Example

Here is an example of how to call this API.

Request

{
"value" : "base-64 chart image string"
}

Usage

You can display the base-64 string inside an HTML image tag: <img src="data:image/png;base64,{base-64 chart image string}/>.

For default behavior, use Image(width=0,height=0,fittingMode='fit'). Here is an example of a chart image returned with the default parameters.

If you want to customize the display of the image, specify a height, width, and a fitting mode. Here is what the same chart image looks like if you retrieve it with these parameters: Image(width=500,height=500,fittingMode='Fill').
