moving average not displaying?

[hjf]

Hi everyone.
I have a graph that shows the temperatures of a sensor located outside my house. It sends the temperature at regular intervals, so I have a TimeSeries and a TimeSeriesCollection.

Every second it does this:

Code: Select all

chartdataset.add(actual, temperatura);

so the new temperature is loaded an the graph is automagically updated. The problem is that I tried to add a moving average. But that is not showing. The legend says " -- Moving average" (in a different color), but it doesn't actually draw the line.

Every time I add a new temperature I also do this:

Code: Select all

tmpMovingAverage.add(actual, temperatura);

I even made

Code: Select all

temperatura=Math.random()*100;

so the data will have a big span, but even then the blue line doesnt show.

What am I doing wrong?

Cheers!

Well I checked with some random data, and the line is showing, just not updating. (I loaded it with data, the first few points show, but new data is not shown).

Anyone?
