The paper mentions the errors occuring most frequently in constructing chorograms and diagram maps. Examples of Czechoslovak maps are used to illustrate erroneous procedures which depreciate the expected results. With the chorogram it is the choice of relative values, with the diagram map the choice of absolute values.
