The controls contain a filter that lets users choose the display of the x-axis. Users can view the x-axis data by study day, visit number , or visit. The default is to display the x-axis by study day. The x-axis displays the point in time in which the data is collected and manipulating it changes the scale at which the data is plotted.
Users can view how many participants fall within the normal range for a measure by observing the small, green box to the bottom-left of each chart. This box contains an integer that corresponds to the number of subjects that fall within the normal range and are excluded from that chart on initial load. When the normal range method changes or is set to "None" the count in the box will change to reflect the new number of participants with inlier data. When there are no participants to display, the box will disappear. The box will reappear when the normal range is manipulated and participants fall within the normal ranges again.
Participants with data that fall within a normal range for a measure are hidden by default. Users can select the checkbox to view inlier participants. Selecting to view inliers will render their data in each chart and will remove the inlier count to the left of the chart. Selecting to hide inliers will remove the inlier data from each chart and will show the inlier count to the left of each chart.
Users can opt to change the method for the normal ranges to the following options: None, LLN-ULN, Standard Deviation, and Quantiles. The default for the normal range controls is set to "LLN-ULN", which is the upper and lower normal range specified in the data. Users may select "None", which will remove the green shading around the normal ranges and will remove the inlier count to the left of the charts. Users may also select "Standard Deviation", which will prompt the user to enter the number of standard deviations they would like to set as the normal range. Altering the default value will change the upper and lower normal range bands in the chart and will change the inlier count to the left of the chart. Users may also select "Quantiles", which prompts the user to enter an upper and lower quantile to set as the normal ranges. Altering the upper quantile will change the upper normal range band in the chart and altering the lower quantile will change the lower normal range band in the chart. Changing the normal ranges may change the number of inliers and the inlier count to the left of the chart will update based on your selections.
Users can select the checkbox to view visits that do not contain data. Checking the box will show a timepoint for the visit. Unchecking the checkbox will hide the timepoint for visits without data; visits without data are hidden on default.
Users can select the checkbox to view data that is not associated with a scheduled visit. Checking the box will show a timepoint for the unscheduled visit and its associated data. Unselecting the checkbox will hide the unscheduled visit timepoint and its data; unscheduled visits are hidden on default.
The Paneled Outlier Explorer gives users the option to add custom filters. Users can specify a variable they would like to filter by within the settings object, and the chart will allow users to filter by that variable. This option allows further customization and additional filters do not appear by default unless a user or project team requests them.
This menu is used to filter the lab variable that is displayed in the chart. The default measure is set to display all variables in the data set, but users can uncheck the "Measures" box to remove all measures and their associated charts from view. Users can also use the check boxes to select or unselect any individual pre-defined measure in this filter. Checking a measure's box will display a chart associated with that measure. Unchecking a measure's box will remove its associated chart from view.
A title will appear at the top of each chart for all measures in view. The title contains the name of the measure, its short name (if applicable), and the units it is measured in.
When users hover over a chart a "+" button displays to the right of the chart's title, which allows users to enlarge the chart. Charts are automatically rendered in a smaller uniform size, but users may opt to make them larger to see the chart in more detail. Once a chart has been enlarged, users can select the "-" button to return the chart to its original size.
When users hover over a chart, an "x" button appears, but the option will disappear once users move the mouse off of a chart. Clicking the button will hide the chart from view and unselect its box from the controls menu. Users much reselect it in the controls menu to view it again.
This feature highlights the normal ranges for a measure by displaying a green rectangle behind the data. This rectangle represents the normal range for each measure and data that falls within the upper and lower limits of the range contains records of participants who are associated with results that are considered normal.
Clicking an area and dragging the mouse to encompass a data point will highlight the selected point using an orange line. The selected data point will be highlighted in all of the measure charts in view and in the data listing. When a user clicks outside of the selected data point, the orange line disappears along with the detailed listing.
The data listing tab takes the user to another screen to view the underlying data records in the paneled outlier explorer.
If the data doesn't fit on the initial page, then pagination options appear at the bottom right corner. Each page defaults to show 10 records, so the pagination allows users to explore more data records than what is presented on the default page. This feature can be turned on/off by configuring the chart settings.
The detailed view allows the user to search for a specific term to locate it in the data. To initiate this feature, users can type text into the box and the entry automatically searches through the data listing and displays results with matching text. The number of records displayed is shown to the right of the search box. To return to the default data display, the user can click in the search box and delete the entered text. The search feature can be turned on/off by configuring the chart settings.
Users can click on a column header and sort the data within a column in ascending and descending order. The first time a user clicks the column header, the column is sorted in ascending order and a box appears above the data listing containing the variable name that has been selected and an arrow indicating the direction of the ordered data. When a user clicks the column header a second time, the data will be sorted in descending order and the direction of the arrow in the box above the data listing will change to match the new sort. Clicking on the red 'x' within the box containing the variable name both removes the sorting and closes the box. The sort feature can be turned on/off by configuring the chart settings.
Users can download the data as a CSV by clicking on the 'CSV' button located underneath the chart within the detailed view. The CSV file will contain all of the data if no filters have been utilized. If filters have been used, the CSV file will contain the resulting data. The file will also capture any sorting that has been initialized in the data. The CSV download will be named using the following convention: webchartsTableExport, date, and time. This feature can be turned on/off by configuring the chart settings.
