on one answer that there should be the option "Save as an image" when right-clicking on the chart, however I don't find it.
Could anyone please tell me if there is an alternative to the snapshot?
If you're using the FlashChart module, then there will be a right-click option that says "save as image". However if you're using the default Splunk search page or one of the reporting pages or a dashboard that you created, it will be using the JSChart module instead. As far as I know the JSChart module doesn't implement the same feature.
So if it's already an Advanced XML view you could clone the view in question and swap out JSChart for FlashChart. And on the other hand if it's a simplified XML view you'll have to convert it to Advanced XML first.
