It seems like there's no way to just symbolise the line as a zigzag: unfortunately, you'll have to alter the underlying data. You can get a reasonably good zigzag line by first splitting the original line into many equidistant line segments, and then offsetting every other point by a fixed amount. Here's a Python script that does this, taking NathanW's ...

In QGIS 2.4 there is a Standard Deviation mode in symbology like on the picture below: You have to choose the attribute column of the data to be presented, the number of classes you wish to have and the colour ramp with two different colours. You can also define custom intervals if you would like to, just be sure that you edit the labels too, so they will ...

In InkScape, try saving the image as "Plain SVG" if you're not already doing so. Also try positioning the center of the flag in the upper left corner of the canvas (this is origo of an SVG.)

Nope, you're pretty much bang on! You have to create a folder called "svg" in your ".qgis2" directory. You should be able to find this in: C:\Users\(your user name)\.qgis2 Then create the new svg folder, insert your flags in there and you should be able to see them in your Style > Symbol interface: For me, QGIS did tend to run a bit slow so it may be a ...

You may find some symbols here: http://geo.distortions.net/2010/12/geologic-symbology-for-qgis.html http://hub.qgis.org/issues/1694 https://hub.qgis.org/wiki/17/Geologic_Cross_Section and a Howto: http://gmcgeology.blogspot.de/2014/05/creating-geologic-maps-in-qgis-strike.html I assume that the people behind those pages have the geological background ...

I've tried to do this before and haven't had much luck. qGIS places repeated symbols on a line based on one reference point (by default, the center, though you can set it to top/middle/bottom x left/center/right), and rotates that symbol based on the slope of the line at that point. On a straight line, where the slope doesn't change from one symbol ...

You could try this in two different ways, either rotating your symbology (mark each location with a symbol that points at ), or rotating a label (each location has a static point symbol, and label rotated). Here's the Esri help page for each method: Rotate the label: Setting label rotation using a numeric field. I think this would work better for your ...

You should install R and enable R support in Processing Toolbox settings. In R branch of scripts find Basic Statistics -> Summary statistics and execute it for the attribute you are working with. You will get the mean value and the standard deviation in the output among the other data. Then using field calculator create a new attribute and fill it with ...

You can only symbolize by a maximum of 3 fields, and to do that you need to select: Unique values, many fields Under Categories, on the left side of the window. But, if you want to symbolize based on the 15+ fields in your screenshot, you might want to rethink your approach. You could always create a new field, and field calc the values of all the other ...

The vertices function might help you, as documented in the GeoServer manual. I used this to show cadastral survey points.

Do not rotate the Data Frame. Try instead to change the 'Central Meridian' of your selected projection (right-click in the Data Frame and select properties. Switch to Projection tab and double-click the selected projection).
