Is it possible to use mapinfo embedded graphic style for features with mapserver?
I don't want to describe again width and color of lines, polygones and so on.
The styling should be picked up automatically:
http://mapserver.org/input/vector/mapinfo.html
MapInfo files already contain styling
information. This styling information
can be used optionally by specifying
the STYLEITEM “AUTO” parameter in the
LAYER object of the map file.
Note
If you use STYLEITEM “AUTO” you must
have an empty class in the layer.
Example:
LAYER
NAME Elevation_Poly_5
TYPE POLYGON
STATUS DEFAULT
CONNECTIONTYPE OGR
CONNECTION "./hypso/elev5_poly.TAB"
STYLEITEM "AUTO"
CLASS
NAME "Elevation Poly 5"
END
END # Layer

I have n polygons with ids "test-1-1", "test-1-2" .... "test-1-n" which represent a single logical entity. Format of id can be generalized as < entity_name>-< entity_id>-< i>, where i is added to distinguish ids of multiple polygons.
My query here is, I want to display only "test" when any of these polygons is clicked. Currently id of selected polygon is displayed in info-box.
Is there any cesium way to do this? I would not prefer manipulating the strings at runtime.
A Cesium Entity has three fields of interest to the InfoBox (the thing that pops up when an Entity is selected).
entity.id - Each entity in a dataSource is required to have a unique id (a GUID will be auto-generated if no ID is supplied at creation). It is an arbitrary string and does not need to be human-friendly.
entity.name - This is the human-friendly name of the Entity. It does not need to be unique, you may have as many duplicate names as you like. It is half a line or less of plain text (not HTML).
entity.description - This is a sandboxed HTML description of the entity, and can span multiple paragraphs or include tables and other styling.
The InfoBox will attempt to show entity.name on its title bar by default, and will only fall back to show entity.id in the title bar if name is missing (because name is optional, id is not).
The body of the InfoBox only appears below the title bar if entity.description is set (otherwise only the bar is shown). The description is rendered with a sandboxed iframe (to offer some resistance to cross-site scripting for apps that display user-supplied entity descriptions).
I have n polygons with ids "test-1-1", "test-1-2" .... "test-1-n" ...
For this case, I would keep the existing ids, and set name to be the string you wish to see in the InfoBox popup. Multiple entities can have the same name but not the same id.
I am using D3plus for data visualization . but in the x axis wrong data is showing instead of what i wrote in .x("year") to show .
http://jsfiddle.net/MituVinci/a77kz0dr/
enter code here
var visualization = d3plus.viz()
.container("#viz") // container DIV to hold the visualization
.data(sample_data) // data to use with the visualization
.type("scatter") // visualization type
.id("Reason") // key for which our data is unique on
.x("year") // key for x-axis
.y("Female") // key for y-axis
.draw()
I also want to resize the width and height of this and also want to show it using an external json file how can i do it ?
Since you have "Reason" as your .id() variable, D3plus is aggregating all data points that have the same "Reason". So the "x" position for "Family Feud" is 2010+2011+2012+2013+2014 or 10060, which is where all of your bubbles are located.
If you want to display each bubble individually, you could create a separate variable called "ReasonYear", concat the text of the Reason and Year fields together and then use .id("ReasonYear") for your visualization.
Use .width() and .height() to control the width and height respectively of your visualization.
Use .data() to load data from an external JSON file

I am trying to apply the least squares to my data using the built-in Voigt model from lmfit.
But I have to call the Minimizer class to apply the least squares method, which requires a function.
And I don't have a function since I used the built-in model given by lmfit. There's no simple function I use for Voigt model.
What is your recommendation?
Minimizer class: (http://lmfit.github.io/lmfit-py/fitting.html#module-Minimizer)
I was initially trying to change xtol, ftol and gtol values of the least-square which are 10^-7 by default, and for that I thought I need to call the Minimizer class. However, I could change tol values simply by adding them to model.fit:
output = model.fit(input_y, parameters, x=input_x, \
fit_kws={"ftol":1e-22, "xtol":1e-10, "gtol":1e-22})
Here the output is the model(s) using lmfit.
I have a mobile app built in as3/air for mobile devices and I am wondering what the best approach to handle textinput fields are.
What I mean is I have multiple input fields on multiple screens. The inputs have a label (textfield), background color under the label (quad) and an input (textinput). Some are password, some are not. Some are different width/heights, multi-line/single line etc. All however use embedded fonts, have a name and ID assigned etc.
I have created a class file that extends Sprite and built all the components of the textinput (textfield, quad, textinput) so my other classes/screens can just create a new instance of this class passing custom values.
var textField:TextFieldClass = new TextFieldClass();
textField.DrawTextField(name, ID, width, height, isPassword, hasLabel, labelPosition etc);
The above works great. I can reuse the class to draw multiple textinput on screen with minimal code however I am having trouble getting the text value/ID/name when there are multiple instances.
I have tried adding each textField instance into an array and iterating through but that gets x number of the last textField instance e.g. if first instance is named txtEmail and the second is txtPassword, I get 2 txtPasswords.
I have also tried getChildByName and specifying the name of the textinput but when I use txtEmail I get a cannot access null value but txtPassword works.
Maybe I am going about this wrong so happy to use a better approach if one exists (which I am sure there is). Basically I would like to have a reusable textinput class that allows custom design (quads, fonts etc) without having to copy paste the entire textinput code for each new input field.
Thanks
I think the title should make it pretty clear. I was wondering how you can assign a class to an object on stage. As you would do with actionscript:
var objectname:ClassName = new ClassName();
This would make a new object, but the current object already exists, it just needs to be notified that it's of the type "ClassName" so it can inherit it's properties.
I've also tried assigning the "ClassName" in the linkage as either the base path or the class name. But in either situations I get an error saying that the class needs to be unique when I use the same class on multiple objects.
So I would need something like
//example exists on stage
example.class = ClassName
Thanks
I will answer your question with a question : why are you assigning the same class on multiple objects?
If what you want is a common behavior for those objects, you should create your class and assign it has the Base Class on those objects.
I don't think there's a way to do just do that. But I do suggest you look into the decorator design pattern The idea here is that you don't change the class, but you "decorate it" with more functions as needed.
Hope this helps !
You seem to have this the wrong way around. You define a class in order to set specific behavior & properties for an object. In a real life example, if I want to build a radio , I will come up with a radio design & implement it. Now if I need several radios, I will use the same implementation to manufacture them.
If I now wish to turn my radio into a TV , I can't just tell my radio, hey , you're a TV now. I can either decide beforehand that I want a radio/tv object and switch behavior whenever necessary or I can create a new TV object and add the radio functionality to it by adding a radio component to my TV object.
var radio:Radio // your current object
//example 1
radio.switchToTv();
//example 2
var radioTv:Tv = new Tv( radio );
