Customization: - "graphWidth" and "graphWidth" can be defined for the image size - "showLegend" can be defined to show or hide the legend of the graph - "subject" can be defined for a customized subject for the mail message - "periods" and "periods_headers" can be defined for displaying multiple periods of the same graph, or - "period" and "period_header" can be defined to display a single graph The html.template and plain.template files can be adjusted (TWIG format).
