Currently I'm showing a single chart on my website in a responsive div, therefore it gets smaller as the screen width is decreased. My problem is: I'm saving an image of this chart but I need it to be always 700x400 even if my screen is 320x___.
lineChart.toBase64Image();
Is it possible?

I think there is a bug in Row and Column in flutter as you can see from the image attached below. I was creating a custom calendar and noticed that there is a small space between some items that varies with the screen resolution. So i tested it on the Web with the built in layout editor and i found the same bug.
If i change my page zoom the space comes and goes according to my zoom percentage as you can see the picture.
I need the solution to this problem as i am stuck on this last problem.
I wanted to know how the below functionalities can be achieved on tableau:
1. Resize the dashboard on the tableau server based on the screen size and
2. Maintain the % area occupied by each visual (worksheets on the dashboard) on the tableau server to be constant.
Ex, a visual should occupy 30% of the total width and 40% of the total height of the dashboard such that, regardless of the screen size, if this kind of height and width % are defined for every dashboard then the visuals will all be proportional to the screen size.
Situation:
I've built a dashboard with a lot of visuals (3 x 3 matrix of visuals) and each of different sizes. When I fix the size of the dashboard, it all looks good but when published on the server there's an obvious issue of scroll appearing on the web page depending on the screen size of the desktop it is being opened in.
I know tableau has an automatic resizing feature. But the issue is - I have almost 9 images on my dashboard and if I allow tableau to resize based on the screen, the height and width are out of control and some of the alignments are out of place as well.
Current settings:
I've made sure the worksheets on the dashboards are all within containers and I also know that i should not be fixing the height or width given we want the automatic resizing to work based on screen size.
I'm trying to display images in a fixed size box (the grey area in the image here). When the submit button is pressed new images will be fetched from the internet. But the images will be different sizes.
So to prevent the "submit" button moving up and down due to different size images (and potentially having it off the screen) I'd like the images to fit inside the box. (I suppose there are a few options there, for example having the image resize to fit in the box or having the image be clipped and still fitting in the box.) I've been messing with containers and columns etc for ages but nothing seems to work.
what is the best way to fit images of different sizes into a fixed size box ?
The Image widget can have a height be specified. You can read more about that here
Well, I am not expecting anyone else but jssor himself again to help me out with the best image slider plugin he made(jssor helped me earlier on stackoverflow). I wanted to make the jssor carousel responsive in terms of reducing the number of images shown inside the slide. As of now, the size of the images inside the carousel gets reduced as we move on to smaller resolution devices. However, at some point, this images look real tiny and are not desirable. This issue can be fixed, if we reduce the number of images shown inside the carousel for smaller screens. Like if we are showing 5 images on a larger screen, how do we show only 2 for considerable lower screens?
Waiting on you jssor!!! Keep on the good work you've done!
You know all elements in the slider will scale while window resizing.
As you set small size of your slider, and it scales to bigger size, the arrows looks bigger then.
2 ways to prevent it from scaling bigger.
first, Make the original size of slider bigger, it will prevent the slider from displaying with large scale ratio.
second, Suppress the arrows from scaling explicitly with data-noscale="1".
<span data-u="arrowleft" class="jssora13l" style="top:0px;left:30px;width:40px;height:50px;" data-noscale="1"></span>
<span data-u="arrowright" class="jssora13r" style="top:0px;right:30px;width:40px;height:50px;" data-noscale="1"></span>
Example: suppress arrows from scaling - jssor slider
I am using FB 1.3.
I have got images with a lot of text to show as title outside.
The problem is that the image itself is centered correctly but the title runs out of the viewport at the bottom. On smaller screens you cannot read the entire text whats pretty bad.
Any ideas?
