[GIS] Removing border of symbol in QGIS

qgis

I have a point layer in QGIS. I have created a
graduated color scheme, but it doesn't look good because
the border of all the symbols is showing and are overlapping (so you hardly see the color of the marker itself anymore).

Is there a way to remove the border of a standard symbol (symbol layer type: simple marker)?

The only thing I found with google was http://lists.osgeo.org/pipermail/qgis-user/2012-March/015778.html, but that was not very helpfull for me (I don't find the Outline option to set to None)

I am using QGIS 1.7.4

UPDATE: summary possible answers (thanks to @Marty and @SS_Rebelious):

Change the "Symbol layer type" from "Simple marker" to "Font marker" (in symbol selector window), select the '.' symbol and change the color.
You can set the border color to the same RGB value as the fill color (but this is a lot of manual work if you have a graduated color scheme => you have to do it manually for each class).
Another option is to use Old Symbology where you have the option to set the 'outline' to 'None'. However, the graduated color scheme is not as advanced as in the New Symbology (no color ramp to choose) and you have to set the outline for each class manually.

I used the first option, as this is the most automated way.

You could try: Layer properties -> Style -> Change -> And set the border color to something else.

[GIS] Proportional Symbol Formatting

There is a very simple solution to this. In QGIS, double click on the layer you are dealing with. Then go to the Style menu. In the Style menu, set your classification to “Graduated”.

Then, double click on your symbol. This will take you to a menu where you have the option of changing your symbol layer type from “Simple fill” to “Centroid fill”.

Once you have done that, see the symbol layers bar in on the left and click Marker. Click “circle” for your symbol type. Then change the size and color of your circle accordingly. Simply repeat for your other symbols.

[GIS] How to define border colour for rule-based style using PyQGIS

Since you want the border color to match the corresponding polygon fill, you can use the data defined property @symbol_color, which returns the fill color for each polygon. Then, for the default polygon symbol (which is the base of your QgsRuleBasedRendererV2) you set its color_border property to @symbol_color:

ddp = QgsDataDefined( True, True, "@symbol_color" ) # active, useExpression, expression
symbol.symbolLayer( 0 ).setDataDefinedProperty( "color_border", ddp )

Your script would become this:

from PyQt4.QtGui import QColor

layer = iface.activeLayer()
style_rules = (
    ('First', 'expression_1', '#dbffdb'),
    ('Second', 'expression_2', '#f0ab64'),
)
symbol = QgsSymbolV2.defaultSymbol(layer.geometryType())
ddp = QgsDataDefined( True, True, "@symbol_color" )
symbol.symbolLayer( 0 ).setDataDefinedProperty( "color_border", ddp )
renderer = QgsRuleBasedRendererV2(symbol)
root_rule = renderer.rootRule()
for label, expression, color_name in style_rules:
    rule = root_rule.children()[0].clone()
    rule.setLabel(label)
    rule.setFilterExpression(expression)
    rule.symbol().setColor(QColor(color_name))
    root_rule.appendChild(rule)

root_rule.removeChildAt(0)
layer.setRendererV2(renderer)
layer.triggerRepaint()

On the other hand, to set the same border color for all polygons in a Rule based renderer, you would use setBorderColor() in this way (after initializing symbol variable):

symbol.symbolLayer( 0 ).setBorderColor( QColor(255,0,0) )

Just tested it on QGIS v2.14.8. Let me know if it works on your QGIS installation.
