The following new feature was deployed today:
Graph Hover Lock
When you hover over a graph with multiple datapoints, with your cursor close to one datapoint, that datapoint is highlighted. Now it's highlighted more prominently and brought to the front, while other data points fade to the back.
You can also click the graph to lock that state into place. You can tell it's in a locked hover state by the lock icon in the upper right corner of the graph. Click the graph again to unlock.
For graphs with many datapoints, this will help you zero in on the specific datapoint(s) you want to focus on.
See Figure 1. A number of the data points are hard to see because of the number data points in the graph.
Hovering over the graph allows us to view the datapoints more easily. Here in Figure 2, we have used this feature to lock the graph and now we ca can see one of the smaller datapoints clearly.
To enable this behavior across all graphs, a couple click behaviors have changed. First, when on the graphs list page or on a worksheet, you can no longer click a graph to go view that graph; now you have to click a graph's title bar to go view it. Second, on the metrics page in grid mode, you can no longer click a metric graph to select that metric for graph creation; instead, you have to click the metric graph's title bar.
