We have just released v1.9.6 Beta with Methods & Properties, which allows you to programmatically export chart as image, print chart, access internally calculated values, etc. Please refer to the release blog for more information.
You can hide ‘save as PNG’ using CSS. Here is an example.
You can also have a button/link outside chart to export it as JPEG, using dataURL. Here is an example.
Thanks Vishwas for the examples. The hide option works fine. The button/link outside the chart also works fine on a PC running chrome 49. But when i try running it on my android Samsung galaxy note 5 the filename “chart.jpg” is relpaced by the filename of the html document that i execute in chrome. It saves an exact copy of the executing html file when the ‘Download’ link is pressed. Please help. The mobile is also running chrome 49.0.2623.105 on Android 5.1.1.
Strangely the Export tab on the right top works fine and saves a jpeg image. Even the example in the fiddle runs fine on the mobile.
