Turns out the "Detect field types" in import layout had become 
unchecked.

Thanks for suggestions.

If the data is being read as a character versus a integer or decimal, 
you cannot use graduated symbols. Double left click on the layer in the 
legend and select properties. Select the Fields tab and see what format 
the attributes are being read as.  I have run into this when generating 
a csv from a spreadsheet from  different language.  I would convert the 
format in excel or livre office and regenerate the csv file. 
Alternatively you can use  text editor to replace the quotes on each 
value in the existing csv.

Hi Kirk,
Yes coming up as text whereas another file of diff data which comes up 
fine is "double".
Csv file generated from xlsx file which is my SOP, not happened 
previously & been using QGIS for 10yrs+.

Can redo as has been thru a few mods.

Re: [Qgis-user] Symbology

[chris hermansen via Qgis-user]

If your layer is a CSV file, do you not first need to convert it to a
spatial form, for example a shapefile?

In case I misunderstand, if it came from a CSV file, then as Barend
suggests, maybe the type of the column is incorrect.  You can use a CSVT
file to define column types prior to conversion; alternatively you can add
a new column of type integer for example, and convert the string value to
integer.

Re: [Qgis-user] symbology shapefile polygons: equal intervals classes

[Charles Dixon-Paver]

I'm not sure of a faster way to achieve this exactly, but if you use the
"pretty breaks" method and the appropriate number of classes you can get
quite close to the desired outcome, and maybe just remove the last class
created to round down the output. Pretty breaks will try to automatically
perform some serious rounding to get more human-friendly values than
natural breaks. Precision and trim options can help clean up the legend
results as well.

Try something like

You may want to read the help of each involved function to better

Hi All,

Any help would be much appreciated,  sorry for just throwing this out 
there... QGIS is very new to me.


I have lots of tables that I would like to apply common symbology and 
best I explain with an example:


table_a.foo_blah
table_b.boo_blah
table_c.whatever_blah
table_d.i_cant_believe_its_not_butter_blah

Q: What would the expression be to find the field ending with "_blah" 
and use/return that fields value (as the symbology's categorical 
value)? I will never know what the field is called, just that it 
always ends in _blah.


Big thanks in advance,

Re: [Qgis-user] Symbology blank

[Thayer Young]

 Hi Ruby,
Building on the answers of the others:
1)  You may not have any geometry in your layers, so there is nothing to 
display in the symbology because there is no geometry type.     a) For example 
if you only have an attribute table, for example the '.dbf' of a shape file, or 
a text file like a '.csv' file, or the text file has been imported without 
geometry, in which case you need to open it again.     b) You may have done the 
join in reverse. You may have joined the geometry layer to the attribute/text 
layer. That would result in there being no geometry.          i) Open the other 
properties dialog of the other layer and see if there is something in the 
symbology tab.             a) If so remove the join from the first layer, and 
do the join from the other layer instead.             b) adjust the symbology 
in whichever order you see fee it will not make a difference.            c) if 
not you may not have any geometry, so there is no spatial information to 
display symbology for.
2) If you look at the top of Properties dialog do you see a drop down menu that 
says "No Symbols" and a line of text in the middle of the dialog that says "No 
symbols will be rendered for features in this layer." In that case you just 
need to switch the dropdown menu to your desired display type that is 
appropriate for the data type of the fields (see Richard's answer).
3) Kirk's answer is not applicable :-), since a layer with geometry but no 
features should still have adjustable symbology. 
-Thayer

Is the type of your column you want to use ok (depending on the type of 
symbology you want to use)
?
If you want to use a graduated symbol, you need to have numbers. If you data 
has string as type, you can easily use an expression (the little button next to 
the drop down) to 'cast' your string to int or double. Another option is to fix 
this in the join or your original data.

Re: [Qgis-user] Symbology export for Geopackage?

[Andreas Neumann]

Hi Morten,

This is about saving OGR feature styles (e.g. for DXF and KML export). 
It has nothing to do with QGIS styles.


I agree though, that it is a bit confusing and one of those things that 
should be improved or removed in QGIS 3.

Re: [Qgis-user] Symbology export for Geopackage?

[Andreas Neumann]

Hi Morten,

The current way of saving styles in geopackage is through the Layer 
properties dialogue --> "Style" tab.


If your data source is Geopackage it will offer to save the style in the 
same geopackage. It is the same way as you would save a style in Postgis 
or in SpatiaLite.


If you think there is a better way than the above (e.g. when saving a 
layer also save the style), please open a feature request with a 
detailed proposal, or even better try to find a developer who would 
implement it for you.


Greetings,

Andreas

The Geopackage seems like a nice format for exchanging data, symbology etc.
in one file and I can manually from layer properties store the layer style
in the Geopackage.

