Working in celcius

[gorstj]

Trying to decode the index.html to find the setting for changing the y axis so it is a sensible range for degrees celcius - any ideas?

I actually don't remember because I haven't looked at this code since I first commited it. ;-)

However, I believe the y-axis automatically adjusts to the range of data points. The hackish thing I did was map the "heat on/off" line to 60 and 61 degrees so it could appear on the same axis. So I bet if you change the line:

return { date: d.date, val: +d[name] + 60 }

to:

return { date: d.date, val: +d[name] + 15 }

Or some value that's within the range of your Celsius values, it might solve the problem. No guarantees; I can barely understand the D3 code any more at this point.

Thanks for your suggestion. Here is what I did to get it looking reasonable for us new UK Nest customers who like degrees celsius:

Change line 156. I have changed 60 to 0. When heating is on there is a line at 1 degrees, when off the line is at 0 degrees. Make sure that the temp range you list in the next section includes these values.

line 156:

      return { date: d.date, val: +d[name] + 0 };

Change lines 170-173. Change 0, 30 for the temp range you want, using the 'auto' settings I commented out it would miss out my target temperature graph which is lower than any of my away temperatures currently. I have commented out the lines that are now redundant, you can delete them:

lines 170-173:

  y.domain([0, 30]);
//      +d3.min(points, function(c) { return d3.min(c.values, function(v) { return v.val }); }),
//      +d3.max(points, function(c) { return d3.max(c.values, function(v) { return v.val }); }) + 0.5
//  ]);

line 191:

    .text("Temperature (C)");
