1. Scatter Plot: Distribution of Chemical Values in Past Years and Recent Years Since we want to show the trend of past years and recent years, we therefore define years before 2013 as Past, years after 2013 as Recent. Moreover, map out the color to better disdinguish these two situation. User can choose the chemicals by using the drop down menu.
2. Heat Map: Number of Records of Different Location by Year Location arranged by different streams. The darker the color, the higher the value.
3. Heat Map: Number of Records of Different weekdays All records from 1998 to 2016, arranged by month and weekdays. The darker the color, the higher the value.
4. Boxplot: Distribution of Chemical Value (Quarterly) Only years from 2013 to 2016 are used. Filter for different streams and chemical measurements. Grey line shows the trend line for each pane. Color mapped by different streams.
5. Control Chart: Distribution of Chemical Values by Location (1 std) Formulas for upper bound, lower bound and Outliers. Lowerbound: WINDOW_AVG(SUM([Value])) - (WINDOW_STDEV(SUM([Value])) * 1) Upperbound: WINDOW_AVG(SUM([Value])) + (WINDOW_STDEV(SUM([Value])) * 1) Outliers: SUM([Value]) < [Lower Bound] OR SUM([Value]) > [Upper Bound] Map outliers to color, blue means this value exceeds Upperbound or Lowerbound. Filter based on streams.
6. Map: Map of Value on Selected Chemical Measurement By changing the different chemical from boxplot, the map will keep changing. The color mapped out by different streams. the circle represent the value of this location, the bigger the circle, the higher the value. Hover on the location point, the tooltip will show the distribution of the selected chemical at this location.
