Histogram¶
Here you will find the guide to every parameter of the histogram. If you need more generic information please see DataPlotly Basic Usage.
Plot Properties¶
Layer
: the combobox will display all the vector layers loaded in QGIS
X
: the values in this field will be binned and the count in each bin will
be represented as the length of the bars
Marker Color
: the color of the bars. To use different colors for individual
bars, enter an expression that returns an array of color definition strings
with as many elements as there are bars
For example
array('red','green','blue','yellow','purple')

array_foreach(
generate_series(0, 7),
ramp_color( 'Blues', @element/7)
)
