21

22
+ To access the available customizations for any chart, click the
23
+ :guilabel:`Customization` tab above the :ref:`encoding channels
24
+ <encoding-channels>` in the :doc:`Chart Builder </build-charts>`.

30
+ Custom Color Palette
31
+ ~~~~~~~~~~~~~~~~~~~~
32
+
33
+ The color palette specifies the range of colors that corresponds to
34
+ relative aggregated values in your map.
35
+
36
+ :ref:`Geospatial Scatter <scatter-ref>` charts use a discrete color
37
+ picker, and :ref:`Geospatial Heatmap <geospatial-heatmap-type>` and
38
+ :ref:`Choropleth <choropleth-ref>` charts use a gradient color picker,
39
+ but the mechanism to enable customization is the same. To enable
40
+ palette customization, toggle the :guilabel:`Custom Color Palette`
41
+ switch in the :guilabel:`General Customization` section.
42
+
43
+ For more information, see :ref:`Color Palette Customization
44
+ <color-palette-customization>`.
45
+
46
+ Automatically Set Viewport
47
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
48
+
49
+ By default, geospatial charts show a map which includes all the data
50
+ point markers in your specified collection. You can pan and zoom to
51
+ change the map view, but if you close the chart and re-open it the map
52
+ reverts to its default state. This behavior is controlled by the
53
+ :guilabel:`Automatically Set Viewport` option.
54
+
55
+ When you toggle the :guilabel:`Automatically Set Viewport` switch to
56
+ ``Off``, the area and zoom level at which the map is saved becomes the
57
+ new default view.
58
+
59
+ .. note::
60
+
61
+ You can pan and zoom the map area in a chart on a dashboard, but
62
+ these changes do not affect the default map view.
63
+
64
+ Opacity
65
+ ~~~~~~~
66
+
67
+ The :guilabel:`Opacity` level of a map modifies the degree to which
68
+ the chart's map data shows through the data point markers. This
69
+ setting is available on all geospatial charts.
70
+
71
+ On :ref:`Geospatial Heatmap <geospatial-heatmap-type>` and
72
+ :ref:`Choropleth <choropleth-ref>` charts, the :guilabel:`Opacity`
73
+ level defaults to 100%. On :ref:`Geospatial Scatter <scatter-ref>`
74
+ charts, it defaults to 20%.
75
+
76
+ Radius
77
+ ~~~~~~
78
+
79
+ .. include:: /includes/radius-description.rst
80
+
81
+ Stroke Thickness
82
+ ~~~~~~~~~~~~~~~~
83
+
84
+ :ref:`Scatter <scatter-ref>` charts provide the customization option
85
+ to set the :guilabel:`Stroke Thickness`, measured in pixels, of the
86
+ map's data point markers. This setting defaults to ``2``.
