What is the trend thing in the Weight Log?

I just added a new weight again, and I was wondering what the trend is supposed to mean?

It lists the date, weight, trend...

I clicked on the "Question Mark" and found this.

Tracking your body weight gives you a clear illustration of where you are in your weight loss journey, and it also depicts this journey's direction better that you would be able to with just a pen and paper. Namely, our weight graph includes a trendline (green line), which averages out the daily fluctuations in your water weight and uncovers your true weight loss progress.

For people who weigh themselves frequently (i.e. daily), the trend line is supposed to show the overall direction of weight loss, regardless of daily up / down fluctuations.   For people who weigh weekly, or less frequently, it doesn't seem to be much use - so feel free to disregard it.

I weigh about weekly - thanks for the answers!
