manually creating data for plotting?

This was a response to a question I had on another thread (http://forums.indigodomo.com/viewtopic.php?f=219&t=18579)

You could do the extra data feature in indigoplotd. But you have to create the data yourself, create a file:
x;y
Date1;value1
Date2;value2
...
Then create a plot device and select data from external file then select that data in the line def section.

you also need to set the data format in the frame section

That should do it.


Which Karl solved in a different, easier manner.

But is there a wiki or thread that explains how to do the above? I am now trying to generate a plot of some predicted weather-- that is, pulling down current predictions for day+1, day+2, etc. rather than past measured data, as one would typically plot.

I think the way to do this is to use the "extra data from file" feature of the plugin, and manually define the x axis. But I don't know how to create the data in the database.

Thanks.

Re: manually creating data for plotting?

It depends on your source.
Read the data
Add a line to a file for July 3 temp =90
20170703000000;90;
If you know how to do that you can do the next steps. (Which Filename, ... use in indigoplotd...)
I can post something later this week. Still out of town.
