size of node with shape=circle - size

i'm trying to set the size of the nodes this way:
controller[shape=circle,width=.5,label="Controller",style=filled,fillcolor="#8EC13A"];
But all three nodes are with different size. How can i set fixed size?

From the DOT Guide http://www.graphviz.org/pdf/dotguide.pdf on page 4 it says the following:
When drawn, a
node’s actual size is the greater of the requested size and the area needed for its text
label, unless fixedsize=true, in which case the width and height values
are enforced.
Thus you simply need to add fixedsize=true to your code

ngx-charts-bar-vertical-2d minimum bar width

I would like to set the width of the bars to be a minimum of 12px. I would actually prefer to have a fixed width on the bars period.
As an example, when I am displaying 10 days of data, the graph looks fine, but for 30 days, it does not look good at all. Any thoughts on making this look better?
I added a horizontal scroll, but the width of the bars is automatically calculated based on the number of items in the graph, irrespective of the graph width. Is there any way to alter this behavior?
Screen capture: https://share.getcloudapp.com/yAubDN8X
Try adding [barPadding]="1" to ngx-charts-bar-vertical-2d element
<ngx-charts-bar-vertical-2d [barPadding]="1" ...>...</ngx-charts-bar-vertical-2d>
Try adding [groupPadding]="1" to ngx-charts-bar-vertical-2d element
<ngx-charts-bar-vertical-2d [groupPadding]="1" ...>...</ngx-charts-bar-vertical-2d>
as long as you minimize the padding between groups, the barWidth with grow automatically !

xcode - autolayout - prevent overlap of logo + input with footer button

I am having trouble preventing the text inputs from overlapping the footer button.
The footer has been anchored to the bottom of the screen. All the elements up top (logo, title label, and 2 input boxes) all have relative constraints. I try to add a constraint between that last input and the footer button but it pushes the footer off the screen on the smaller iphone.
What do I do??
https://github.com/civilordergone/taskfort_ios
Your issue seems to be in landscape only (I ran your code), where you have, for example, 320 points of vertical space, and an image (128pt), a text label (120pt), two text fields (30 each, for 60pt in total) and a 30pt button at the bottom. Already that's 338pt used, and we haven't accounted for the vertical spacing between your objects.
There simply isn't enough vertical space for all of these items to be vertically positioned while retaining their heights, so something has to be flexible: something has to be able to be vertically shrunk/compressed. Your logo and app name (Taskfort) are two candidates.
Here are some of the changes and/or points of consideration:
An ImageView with a height and a width equality constraint will always be that size, but for your layout, it has to be able to be compressed. I removed the height & width constraints and added an Aspect Ratio constraint, so the logo keeps its aspect ratio, but can now scale. I added a relationship constraint between the logo's left side and the left side of the Taskfort label.
The image has a relationship to the top of the screen, saying it must be equal or greater (not less than) to 0. This just means "the image can't be pushed off the top", which "less than" would allow it to be. (For example, if the image is pushed off the top by -40 points, that's still "less than 20").
The image has to be allowed to be vertically compressed. There is a property for "Vertical Compression Resistance" that was 250, and is now 249. By setting it to 249, we're saying "If something has to give way, vertically, this object can be compressed." Since we defined an aspect ratio constraint, if it does get compressed vertically, it'll be reduced horizontally by a proportionate amount so as to maintain the proportions of the logo.
To prevent the text fields from overlapping, their relationships are set to "equal or greater than". Same for the Username text field to the label.
The challenge was in defining the relationship between Password and the Create Password button at the bottom. I added a constraint that says their vertical distance must be greater than or equal to 20. This has a priority of 1000 (by default), so at all times, you get 20pt or greater between those two. Without this, your password field and your button overlap.
While step 5's constraint solves the overlap problem, it creates a new one in portrait orientation, where the password is now 20pt from the button, instead of being lovely white space. To fix that, we add a second constraint between the password field and the button, and specify that the vertical distance is to be 228pt between them both. Now that creates a constraint conflict because you now have two constraints that are both trying to define the vertical relationship between the button and the text field. The 20-pt one is required, it has to be there. But the other one is just a "nice to have, if we can fit it".
So you set the priority of the new one (the 228pt) to be low, such as a Priority of 250. Then the layout engine will use the required one (must be 20 pt or greater) and then it sees the other one ("make them 228") and it tries to do that. If it can't, such as in landscape, then it doesn't do it and doesn't complain, because you have the other constraint already that provides positioning information. If you're in portrait and you have enough space such that it can also apply the low priority constraint, then it'll do that too, and your portrait layout now gets a bigger gap between top and bottom.
When testing these layouts, use the Assist Editor in Preview split-screen mode so you can see the affects of your changes without needing to run the simulator. Here's a guide on that.
Sounds like you're using an equality constraint, such as "the distance between lastInput.bottom and footer.top equals 20". Instead, try an inequality operator, such as "the distance between lastInput.bottom and footer.top is equal or less than 20".
The attributes inspector for a constraint can let you change an equality to an inequality. Alternatively, you can double-click the constraint line (the UI in the storyboard editor) to get a quick pop-up for that.

