This plugin generates charts from GPX-files. The file will be processed in real-time, no intermediate data is written to the database or the wp-content directory. Currently the plugin is tested with GPX-Files generated by a Garmin-Device. The TRK-Section is parsed and information about your heartrate, your cadence and the current speed is calculated. Since GPX-files can contain a lot of data-points they can be reduced to a certain amount to guarantee, that the rendering time of the chart won’t consume to much time in your browser. You can hover with the mouse over the generated chart to get detailed information about the currently selected time-instance. You can also turn off graphs that where currently shown. Every graph get its own Y-axis and color.