But already when I choose "save as" in the layers panel to add my data to
the geopackage I am presented with the possibility to export the symbology
together with the data which would save me a lot of clicks (I have several
projects with 20+ layers)

But it has no function choosing that.

Should it work or am I doing something wrong?

And I do not understand the two alternative choises:
* Feature Symbology
* Symbol layer symbology

Any experience on this subject?

Hi Joris,
Thanks, that's useful and kind of does what I want though it does seem to

Don't suppose you (or anyone) knows where the tracker for it is? Its plugin
page points to itself being the tracker. :-S

 Hi List,

 General curiosity question.

 When using Save Vector Layer as to save a vector layer, there's an
 optioon:
 Symbology Export



 This in turn has three options:

 No Symbology

 Feature symbology

 Symbol layer symbology



 What does this do? I've tried exporting to both KML and TAB files using
 these options but they don't appear to keep the symbology.



 Cheers,

 Jonathan

 Hi Andreas,Thanks for further testing. I figured if something as simple as
a fill wasn't implemented then catogorisation probably wouldn't be.
 
 A further thought - not all vector formats support styling (shapefile
being the most notable exception). Should it remain a general option or be
moved to Datasource Options for any supported style?
 
 I lean towards the later option myself.


Well, shapefiles may not support styling or then they do. Read page 15 of
the document
http://latuviitta.org/documents/Geospatial_PDF_maps_from_OSM_with_GDAL.pdf
There I show how it is possible to use OGR_STYLES with shapefiles and
convert the result into a geospatial PDF map.

I would rather say that only a few software support styling vector data with
OGR_STYLES.

Re: [Qgis-user] Symbology Export

[Andreas Neumann]

Hi Jonathan,

This was originally introduced for DXF export to keep symbology as good
as it can - which is now in its separate function (Project - DXF
Export) and not in the save layer as anymore.

It uses the OGR feature styling, which in itself is rather limiting.
This isn't widely implemented and tested. Would be nice if some devs or
interested customers/users could give it some love.

Re: [Qgis-user] Symbology Export

Hi,

Actually it is not tied to DXF, but DXF was the reason why it was
introduced. It is just generic OGR feature styling.

Maybe it should be removed/hidden/disabled because DXF now has its
separate export. Maybe assign Marco Hugentobler to this ticket as he
worked on this.

Unless someone wants to work on it and improve it.

Does it not work at all with KML? Not even a simple line color?

Hi Jonathan,

The thread you are quoting is from 2011. The OGR feature styling was
introduced later (in late 2012 or early 2013 I think).

So did you really test KML export with Feature symbology or symbol
layer symbology?

I just tested it with QGIS master and with line features and different
line colors. It worked. What did you do that it did not work? What
steps? Do you have project/data to share?

Re: [Qgis-user] Symbology Export

[Jonathan Moules]

Hi Andreas,
I'm testing with a simple polygon that's using the default style QGIS gave
it (so basically black border and a random fill colour).
I've exported using both options - all I get in the KML file is a black
border, no fill.
I can change the colour of the border in QGIS and it changes in the KML
file. So I guess that's a very partial implementation.

*However* - If I set it to no symbology I still get the coloured
boundary. So changing the value appears to do absolutely nothing which is I
guess what I saw when I first tested it (a while back). Hence my wondering
what it actually did.

Can you confirm this behaviour? It seems superfluous to have an option that
is ignored.

Jonathan

Re: [Qgis-user] Symbology Export

[Andreas Neumann]

Hi Jonathan,

I can only partially confirm what you describe.

I agree that for area feature the feature styling does not work for KML.
However, for line features, it works fine and there is a difference
between the three options. The no symbology only exports a single line
color, the feature symbology correctly exports the colors assigned to
the categories and the symbol layer symbology exports line features
multiple times in case of multiple levels in the line symbology.

So I'd rather improve this than remove it. If someone could work on the
area feature styling it would be great. Or maybe hook up with the OGR
project if things don't work as expected.

 Hi,

 Actually it is not tied to DXF, but DXF was the reason why it was

 Maybe it should be removed/hidden/disabled because DXF now has its

 Unless someone wants to work on it and improve it.

 Does it not work at all with KML? Not even a simple line color?

 Hi List,
 General curiosity question.
 When using Save Vector Layer as to save a vector layer, there's an
 optioon:
 Symbology Export

 This in turn has three options:
 No Symbology
 Feature symbology
 Symbol layer symbology

 What does this do? I've tried exporting to both KML and TAB files
 using
 these options but they don't appear to keep the symbology.

