There is no built-in method to automatically classify based on two different symbols with a symbology matrix in the end. Data Defined Symbology QGIS knows the concept of data defined symbology. This allows styling different aspects of the symbology each with an expression based on a different attribute. You can write a CASE statement for the line symbology ...

So, you have a polygon feature class where you have multiple polygons. Each polygon has a value stored in the field named Extra. You want to show polygons with unique colors. You should use the Unique values symbology in ArcMap. You can then choose what color your polygons with a certain value will show.

The XY to Line tool: Creates a new feature class containing geodetic line features... ...A geodetic line is a curve on the surface of the earth. However, a geodetic line feature is not stored as a parametric (true) curve in the output, but as a densified polyline representing the path of the geodetic line. If the length of a geodetic line is ...

In our office (we are a state agency) Federal Highways are Blue with slight black outline on each side of the line, State Highways are Red. Farm/Ranch to Market roads (small state highways) are Black or dark gray. County roads are slightly lighter gray. If a map is zoomed in close enough for city level roads they are kept a shade of gray as well. I cant ...

As commented by @MichaelMiles-Stimson: There is a limit to what can be done with a text formatting tag, the link you have refers to the text properties - not to a tag. To adjust this you will need to manipulate ArcObjects : IFormattedTextSymbol

Graduated symbology can only be applied to numerical fields. If turnover is stored as text field then it won't be possible to use it for graduated symbology. For ways to change the attribute type see: How do I change the data type in attribute table in QGIS

As I stated in my comment, this is probably a topological error. You may use the Repair Geometry tool to repair the polygon feature. Polygon fills bleed over or fill entire page when printing or exporting

After your edit, here's a suggestion. Stop using QML and switch to SLD. When you save the SLD from QGIS, it doesn't contain the labeling (at least not in v 2.7.2). SLD is an open standard by OGC based on XML schema. See the SLD spec here. Just create your style as before but export to SLD and you can edit in Notepad (using the SLD reference). I advocate ...

A line with arrows can be made with the line symbology, depending on the software you want to use: How to indicate flow of a watershed feature? . A simple > text symbology can work too. For the curved lines, you have to create great circle lines on a custom aeqd projection. See great circles in QGIS and export in 3857 webmap for a workflow.

Thanks Alex for the answer; I also found that the reason my view was not updating was simply to me loading it with the cache table option checked. Un-checking this fixed it.

IF you have a view in PostGIS, you could use that as the table that you edit, so long as you only edit attributes from the master table. You could concatenate the action fields (from the one-to-many relationships) so that you have unique combination of actions to symbolize on. My point is, visualising from a view out of postgis will ensure that it's always ...

I had a similar error with pseudocolor properties on macboook air mid 2011 OS x 10.10.4 This solved my problem: updated matplotlib using terminal reinstalled QGIS 2.8 Wien instead of QGIS 2.10 (http://www.kyngchaos.com/software/qgis)

This can be accomplished by manually defining the values for the classes. After choosing the "singleband pseudocolor" renderer, now you can press the 'plus sign' just above the value window and add custom classes and change the colors. You can also just hit the classify button and then double click the populated values and change them to the desired value. ...

Thank you so much for everyone trying to solve my problem. I finally figured out what was causing my error. It was not a syntax problem. The layer files which I was trying to use had source information in a table in a geodatabase. For some reason arcpy couldn't access it properly. I exported the source table to a shape file. Then remade the layer files so ...

A couple of different ways. If you find out that the breaking point for 25% is lets say 10000.02343 acres, go to Layer Properties > Definition Query and enter the limiting information. Shape_Area < 100000.02343. Then set symbology. Or Similar to what you were trying already, go to Layer Properties > Symbology > Quantities > Graduated Colors. Pick ...

I guess it is not (yet?) possible. See ArcGIS 10.2 documentation: For access to the complete set of layer symbology properties and settings, for example, changing individual symbols for individual classes, it is necessary to author these changes in the ArcMap user interface and then save those changes to a layer file. These custom settings can then be ...

i hope this is what you are searching for : Make sure you have right path to your svg directory go to layer properties>style, on symbol layer tab change it to svg marker (on pic)
