I want to display two charts (option bar/column) having the same scale using ArcMap 9.3. But there is no option to set the scale value for the bars in the table of contents. ArcMap automatically takes the mean value of the data set as scale (see marked layers in attachment). I want both layers (Hebungen and Fehler Hebung) to be scaled with 1 and to appear in the map with this scale. Does anyone know how to achieve that?
