Because administrators can configure and style their reports, the functionality and shades described in the sections below may differ.
The title of the report normally appears at the very top. It typically lists the name of the theme, indicator and time period being displayed. It may also display any filter that you have applied to the data.
Data Button: Click this button to display the available theme(s), indicator(s) and time period(s) in the Data Explorer.
Geography Button: Click this button to display the available geographies for the base geography.
Filter Button: Click this button to display the available filters in the Filter Explorer. If there are no filters in the report this button will not be available.
Help Button: Click this button to access a help document.
Notes Button: Click this button to link to external documents or websites with further information for the selected indicator.
The administrator may have added further buttons to the report you are viewing.
All components of the report have a small toolbar that becomes visible when you hover over the top right corner of the component (unless the administrator has disabled this). There are thee buttons available that allow the user to drag the component to another place within the report, to maximise the component to full screen and then restore it again to its original size and location or to close the component so that it disappears from the report. The components can also be resized using the little arrows that appear when you hover over the border or corner of the component. To restore the layout to its default upon load of the report, right-click anywhere in the screen and choose 'Reset Layout' from the context menu.
The Data Explorer lists the available themes, indicators and time periods. Click theme and indicator names to expand or collapse them. Click a time period or an indicator without a time period to load new data.
Click '+' button in the bottom right corner of the Data Explorer to expand the available theme(s), indicator(s) and time period(s).
Click '-' button in the bottom right corner of the Data Explorer to collapse the available theme(s), indicator(s) and time period(s).
The Filter Explorer lists any available filters and their values. Click filter names to expand or collapse them. Clicking a filter value will filter the report so that only geographic features with the selected filter value are prominent. The administrator may have configured the report so that the map zooms to the filtered area. If this is the case you should use the "Zoom Full" button in the map toolbar to return to the original map extent.
Select features: Click the name of a geographic feature to select the feature. A selected geographic feature will be shaded orange. Alternatively, hold 'Ctrl' to select multiple features or 'Shift' to select a range of features. Holding the 'Ctrl' key and clicking on a selected feature allows you to deselect it.
Adjust column width: Hold your mouse pointer over the divider between column headers and lateral arrows will appear. Click and drag the divider to adjust column width.
Change column order: Click a column header and drag it to change the location of this column within the Data Table. E.g. if you want the notes icons to appear right of the data colums you can simply drag the whole column with the nots icons to the right border of the data table.
Sort Columns: Click a column header to sort the table ascending/descending. Note that the Name column and the Indicator column of categoric indicators will sort alphabetically while the Indicator column of numeric indicators will sort numerically. Associate values (typically shown in columns to the right of indicator values) always sort as if they were text unless the administrator has defined otherwise.
Magnifying Glass Icons: Click the magnifying glass icons to make the map zoom to individual geographic features.
Notes Icons: Click these icons to link to external resources.
Legend Colours: Small circles shaded in the colour of the class which the data value of this area is within in the legend. This helps to get a better visual impression of the data.
Scroll: A vertical scroll bar will be available if data cannot be viewed within the table dimensions.
Shading: Geographic features are shaded based on values in the data table according to the map legend.
Zooming: Use the slider bar on the left of the map to zoom in and out. Click the zoom full icon (bottom magnifying glass) to zoom back to full extent. Alternatively, hold 'Shift' and click and drag a box on the map. The map will zoom to the area within the box drawn. You can also use the scroll wheel on your mouse to zoom in and out of the map
Area Selection: 'Ctrl' and click and drag a box on the map. The map features within the box drawn will become selected.
Select a Geographic Feature: Click on a geographic feature to select that feature. A selected geographic feature will be shaded orange. Hold down 'Ctrl' key to select multiple map features.
Tooltip: Hold your mouse pointer over a map feature to display a tooltip with the geographic feature name and value.
Bars: For numeric indicator values there is a bar representing each geographic feature listed in the data table. The height of the bars is proportional to the values in the data tabel. Bars are displayed in the same order as the features are sorted in the data table and shading is linked to the legend.
Select a Geographic Feature: Click a bar to select the corresponding geographic feature. A selected bar will be shaded orange. Alternatively, hold 'Ctrl' to select multiple bars or 'Shift' to select a range of bars. You can also drag a box to select multiple bars on the chart. Holding the 'Ctrl' key and clicking on a selected bar allows you to deselect it.
Error Bars: The bar chart may display error bars representing the lower and upper confidence limits associated with indicator values. These give an indication of whether the differences between indicator values are statistically significant.
Comparison Values: The bar chart can display values for comparison geographies as well as features in the base geography. Values for comparison geographies are shown using a horizontal line across the chart.
Tooltip: Hold your mouse pointer over a bar to display a tooltip with the geographic feature name and value. It might also show the lower and upper confidence limit values of error bars.
Slices: The number of slices and shading is linked to the legend. The size of each slice is proportional to the number of geographic features in the corresponding category.
Select a slice: Click a slice to select the corresponding geographic features. A selected slice will be seperate from the pie.
Tooltip: Hold your mouse over a slice to display a tooltip with the name of the category and the proportion of geographic features in this category.
Trends: The time series chart shows change in indicator values over time. Hold your mouse over a geographic feature in the map, data table or bar chart to view a trend in the time series chart. Click a feature in the map, data table or bar chart to select it and freeze the trend in the time series chart. Hold your mouse pointer over the points for any frozen trend in the time series chart to display a tooltip with geographic feature name, the time period and value.
Comparison Trends: The time series chart may display trends for comparison geographies.
Tooltip: Hold your mouse pointer over the points of a trend line for any geography in the time series chart to display a tooltip with the feature name, the time period and value for the comparison geography.
Legend: The legend is displayed in the map layers list. It can be controlled by clicking on the 'pencil' icon next to the base geography name in this list. This will open the Legend Settings dialogue box.
