The following visualizations provide some historic context since upstream investment (source: IEA) is one of the key factors affecting membership at the macro level.

Instructions:

Resizing:
The graph is designed to fill the entire width of your browser's window. It will resize when you expand or shrink your browser window. If you change the window size while the graph is animated, the blue, visible plot area will not change so you will need to resize the window again after the animation is finished.

Values:
You can find the values at any point on the graph by hovering your pointer over that location.

Date Ranges:
The date range of the plot can be adjusted either using the pre-configured ranges at the top left of the graph or by selecting a custom range using the slider at the bottom of the graph.

Toggling Plot Visibility:
By clicking on the items in the legend you can turn on and off the various lines on the graph.

Tools:
There is a tools menu at the upper right of the graph which is visible when you move your cursor to that area. With these you can capture an image of the graph, zoom (in, out, or continuously), pan, autoscale the axes for a single plot, reset the axes to the original values, turn on/off spike lines, turn on/off hover information and compare hover information.
