  title: Matomo Reporting API for plugin Image Graph API
  version: 1.0.0
  description: 'The ImageGraph.get API call lets you generate beautiful static PNG Graphs for any existing Matomo report. Supported graph types are: line plot, 2D/3D pie chart and vertical bar chart.  A few notes about some of the parameters available:<br/> - $graphType defines the type of graph plotted, accepted values are: ''evolution'', ''verticalBar'', ''pie'' and ''3dPie''<br/> - $colors accepts a comma delimited list of colors that will overwrite the default Matomo colors <br/> - you can also customize the width, height, font size, metric being plotted (in case the data contains multiple columns/metrics).  See also <a href=''https://developer.matomo.org/api-reference/reporting-api-metadata#static-image-graphs''>How to embed static Image Graphs?</a> for more information.'