Re: [Qgis-user] Symbology Export

[Jonathan Moules]

Hi Andreas,
Thanks for further testing. I figured if something as simple as a fill
wasn't implemented then catogorisation probably wouldn't be.

A further thought - not all vector formats support styling (shapefile being
the most notable exception). Should it remain a general option or be moved
to Datasource Options for any supported style?
I lean towards the later option myself.

 Hi Jonathan,

 I agree that for area feature the feature styling does not work for KML.
 However, for line features, it works fine and there is a difference
 between the three options. The no symbology only exports a single line
 color, the feature symbology correctly exports the colors assigned to
 the categories and the symbol layer symbology exports line features
 multiple times in case of multiple levels in the line symbology.

 So I'd rather improve this than remove it. If someone could work on the
 area feature styling it would be great. Or maybe hook up with the OGR

Re: [Qgis-user] Symbology Export

Hi Jonathan,

I think this option should be disabled if a format does not support
feature styling. I don't know if OGR provides this information?

http://www.gdal.org/ogr/drv_kml.html
says about KML:
Limited support is available for fills, line color and other styling
attributes. Please try a few sample files to get a better sense of
actual behavior.

Hi Nathan,

Thanks for your reply. We'll switch to manually editing the qml-file for now.

However, I would say the feature could have been thought through a bit more. 
The button 'classify' now seems superfluous, and there is no way to prevent an 
update when changing layers. Perhaps the button 'classify' could be replaced by 
an option to automatically reclassify. Another option would be to add a 
classification scheme 'manual' which copies to the current classification when 
selected, but retains its values when changing columns.

I think there are many users (I know 3 of them in my company) that create 
multiple maps with the same classification, so an update would be very welcome 
:)

 The column list is not populated for graduated symbology, but works
 for categories. The issue repros with QGIS v.1.7.4 and v.1.9, but not
 with other shapefiles. This leads me to believe it is a formatting
 issue with the shp file or column names. 
 
 
 I'm not sure what's wrong with the table format and can't seem to find
 any other bugs like this online. I'd appreciate some assistance in
 unblocking this issue. Shape file can be found here, on Dropbox.

Hi Marco,

I don't know if I'm wrong but it seems to be that Arthur was referring
to another thing.

When creating symbology classes in the old symbology you are allowed to
select more than one class at the same time and change the settings for
those classes.

In the new symbology you can't, is one of that missing features that the
old had and the new one doesn't.

There is a ticket already filed about this issue.

It seems that is it is not a QGIS problem, 

Now off to the mapserver list, as I can't see any way of setting this in 
Mapserver!

As you suggested, the getfeaturetype request shows all fields except geometry 
as strings:

 Hi,

 It seems, with the WFS plugin, that QGIS sets all attribute types to
 string, and therefore users cannot scale symbology on an attribute with
 a WFS layer.

I do not confirm this. In my case, WFS keeps numeric values.
All the best.

RE: [Qgis-user] symbology Unique Value from Postgis Table

[Michael Diener]

Hi Mike,

Yes there are some spaces it the fields and some '-' and '_'
Field data type is:  character(33)

I did try it out on other fields and it DID   work just fine that is why I'm
stuck.

Do I need to remove all special characters and spaces?

Cheers
michael

Hi Michael,

Do you have any odd names (spaces or case) in your
dbname/schema/table/column/datatype? What is the data type of the
field you are attempting this with? Have you tried making a unique
classification on other fields or tables with the same unexpected
result?

 Hi,



 I have tried everything possible to get my postgis Polygon table to
display
 a unique value as a thematic map.  It generates the legend nicely but
won’t
 display it in the map window all polys get the default color no matter
what
 I try.



 System:  qgis 1.4 build revision 12728  Windows XP  sp 3



 KML or shp work fine using the unique value symbology



 Is this a bug or am I missing something obvious, just not obvious to me
yet.

It's a bug, I can reproduce it with QGIS 1.4. The problem is the data
type character(33). Can you change your data type to character
varying(33)? In pgAdminIII this is really simply to do. After this
change, the styles should be applied to the map as well as the legend.

I'm just going to test it with the latest trunk build, and I'll file a
bug if I can reproduce the behaviour there as well.

 Hi,

 I discovered that field-based rotation for symbols in symbology-ng is not
 supported. Is it true?

That's true. Hopefully it will get implemented in some future version.

Hi,

Le Thursday 12 March 2009 16:03:16 G. Allegri, vous avez écrit :
 PS: it's strange. I remembers that on Linux I could multiple select
 the classes, while it doesn't work on the Windows version. Am I wrong?
 I don't have my Ubuntu to verify it...

You are right, if I understand correctly you can select multiple classes on 
Linux.

Y.
