When creating a bubble chart, such as https://www.amcharts.com/demos/bubble-chart/, is it possible to ensure the chart area/grid is square without specifying the chart div width and height? I'm hoping it could be somewhat responsive. No matter what the window size, the chart 's grid is square. It would need to take into consideration any axis labels.
I'm using React/TypeScript. Thanks!
After struggling with amchart settings to no avail, the following solution works. However, seems like there should be away to do in with chart settings.
This article explains how to maintain a specific aspect ratio for images. I simply adopted it for the bubble chart.
<div style={{ position: 'relative', paddingTop: '93%' }}>
<div id={chartId} style={{ position: 'absolute', top: 0, left: 0, height: '100%', width: '100%' }}></div>
</div>
Create a container div with relative positioning and the top padding to the correct aspect ratio
Create the chart div as a child with absolute positioning
Render the page
Take a screenshot, paste it in your favorite image editor
Measure the pixels
Recalculate the top padding
For my chart, which has axis text on the left and bottom, 93% was perfect. Now, no matter the page width or device, the grid is always square. HTH.

It seems like the height and fixedBarHeight cant both be used in a rowChart. Ids like to use fixedBarHeight so all the bars have the size I want, and the chart to be in a scrollable div so that the numbers of bars define the height of the chart. Is this possible?
#ialarmedalien made this block, which introduces a dc.axisChart to separate the axis of the row chart from the actual chart.
Then you can use conventional overflow-y: auto on the row chart div.
Here is a related issue on dc.js.
The dc.axis addon mentioned by #Gordon will solve the problem with the axis in a scrollable div, but not the problem asked. By default, the axis will only appear at the bottom, not before.
To solve this, add one div after the row chart div, this div will contain a copy of the axis.
<div id='row-axis'></div>
Then initialize this axis in the javascript
dc.axisChart('#row-axis')
.margins({ left: 10, top: 0, right: 10, bottom: 10 })
.height( 50 )
.width( 300 )
.dimension( dimension )
.group( group )
.elasticX( true );
Then change the margin of the row chart to 'glue' correctly with the axis. They also must have the same width.
.width(300)
.margins({ left: 10, top: 0, right: 10, bottom: 0 })
Then , in the css
div.dc-chart {
float: none;
}
Dont forget to include overflow-y: auto for the row style. Then you get:
This however doesnt solve the gap problem if your height is too large (or too small) compared to the fixedBarHeight.
But now your margin is zero, so the proper height is easy to calculate (but you must pass the gap value, which has 5 by default). Assuming N=chart.group().all().length, then do:
.fixedBarHeight(X)
.height(X*N + gap*(N+1))
Which will give you:
Worth mentioning that at this point you dont even need the fixedBarHeight anymore. Simply setting the height using XN + gap(N+1) will result in dc auto setting this value to X.

Just add style="overflow-y: auto; height: 300px;" in your rowchart div. It should work.
I try to create a View with an Image and a Text component that wraps around the Image component.
My styling:
textContainer: {
flexDirection: 'row',
},
text: {
flex: 10,
},
image: {
flex:1,
height: 180,
width: 150,
margin: 10,
borderColor: '#ccc',
borderWidth: 1,
}
My component:
<ScrollView style={styles.contentContainer} >
{this.props.content.title_1 ? <Text style={styles.title}>{this.props.content.title_1}</Text> : null}
<View style={styles.textContainer}>
{this.props.content.text_1 ? <Text style={styles.text}>{this.props.content.text_1}</Text> : null}
{this.props.content.image_1 ? <Image width={null} height={null} style={styles.image} source={this.props.content.image_1} /> : null}
</View>
</ScrollView>
This is what the result: (not wrapping at all haha)
In the image beneath here, I quickly hacked the little image into the text. But I can't get the text to be wrapped around..
I hope anyone can help me in the right direction!
This is really hard but there is one weird way to do this.. Try the following. It worked for me but place I am doing this is too deep in the other views.:
<Text>
<View style={{width:400, height:100, flex:1, flexDirection:'row'}}>
<Image source={require('')}/>
<Text>Your Content Here</Text>
</View>
</Text>
Good luck. Please put a comment letting us know if it worked.
