How to Use This Tool

This is a draft, beta, HTML5 version of the Great Lakes Dashboard. Because of the technical restraints of web programming, this dashboard has fewer capabilities than the Flash based dashboard (but you can still do quite a bit). Some pointers below:

  • For this dashboard there are 2 tabs labeled 'Variable' and 'By Basin'. The 'Variable' tab allows you to look at data from all lakes for a single variable type (see next bullet on variable types). The 'By Basin' tab allows you to look at multiple variables' data for a single lake. For both modes, there's a drop down menu in the top right region of the chart area to change the variable or target basin.
  • The right hand side has the data menu which you can hide with the '>>' button directly above it. It is a hierarchical, accordion menu, with the levels listed below:
    • Variable (or Axis): 6 currently available (all caps, bold, underlined)
    • Primary Category (underlined, bold)
    • Secondary Category (bold)
    • Data Series ID (normal font)
    Thus, if you are looking at a single variable, such as water levels, you'll want to click on 'WATER LEVELS' to view the available data for that variable.
  • The time slider component is at the bottom of the screen. Click and drag one of the tabs to adjust the visible time range of data. A box indicating your desired range of years will appear over your pointer.
  • To change the visible units between Metric and Imperial, click the 'Metric'/'Imperial' button above the data menu. That button's current label indicates the current type of units displayed on the charts.
  • To view exactly what units are used for the data, hover over or touch the data points to view a data tip.
