Gaia DR2
Plot type:Histogram bins the data by a single field and displays count of objects per bin.Heatmap bins the data by two fields and displays count as color.Conditional distribution bins the data by one field and displays the distribution of a second field within that bin as a boxplot (range and quartiles).Shows a scatterplot of a (random subset) of actual data points.
For log functionality, set the filter to enable only positive values.
For log functionality, set the filter to enable only positive values.
Count:Choose whether the object count per bin is shown in linear or log scale. Count is shown on the Y axis.Count is shown on the color (Z) axis.
