Elementul Scării Grafice

Scale bars provide a visual indication of the size of features, and distance between features, on the map item. A scale bar item requires a map item. Use the scaleBar Add Scale Bar tool following items creation instructions to add a new scale bar item that you can later manipulate the same way as exposed in Interacting with layout items.

By default, a new scale bar item shows the scale of the most recently added map item. You can customize it thanks to the Item Properties panel. Other than the items common properties, this feature has the following functionalities (see figure_layout_scalebar):

Scale Bar Units and Segments groups

In these two groups, you can set how the scale bar will be represented.

  • Select the units you want to use with Scalebar units. There are many possible choices: Map Units (the default one), Meters, Feet, Miles or Nautical Miles… which may force unit conversions.

  • The Label unit multiplier specifies how many scale bar units per labeled unit. Eg, if your scale bar units are set to „meters”, a multiplier of 1000 will result in the scale bar labels in „kilometers”.

  • The Label for units field defines the text used to describe the units of the scale bar, eg m or km. This should be matched to reflect the multiplier above.

  • You can define how many Segments will be drawn on the left and on the right side of the scale bar.

  • You can set how long each segment will be (Fixed width), or limit the scale bar size in mm with Fit segment width option. In the latter case, each time the map scale changes, the scale bar is resized (and its label updated) to fit the range set.

  • Height is used to define the height of the bar.
