4.3.4 Display of charts
You can display charts on the map representing figures of the database.
You start in the same way as explained above, i.e. including the database with numeric values for the percentage distribution of each pie chart. (If the database is not loaded, you have to load it: 'Choose database', see steps 1-3 of Chapter 4.2).
In Map Maker: Check that the values for the display in the loaded database are numbers by Project manager > Data link > Database: The left column must show 'integer'. If not, change the table (for example, in MS Excel). Also, check that the ID in the DRA file and in the source table match each other.
From the Project manager window: Style (1, see below) > Labels (2) > Option (3) > Data chart (4) > Select the data field (or fields) you want to display (5, here: MAL01, MAL02, MAL03, MAL04) > Data chart (6) >
> Select chart type (here: Histogram) > If required: Adjust 100% range and size of chart > OK
The histogram chart should look like this:
A pie diagram chart can look like this:
To create a small additional legend, as shown on the histogram chart above:
After you have selected the type of diagram (in example above: Histogram) and possibly edited the chart colours: Make legend > Make legend window: Size and title > Change size, font, colour if required > Labels > Enter short, but descriptive labels > Preview > Save to EMF file > Enter file name for EMF file > Save, and proceed as described above.
You call this EMF file through ‘map furniture’: Right-mouse > Map Furniture > Locate box on map, where the legend should be placed > Map furniture window: Furniture type: Enhance Metafile > Select EMF file, just created > Open > OK
(See also Chapter 6.3.1 for more descriptions on ‘map furniture’).