Cannot change polygon 'size' every repeat in Builder

I'm using Builder v1.80.06
I can vary the position of a polygon every repeat easily enough
e.g. I have a Positions list
positions=[[1,1],[1.1,0.9],...]
and in the 'Position field' have :
$positions[0]
and then change it's value in a code block on each repeat.
BUT I want to vary the size in a similar manner with a $sizes list but get an error.
Looking at the generated code, the problem is at the object creation stage. the code generated is:
for a hard coded polygon (ie ok)
polygon_1 = visual.Rect(win=win, name='polygon_1',
width=[1.5, .2][0], height=[1.5, .2][1],
ori=0, pos=[0, -0.6],
lineWidth=1, lineColor=[1,1,1], lineColorSpace=u'rgb',
fillColor=[0,1,0], fillColorSpace=u'rgb',
opacity=1,interpolate=True)
for one populated by a variable (not working):
polygon_2= visual.Rect(win=win, name='polygon_2',
width=1.0[0], height=1.0[1],
ori=0, pos=[0,0],
lineWidth=1, lineColor=[1,1,1], lineColorSpace=u'rgb',
fillColor=[1,0,0], fillColorSpace=u'rgb',
opacity=1,interpolate=True)
It complains (rightly) that 1.0[0] makes no sense on the width and height parameters
Even though I have my sizes list instantiated in a code block right at the beginning of the experiment instead of reading $sizes[0] a default float value of 1.0 is used.
Any other suggestions for how to vary the polygon size dynamically at runtime using builder?
I could just take the generated code and drop it into coder I suppose and fix the problem but I want to hand this over to a researcher so would like for them to be able to maintain it.
thanks,
If you set size to be a tuple/list with a pair values [1.2,1.5] or [1,1] does that not fix it?
When you change attributes at runtime, just change the attribute of an existing stimulus instead of instantiating a full new stimulus. The latter is quite heavy on ressources, causing unreliable timing. So do
stim = visual.Rect(win) # instantiation, ressource heavy
stim.attribute = newValue # change attribute. lighter.
I can think of two ways you could do it in a pretty neat way. The first is to set width and height explicitly instead of the size attribute, but using a size-like value. So (removing all parameters not of interest):
polygon_2 = visual.Rect(win)
# Unpack the x,y-sizes to the stimulus .width and .height attributes
newSize = (1.5, 0.2)
polygon_2.width, polygon_2.height = newSize
The second, if the size attribute is really important to use, is to use the Polygin with edges=4 to make it a rectangle:
polygon_2 = visual.Polygon(win=win, edges=4, size=(1.5, 0.2))
# Setting size
polygon_2.size = (0.8, 0.4)
Do try Jon's suggestion first. But the idea with visual.Rect and visual.Circleis to use substitute Polygon's size and vertices for something more relevant. So size can do unexpected things if width/height etc. are not 1.

Two NSTextFields with interdependent widths in autolayout

I’m trying to put together what seems to be a simple case of two NSTextFields with dynamic width and fixed spacing in between. I cannot figure out an effective way to do so though.
I’m looking to get something like this:
The blue boxes are the NSTextFields. When more text is entered into one, it should grow and thus make the other one shrink, maintaining the lead space, trailing space and the spacing in between the fields. The first one should take the priority if both of the fields have too much text. Each field will also clearly have a maximum and a minimum possible width it can reach.
How would I go around handling this, preferably utilising IB autolayout as much as possible?
It seems to me that all of constraints you mentioned directly translate into interface builder --
First view has width >= something.
First view has width <= something
Same for Second view.
Space between views is fixed.
Second view wants to be as small as possible (have its width at 0) but this has lower lower priority than the previous constraints and lower priority than inner content size constraints.
The code I had to add to my view controller, after applying the constraints as per the ilya’s answer:
In controlTextDidChange (_controlWidthConstraint refers to the fixed width constraint of the input; it’s probably 0 by default for the second input):
// Get the new width that fits
float oldWidth = textControl.frame.size.width;
[input sizeToFit];
float controlWidth = textControl.frame.size.width;
// Don’t let the sizeToFit method modify the frame though
NSRect controlRect = textControl.frame;
controlRect.size.width = oldWidth;
textControl.frame = controlRect;
_controlWidthConstraint.constant = controlWidth;
The key lies in invalidating the intrinsicContentSize for the text field when text is input.

character is of string is always changing the position when ever I change the string value by using CCLabelBMFont

I update the score label when I'm playing my game and I display it by using CCLabelBMFont, when the score changes, each character of the score label always change the position of the label.
I want to keep it the same position!
Example: 00:01 take small space than 00:50; when the text change the CCLabelBMFont reposition the text again. help me , how to keep the same position?
Your bitmap font was created from a true type font that has a variable width.
Only fixed-width fonts like Courier will give you the same string width for the same amount of characters in the string. Strings drawn with non-fixed-width fonts will have varying width depending on the characters in the font, ie a 'w' character has greater width than an 'i' character.
Open FontBook.app (it comes with every Mac) and in the Collection panel select "Fixed Width" to see only the fonts with a fixed width. On my system I have these fixed width fonts installed:
FYI, Monaco is the default font used by Xcode.
It is hard to tell by the question, but my guess is that you are talking about the actual positioning of your label changing, meaning your alignment is not what you want it to be (justified left instead of justified right for instance).
Left Justified:
test
testtest
Right Justified:
test
testtest
If this is what you are talking about, you can change the text alignment by changing the nodes anchor point.
// for right justified
label.anchorPoint = ccp(1, 0);
When you are saying "always changing the position", do you mean "left side isn't staying in the same place"?
CCNode class has anchorPoint property, which determines which point of this node is "pinned" to the point in node's parent. Anchor point of (0, 0) means bottom left corner, (1, 1) - top right, (0.5, 0.5) - center. All positioning and transformations take place around anchor point.
Set anchorPoint property of your label to mean the point which you want to have "pinned" when content size of label changes. Examples:
if you want top left corner to be stationary:
label.anchorPoint = ccp(0, 1);
if you want the middle of left side to be stationary:
label.anchorPoint = ccp(0, 0.5);
