Using Maps
How to use the maps?
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. Buttons
Data Button: Click this button to display the available theme(s), indicator(s) and time period(s) in the Data Explorer.
Filter Button: Click this button to display the regions.
Help Button: Click this button to access a help document.
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 notes icons to the right border of the data table.
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.
Menu: Click on the little triangle in the map toolbar to open a menu with further options for the report. These are also available via the context menu (right click mouse button) and are explained in detail in the section Context Menu
Area Selection: 'Ctrl' and click and drag a box on the map. The map features within the box drawn will become selected.
Bar Chart
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.
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. Box-and-Whisker Chart
Pie Chart
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.
Legend
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.
Time Animation
The time animation component can be used to view how indicators change over time. You can click on the bar to change the date that is currently displayed. You can also use the left and right arrow buttons to step through each date, or click the "play" (triangle) button to cycle through all the available dates for the currently selected indicator. You can pause the animation by clicking on the pause button.
Printing
Print Preview: This option allows you to print either the full InstantAtlas dynamic report or individual components of the report. You can also decide if you want to print the dynamic report in Vector or Bitmap format. If you want any layers to have transparency (e.g. if you have background mapping switched on) you should choose to print in Bitmap format. If you do not require transparency of you may choose the Vector format which provies best quality.
You have the options to have the buttons within the InstantAtlas dynamic report showing in your printed output. You can also choose to have the images and the background appear in the printed output by checking or unchecking the respective boxes.
Export: This option allows you to export the full InstantAtlas dynamic report or individual components of the report in either JPEG or PNG format.
Reset Layout: This option allows you to return to the original layout of the InstantAtlas dynamic report.
Add Text: This option opens a text editor window that allows you to add custom text to the report. Different styles for the text can be defined before it is added. Once in the report, the text can be dragged to a different position. The 'Remove All' button of the text editor window deletes all custom text. Single text elements can get removed by selecting and pressing the 'Delete' key on your keyboard.
Add Shape: This option opens a shape editor window that allows you to add custom shapes to the report. Different styles for the shape can be defined before it is added. Once in the report, the shape can be dragged to a different position. The 'Remove All' button of the shape editor window deletes all custom shapes. Single shapes can get removed by selecting and pressing the 'Delete' key on your keyboard.
Screen Captures
As well as printing or exporting via the Context Menu, you can capture an InstantAtlas report as a screen capture. Make sure the graphics are as large as possible and then hold down Ctrl-Alt-Prnt Scrn on your keyboard. Open another application, such as Word or Power Point, and paste (hold down Ctrl-V on your keyboard) the screen grab. You can then edit the graphics (crop, resize, sharpen, etc) as required.