On android you cannot place a View inside Text, but you can place an Image, here is an example:
<Text>
<Image source="" />
<Text> Insert your text here </Text>
</Text>
Although this is an old post, I'll add this because I have recently had this problem and found a totally different approach that works for me. I don't have the code to hand (I can get it if anyone wants it), but the principle was this:
Requirement: to have a picture in the top left corner of the screen that takes up about half the screen width, with text starting to the right of it and then continuing beneath it for the whole width of the screen.
In XML, create a RelativeLayout containing an ImageView (IV) on the left and a TextView (TVA), set to wrap content, on the right. Then create another TextView (TVB) to sit below the Relative Layout. TVA is for the text beside the image and TVB for the text beneath it.
Put your image in IV. Then measure the height of IV in pixels (dpi). Call this height IVh
Put some of your text in TVA. As long as there is enough text to wrap over several lines, it doesn't really matter how much. Then measure the height of TVA in pixels. Call this height TVh
Compare IVh with TVh. If IVh=TVh then you have just the right amount of text to sit alongside your image. If TVh = IVh x 2 then you have twice as much text as you should have. And so on.
Adjust the number of words accordingly and put the right number into TVA, replacing what was there, then put the rest of the text in TVB.
You will need to play with margins and padding to allow an adequate margin around the image. Also, in steps 3 and 4 after you have put your image into ImageView or your text into TextView, you will need a delay before measuring the heights, to allow the display to be created - otherwise the measurement will be done too soon, before there is anything on the screen, and will return a height of zero. I found 200 milliseconds quite adequate and it's too fast for the user to notice a delay.
I've got an SVG that is being drawn inside of a div that has css of display:none. I need to center some of the rendered text elements, and to do this, I need the height and width. Unfortunately, when the containing html element is set to display:none, I always get 0 for height, and width. getBBox(), clientWidth, getComputedTextLength() methods all return zero. My question is: how can text width be calculated under these conditions?
e.g.
<div style='display:none;'>
<svg><g><text>some text</text></g></svg>
</div>
Have you tried setting the <div> to visibility: hidden;?
You may also want to make it position: absolute; so it doesn't affect the layout of other items on the page.
Using the Singularity Grid System:
I have a nested grid. Nothing fancy, just 2 column. Code is like this:
main-content { #include grid-span(8,1); }
sidebar { #include grid-span(4,9); }
It renders fine, but I keep getting undesired margins. The main content has a small margin-left and the sidebar has a small margin-right. I want these to have zero margins on the edge, similar to declaring main-content as "alpha" and sidebar as "omega."
Here is the CSS (at full desktop width):
main-content { width: 65%;float: left;margin-right: -100%;margin-left: 0.83333%;clear: none;}
sidebar-first {width: 31.66667%;float: right;margin-left: 0;margin-right: 0.83333%;clear:none;}
I didn't think this was default Singularity behavior, to add those small margins on the outer edges of my grid. Or is it? Can I get around it somehow? (besides just manually adding margin-left:0 and margin-right:0). Of course if there's margin on the outer edges, the total width of each DIV should increase as well (e.g. - for the main-content, instead of 65%, it'd be 65.83333)
I'm trying to make a series of photos into square photos. They may be rectangular horizontally (i.e. 600x400) or vertically (400x600), but I want to get them to be 175x175 either way. My thought was to max-height or max-width the smaller side, and not allow overflow beyond 175px on the larger side...however, I'm having problems with it.
Is this possible with css?
Below is my attempt, but it giving rectangles still:
<div style="min-height:175px; overflow:hidden; max-height:175px;">
<img style="min-width:175px; overflow:hidden; max-height:175px;" src="/photo.png">
</div>
You can set the width/height of the parent div then set the child img tag to width:100%; height: auto;
That will scale the image down to try to fit the parent with aspect ratio in mind.
You can also set the image as a background-image on the div
Then if you can use css3 you can mess with the background-size property.
