Hi Michael, the plugin cannot show the speed because your gpx has neither speed data nor datetime values..
this is your gpx values:
<trkpt lat=”59.674811857″ lon=”10.621763282″>
<ele>-4.669312</ele>
</trkpt>
<trkpt lat=”59.674815042″ lon=”10.621772334″>
<ele>2.540649</ele>
</trkpt>
and this is a normal gpx:
<trkpt lat=”47.179443333″ lon=”-1.573975000″>
<ele>134.437900</ele>
<time>2011-09-25T18:04:55Z</time>
<speed>2.884012</speed>
</trkpt>
<trkpt lat=”47.179463333″ lon=”-1.573978333″>
<ele>134.438500</ele>
<time>2011-09-25T18:04:56Z</time>
<speed>2.240630</speed>
</trkpt>
<speed> and <time> values might be removed from GpsBabel in order to reduce the gpx size..
To remove the the chart you can set gheight=0 in the shortcode
