Site Navigation
Navigation through this site is generally accomplished in two ways. The menu at the
top of the window (just below the black "Envision Big Wood Basin" banner) let's you
jump to specific locations in the site. Some of these menus have an additional "drop-down"
menu providing additional navigation options. For example, clicking on the "Storylines"
menu item brings up an additional drop-down menu that let's you navigate to each individual
storyline. Additionally, at the top and bottom of each screen are a set of "Previous"
and "Next" links - theses take you the the preceeding and next page in the site.
Also note that clicking on many of the images on the site will bring up a larger,
higher resolution version of the image in a new browser window. Close this
window to return to the orginal page.
Working with The Charts
This site contains numerous charts, maps, and other types of graphics. Many
of these, the charts in particular, are interactive. "Hovering" your mouse/pointing
device of the chart allows you to see the underlying data for the point(s) at the
location you are hovering. Also, because of the large amount of data used
in these analyses, the charts can initially be somewhat intimidating to interpret.
To allow you to focus in only those datasets you really want to see in the charts,
we have provided a number of filters that you can interactively turn on anf off to show only those subsets of the data
you find useful.
Try it out - we've provided a sample chart below you can use to try out some of the interactive
chart features.
- Most charts have predefined filters buttons for filtering the data by specific climate
and/or management scenarios.
- Clicking the "shortcut" buttons at the bottom of the chart filter the chart display
by the text indicated on the buttons. You can further filter the data displayed on
the chart by entering a search string in the "Filter" box near the bottom of the chart.
- All Charts also have a "Filter" text box that you can type a filter string into. This is an extremely helpful feature for the more complex charts
with many data series. Whatever you type in the filter box will be compared
to the legend text; only those dataseries which contain the filter text will be displayed
on the chart. Multiple filter terms can be specified; separate this terms with a space. To
filter by excluding terms, prefix the filter term with a negative (-) sign.
- You can "turn on" or "turn off" as specific data series on the chart by clicking on
the legend categories for that data series.
- "Double-clicking" on the legend category will turn "on" the corresponding data series
while turning off all the other series.
- Clicking the "Reset" button will remove all filters and reset the chart to its original
state.

Interpreting the Cascade Plots
|
Many results are displayed as a set of charts, like the one shown below. We use the
example plot shown here to explain the symbology in these plots. This example
is a plot of basin-wide average temperatures with a focus on the Reference Case scenario.
-
The cascade plot in the upper left shows results for every day of the simulation.
The color intensity in this image corresponds to value -- in this case higher temperature
is indicated with more intense color.
-
The box and whisker plots in the center right show decadal trends. In this
case for temperature for the Reference Case scenario.
-
The plot at the far right shows annual averages or totals, in this case the average
annual temperature for the basin. The dark line in the plot shows the trend
for the Reference Case scenario. The blue shading in this plot indicates
the range of results for the four simulations that varied the exogenous drivers of
climate and population. In this case, since population has no effect on
temperature, the shading indicates the range of results for the three climate scenarios.
This plot indicates that by 2100, basin-wide average annual temperature will increase
between <1 degree Celcius and 5 degrees Celcius.
-
The plot at the bottom shows the daily values averaged for early, middle and late
in the century. As in the plot on the far right (see above) the blue shading
indicates the range of results for the four simulations that varied the exogenous
drivers of climate and population. In this case, since population has no
effect on temperature, the shading indicates the range of results for the three climate
scenarios. For example, the plot indicates that late in the century, average
summer temperatures peak at about 24 degrees in the Reference Case scenario.
The blue shading indicates that in the High Climate Scenario that average temperature
for late century was even higher -- about 27 degrees.
