Regardless of the plugin used, you can easily export the end result as an image, such as a graph, chart, price table, bracket, etc.
To export your chart as an image, from your plugin editor, click Export, then Export to image.
You can specify the width of your chart as you like. It is recommended however to keep it above 700 so that the data is clearly visible.
You will receive an Exporting chart notification that the download is in progress.
Once downloaded, here is how the chart will look like:
Hope that was easy enough for you :)
