User defined metrics, is there documentation ?

[Thin Lenny]

Hi,

I woud like to add a metric that give time spent between two fixed power values, ie : [100,200]

I've created à user defined metrics like that :

{

# only calculate for rides containing power

relevant { Data contains "P"; }

# initialise aggregating variables

init { seconds <- 10; }

sample {

if (POWER > 100 and POWER < 200) {

seconds <- seconds + RECINTSECS;

}

}

# calculate metric value at end

value { seconds / 60; }

}

Type = sum

But it give me a flat chart in the trends after creating a new one for this metric.

Can you help me ?

Another question, what is the use of conversion factor, conversion sum and the test button ?

Thanks :-)

It's && instead of and, look at: https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Formula-Syntax-and-Expressions

Test button is to test your metric on the selected activity, conversion factor and sum are used to convert from metric to imperial units

Thank you for your answer.

I've found the main problem : if I remove this line :

relevant { Data contains "P"; }

I get the right computed result, otherwise I get 0

What is wrong with this ?

It will only bother to compute the metric if power is present in the file.

The "Data" metadata field contains a letter for each data series that is present.

P=Power

H=Heartrate etc

I should describe this in the wiki, will fix it now.
