    Hi,

    First of all – I really like this plugin. In time it will be one of the core components of my site “Turglede” where kayak paddlers can share GPX tracks.

    Three things:

    1) I cannot get the graph to show the speed. (It might be the GPX files’ fault?)

    2) I cannot remove “altitude” from the graph. (It is not really interesting for kayak paddlers).

    3) If I cannot get speed to show I might consider removing the graph all together just keeping the map and the summary. Is that possible?

    GPX file: http://www.turglede.org/filetransfer/haaoya.gpx

    The relevant post on the web-site: http://turglede.org/2013/04/02/rute-haoya-20130401/

    Thanks

    /Mich

    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

    Huff… thought my Garmin took care of those entries.

    I will look around in my files and see if I can do anything about it.

    Thank you very much for your help! 🙂
