Data analysis

EasyMap offers different types of data evaluation in analyses. Depending on the data type, the selection is different. The data evaluation determines how the characteristic values of the respective analysis are calculated.

Classified

Color, size, symbol, etc. are controlled by value classes. EasyMap offers different methods to create value classes automatically. However, these can also be adapted individually. More about creating value classes here.

Continuous

The continuous data evaluation offers you the comfort of receiving an analysis output that displays the values in a continuous color gradient without specifying value classes. This type of data evaluation is only offered for number columns.

  • Use the slider to the left of the gradient to change the gradient. This allows the color ranges to be increased or decreased over the entire data area.
  • Set a analysis range if the gradient is not to be calculated over the entire value interval (i.e. the range from minimum to maximum).
  • If you change the gradient via the Colors > Edit gradient button, reverse the gradient via Reverse gradient. You can also set a transparency for the colors .
  • Via the Colors and Interval button you can save colors and value intervals once they have been defined and copy and paste them again. Similarly, you can only save colors or load existing gradients.

Proportional

When classifying symbol sizes or line widths, data evaluation is offered proportional. This allows continuous sizes or widths to be calculated which are calculated directly from the analyzed data value using a factor.

Data-Driven Height/Width

The height or width of the visualization is calculated linearly proportional to the data value. This can lead to very large scattering of the diagram or symbol sizes. The cause can be easily explained, if you assume that a circle is used as symbol, the setting Data Value Determined Height/Width causes a circle to become a twice as large data value twice as "high". But a circle with double diameter has four times the area! This should be taken into consideration and that the eye unconsciously perceives the size of many shapes rather over the surface than over the height or width.

Value specifies area

With this option, the area of a chart or symbol is calculated in linear proportion to the data value. Even when the data spans a wide statistical range, this does not usually lead to chart or symbol sizes greatly varying. Please refer to Data-Driven Height/Width to learn why this is the case.

Dynamic resizing of Data Change for a diagram or Symbol analysis

If you change the controlling column(s) during a diagram or symbol analysis, the new data values may lie in a completely different value range than before. This can lead to the fact that the proportionality factor used so far is unsuitable for the size determination, because the diagrams or symbols are now all much too big or much too small. In such cases it is therefore useful to choose Dynamic size adjustment after data changes not to retain the proportionality factor (Ratio preserved) but to retain the maximum size.

  • Preserve ratio: This setting maintains the value entered in the 1.00 cm equivalent to field.
  • Preserve max. symbol size: This setting maintains the value entered in the Maximum field.

Preset

The default data evaluation is only available for the color property. The Default option is useful if the colors for the areas in a data table are available as RGB values (hexadecimal, e.g. #00FF00). The data column with the HTML color coding should be present in the selected table and selected here.