It's attributes are: contain, cover, or a specificed height (50%, 50%) (175px, 175px)
You could also try to center the picture with background-position
<div style="background-image:url(some.png); background-size: cover; background-position: 50%">
Here's an up to date and simple answer.
For instance, if you want a squared image inside of a container.
Let's say you want the image to take 100% of the container height and have a dynamic width equal to the height:
.container {
height: 500px; /* any fixed value for the parent */
}
.img {
width: auto;
height: 100%;
aspect-ratio: 1; /* will make width equal to height (500px container) */
object-fit: cover; /* use the one you need */
}
You can switch width and height values (container & image) if you want to base the 100% on the container's width and have a computed height equal to the width.
You can use object-fit, which is widely supported in all major browsers. When set to cover, the browser will crop the image when you set the width and height properties, rather the stretching it.
<img src="whatever.jpg">
img {
width: 175px;
height: 175px;
object-fit: cover;
}
Okay I got this.
Don't know if it's too late or what, but I've come up with a 100% pure CSS way of creating square thumbnails. It's something that I've been trying to find a solution for for quite a while and have had no luck. With some experimentation, I've got it working. The main two attributes to use are OVERFLOW:HIDDEN and WIDTH/HEIGHT:AUTO.
Okay here's what to do:
Let's say you have a batch of images of varying shapes and sizes, some landscape, some portrait, but all, of course, rectangular. The first thing to do is categorize the image links (thumbnails) by either portrait or landscape, using a class selector. Okay, so let's say you want just to create two thumbnails, to make this simpler. you have:
img1.jpg (portrait) and
img2.jpg (landscape)
For HTML it would look like this:
<a class="portrait" href="yoursite/yourimages/img1.jpg"><img src="yoursite/yourimages/img1.jpg /></a>
<a class="landscape" href="yoursite/yourimages/img2.jpg"><img src="yoursite/yourimages/img2.jpg /></a>
So, at this point since there is no css yet, the above code would give you your full-sized image as a thumbnail which would link to the same full-sized image. Right, so here's the css for both portrait and landscape. There are two declarations for each (the link and the link's image):
.landscape {
float:left;
width:175px;
height:175px;
overflow:hidden;
}
.landscape img{
width:auto;
height: 175px;
}
.portrait {
float:left;
width:175px;
height:175px;
overflow:hidden;
}
.portrait img {
width:175px; <-- notice these
height: auto; <-- have switched
}
The most important things are the width and height and the overflow:hidden. Float left isn't necessary for this to work.
In the landscape thumbnail declaration (.landscape) the bounding box is set to 175 x 175 and the overflow is set to hidden. That means that any visual information larger than that containing 175px square will be hidden from view.
For the landscape image declaration (.landscape img), the height is fixed at 175px, which resizes the original height and the width is set to auto, which resizes the original width, but only to the point of relating to the bounding square, which in this case is 175px. So rather than smush the width down into the square, it simply fills the square and then any extra visual information in the width (i.e. the overflow) is hidden with the overflow:hidden.
It works the same way for portrait, only that the width and height is switched, where height is auto and width is 175px. Basically in each case, whatever dimension exceeds the other is set to auto, because naturally the larger dimension would be the one that would overflow outside of the set thumbnail dimensions (175px x 175x).
And if you want to add margins between thumbs, for instance a 5px white margin, you can use the border property, otherwise there will be no margin where the information is overflowing.
Hope this makes sense.
Determine width and height of image, then active portrait or landscape class of the image. If portrait do {height:175px; width:auto}. If landscape, reverse height and width.
I highly suggestion the NailThumb jquery plugin for anyone that is looking to do this. It allows you to create square thumbnails without distortion. http://www.garralab.com/nailthumb.php
This might help.
CSS:
.image{
-moz-border-radius: 30px; /* FF1+ */
-webkit-border-radius: 30px; /* Saf3-4 */
border-radius: 30px; /* Opera 10.5, IE 9, Saf5, Chrome */
}
HTML:
<div class="image"></div>
This worked for me. Just put the URL to the image inside the div.