Legend Settings: The items available in the Legend Settings dialog may vary depending on the data in the report and the way the report has been configured.
Border colour: The colour of the border around each geographical feature on the map.
Transparency: By sliding the bar the transparency of the shaded features in the map can be altered.
Palette: You can change the color palette used to shade geographic features in the map by clicking on a new palette.
Reverse Palette: By checking this box you can reverse the color palette used to shade geographic features in the map.
No. Classes: You can increase or decrease the number of classes by clicking the Increase or Decrease buttons (labeled with black arrows). The administrator may have fixed the maximum number of classes.
Classifiers: Select a classifier from the drop-down. This will decide how the ranges are calculated.
Equal Interval: The intervals between class breaks are equal. Class breaks are calculated on-the-fly and will update if you change the number of classes. Geographic features in the same class are given the same shade. The administrator may have configured the report so that the class breaks are the same across all indicators in the report. The advantage of the equal-interval classification is that many map users will find it simple to understand. However, a disadvantage is that only the minimum and maximum data values are used when determining class breaks for the intervals (rather than the way the data is spread).
Quantile: Each class in the legend contains an approximately equal number of geographic features. Class breaks are calculated on-the-fly and will update if you change the number of classes. Geographic features in the same class are given the same shade. Two advantages of the quantile classification are that it is appropriate for ordinal data (as data are rank-ordered) and that it can help make map comparisons (assuming that the same number of classifications is used for all maps). A disadvantage of the quantile classification is that it does not consider how the data are distributed. If the data distribution is highly skewed, data observations will be forced into the same class (either the lowest or highest) where this may not be appropriate. As a result, the quantile classification may give a false impression that there is a relatively normal data distribution.
Natural Breaks: This classification method is also known as Optimal Breaks and Jenks’ Method. Class breaks are calculated on-the-fly and will update if you change the number of classes. Data are assigned to classes based upon their position along the data distribution relative to all other data values. An iterative algorithm is used to assign values to classes such that the variances within all classes are minimized whereas the variances among classes are maximized. The advantage of this classification is that the data distribution is explicitly considered for determining class breaks. However, the disadvantage is that map users may not understand the classification method used and that class breaks may not be immediately intuitive.
Continuous: Each geographic feature is shaded a different shade using a continuous scale. This legend type is useful for identifying extremely high or low values. Where an indicator has only a small number of unique data values (say 5 or less) this may be the most appropriate legend type to apply.
Standard Deviation: Class breaks reflect the number of standard deviations from the data average (or mean). Geographic features are classified according to how many standard deviations above or below the average their indicator value falls. Geographic features in the same class are given the same shade. You cannot change the number of classes for this legend type.
Min Point Size: If the data in your dynamic report is being displayed as proportional symbols (points), then you can set the size of the smallest point(s) here.
Max Point Size: If the data in your dynamic report is being displayed as proportional symbols (points), then you can set the size of the largest point(s) here.
Highlighting and Selecting: Hold your mouse pointer over a class in the legend to highlight the geographic features that fall into that class. Click a class to select the geographic features that fall within that class.
Click the check boxes to toggle the base geography on / off. Contextual geographies and background images may have been included by the administrator and can also be toggled on or off using the check boxes in the map layers box. Background images are "scale dependent" - they may turn on or off as you zoom into or out of the map. Note that images may not be visible at full map extent and you may need to zoom to a smaller area for them to appear. Depending on how the report has been configured, it may take some time for background images to appear.
This table lists any comparison geographies that have been included in the report. The administrator may have configured the report so that comparison values are displayed in charts when you hold your mouse pointer over a comparison geography name.
The Time Animation component can be used to visualise indicator data over time. You can click on the bar to change the date that is currently displayed in the dynamic report components. You can also use the left and right arrow symbols to step through each date, or click the triangle/play symbol to cycle through all the available dates for the currently selected indicator.
The scatter plot displays the relationship between data for two different indicators or time periods. Read the axis labels to see which data are being plotted. Hold your mouse pointer over a dot in the scatter plot to display a tooltip with the name and values of the geographic feature it relates to. The administrator may have configured the report to display a correlation coefficient, line of best fit and an equation for this line. The correlation coefficient is Person's Product Moment Coefficient and this statistic is underpinned by certain assumptions about the data.
The spine chart displays cross-indicator information (i.e. a profile) for any selected area(s). Select a geographic feature in the map, data table or bar chart of your report to make it appear in the spine chart. Hold down the 'Ctrl' key and select futher geographic features to show multiple areas in the spine chart. The administrator may have disable the mulitple selection of areas. Alternatively you can select a section of the pie chart to select the geographic areas which are within the corresponding category which will subsequently appear in the spine chart. The selected area(s) will be shaded orange and the geographic feature name(s) will be displayed in the spine chart. This column may have been renamed by the administrator.
The horizontal bars will show in a different colour for each different geographic feature. By default, the horizontal bars are proportional to either the '% diff' values or the indicator values for the selected area(s). However, the administrator may have configured the report so that the bars are proportional to alternative values. For each indicator, the minimum and maximum values are shown at either side of each bar. For each horizontal bar, a target can be shown as a vertical bar. The column with bars may include coloured ranges - you can quickly see how an area is performing by seeing which range its horizontal bar extends into. The key for the coloured ranges is shown at the foot of the chart. For each horizontal bar, one or more targets may be shown as a vertical bar or an alternative symbol. You can scroll the chart to see indicators that are listed further up or down. By clicking on a row in the spine chart you may be able to change the theme and indicator that are being shown in the map, bar chart and pie chart. At the bottom of the spine chart you will find a '-' and a '+' button. These will collapse and expand the themes in the spine chart respectively.
